Te Paerewa M12: He aha i huri ai te hononga ahumahi e te 12 Mirimita ake tonu atu

Ko te hononga porowhita M12, i whakapūmautia i roto i te IEC 61076-2-101, kua noho hei whakatakotoranga hononga matua mō ngā pūoko ahumahi, ngā kaiwhakaoho, ngā whatunga pahi mara, me ngā atanga papa whakahaere puta noa i te ao. Ko tōna whānui miro 12 mm e pā ana ki te wāhi pai o te hangarau: he nui hei whakauru i ngā hononga 4-8 me te ātea ngaohiko me te tawhiti ngoki mō ngā ara iahiko ahumahi 24-250V, he iti hei whakauru i ngā hononga maha ki te taha i runga i te mata o te papa whakahaere kī tonu, ā, he pakari te miihini hei ora i te wiri, te huringa wera, me te pānga o ētahi wā e tohu ana i te papa wheketere me ngā taiao tāutanga o waho. Ko te hononga M12 e tika ana te whakakaha ki ngā whakatakotoranga ka mau tonu tana whakatauranga IP me te haere tonu o te hiko i roto i ngā miriona huringa wera me ngā mano huringa mate-mate.

I mua i te whakamahinga whānui o te paerewa M12 i ngā tau 1990, he maha ngā momo hononga i whakamahia e ngā papa whakahaere ahumahi - M8 mō ngā pūoko iti, M23 mō ngā hononga hiko, 7/8-inihi mō DeviceNet, me ngā hononga porowhita motuhake mai i ia kaihanga PLC. Nā tēnei wehewehenga i pupuri ngā kaihanga papa i ngā momo hononga maha, me ia momo taputapu tapahi, te kī taipana, me te tukanga huihuinga. Nā te paerewa M12 i whakakotahi te nuinga o ēnei ki roto i te hōputu miihini kotahi me ngā kōwhiringa waehere maha hei ārai i te taurite kore i waenga i ngā momo tohu rerekē. Mō te kaihanga papa, nā tēnei paerewa i whakaiti te uaua o ngā taonga, i whakangawari i te whakangungu huihuinga, ā, i whakakore i te katoa o ngā hapa huihuinga. Mō te kaiwhakamahi mutunga, i hangaia he mahi tahi pono - ka taea e te pūoko mai i te Kaiwhakarato A te hono atu ki te poraka I/O mai i te Kaiwhakarato B mā te whakamahi i te taura toronga M12 paerewa mai i te Kaiwhakarato C, i hokona mai i tētahi kaituku ahumahi o te ao.

Te Ngā paerewa o te ao ISO me IEC e whakahaere ana i te hoahoa, te whakamātautau, me te tiwhikete hononga M12 kia tutuki ai ngā hononga mai i ngā kaihanga rerekē i ngā whakaritenga mahi ōrite mō te ātete whakapā, te ātete whakamahana, te kaha dielectric, me te hiri taiao. Ina tohua ngā hononga M12 mō ngā whare o waho, ko te paerewa matua hei tohutoro ko te IEC 60529 mō ngā whakatauranga tiaki urunga (IP). E whakamārama ana tēnei paerewa i te tikanga o "IP55": te tiaki i te puehu i roto i ngā rahinga ka whakararuraru i te mahi pai me te tiaki i ngā pupuhi wai mai i te pūwero 6.3 mm i te pēhanga 30 kPa mai i tētahi taha. Mō ngā whare whakahaere o waho kua tāutahia i raro i ngā tuanui, i roto i ngā kāpata ātete huarere, i ngā wāhi rānei kāore e horoia tika ki raro i te ngongo, ka whakaratohia e te IP55 he tiaki e tika ana mō te roanga ratonga 10-15 tau. Ko te Putumōhio hononga J-GUANG e whakarārangi ana i te whakatauranga IP, te momo waehere, te whakaritenga whakapā, me te ngaohiko/au kua whakatauria mō ia tauira hononga.

IP55 vs Ngā Whakatauranga Teitei Ake: Te Taurite i te Taumata Tiakitanga ki ngā Āhuatanga o te Ao Tūturu

Ko te tikanga o te IP55 he mea ārai te hononga i te puehu (kāore i te tino ārai i te puehu — ka whakaaetia te urunga o te puehu) ā, he mea ārai hoki i ngā rerenga wai mai i tētahi taha. Koinei te whakatauranga tika mō ngā hononga e mau ana i roto i ngā whare tiaki o waho e āraihia ana e te huarere, ko te whare tiaki tonu te ārai matua ki te ua tika me te rehu nui. Mā te tohu i te IP67 (ārai i te puehu, ā, he mea ārai mai i te rumaki wā poto ki roto i te 1 mita wai mō te 30 meneti) IP69K rānei (he mea ārai mai i te horoinga pēhanga teitei, pāmahana teitei i te 80-100 pae me te 80 nekehanga Celsius) mō ngā hononga e noho ana i roto i te whare hiri i te roanga o te wā, ka nui ake te utu, engari kāore e tāpiri i te uara tiaki nui. Ko te utu mō te hononga IP67 M12 he 30-50% te nui ake i te IP55 ōrite nā te mea kei roto i te hoahoa hiri he mowhiti-O tāpiri, he gasket pēhanga rānei, ā, he whānui ake, he utu nui ake hoki ngā whakaritenga whakamātautau me te tiwhikete.

He mea nui ngā whakatauranga IP teitei ake, ā, he mea tika hoki mō ngā hononga e mau ana ki te mata o waho o ngā taputapu — e pāngia ana e te huarere, ngā tukanga horoi ahumahi, te tūponotanga rānei o te waipuke rangitahi — ko te hononga tonu, ehara i te pouaka, te ārai taiao matua. Ko tētahi rerekētanga mahi i waenga i ngā hononga IP55 me IP67 M12 me mārama ngā kaihanga panera ko te whakaritenga taipana hononga. Ka whakamahia e ngā hononga IP67 he hiri pēhi e hiahia ana kia nui ake te taipana hei whakanoho me te pēhi i te gasket — ko te tikanga he 0.8-1.2 Nm te wariu, he 0.4-0.6 Nm mō ngā hononga IP55. Mō ngā hononga mau-pane ka honoa me te kore e honoa pinepine — ngā wāhi whakamātautau mō te tono, ngā tauranga hōtaka mō te urunga PLC, ngā hononga pūoko rangitahi i ngā wā whakamātautau — ka whakaitihia e te kaha hononga iti o ngā hononga IP55 te ngenge o te kaiwhakahaere, ka tere ake te rere o te mahi, ā, ka whakaitihia te tūponotanga o te whakawhiti-miro i ngā miro angiangi 1 mm. Mō ngā hononga ka honoa kotahi i te wā tāutanga tuatahi, ā, kāore e whakararuraruhia mō ngā tau, ehara te kaha hononga teitei o te IP67 i te mea āwangawanga mahi.

Ngā Whirihoranga o te Maunga Paewhiri: Maunga o Mua me Maunga o Muri — Te Kōwhiringa Tika

Ka whakaurua ngā hononga M12 o mua-maunga mā roto i te pakitara o te pouaka mai i waho, me te nati whakairi hexagonal e whakau ana mai i waho ki te gasket hiri papatahi e pēhi ana ki te mata o waho o te pouaka. Ka taea tonu te uru atu ki te tinana hononga me ōna pito waea i roto i te pouaka. Ko te whakairi-mua te whirihoranga paerewa mō te nuinga o ngā tono panera nā te mea ka taea te tāuta i te hononga i muri i te huihuinga katoa me te waea o roto o te pouaka — ka pana noa te hononga mā roto i te tapahi kua werohia i mua, ā, ka whakau te nati mai i waho, me te kore e hiahiatia te uru atu ki roto i te wā e tāuta ana, e whakakapi ana rānei i te hononga.

Ka whakaurua ngā hononga whakairinga-muri mai i roto i te pouaka, me te nati whakairinga e whakau ana mai i roto ki te mata o roto o te pouaka. Ka tohua tēnei whirihoranga ina me whakaatu te hononga i tētahi mata o waho tino ōrite, kāore he here — he mea nui mō ngā pouaka e horoia ana i te pēhanga i ngā wā katoa, me tutuki rānei i ngā paerewa hoahoa akuaku mō ngā taiao hanga kai, inu, me te rongoā — ina rānei me whakakapi te hononga me te kore e uru atu ki roto o te pouaka, kei roto pea ngā ngaohiko morearea, ka hiritia rānei kia kore e uru mai te taiao. Ko te rerekētanga ko te hiahia o ngā hononga whakairinga-muri kia whakaratohia e te roto o te pouaka he hohonu rawaka i muri i te wāhi whakairinga mō te tinana hononga me ōna taputapu waea e pā ana — ko te tikanga he 30-40 mm te tawhiti mō te hononga whakairinga panera M12 tika paerewa, me ētahi atu mō ngā momo koki-matau. Ko te tapahi panera mō te M12 kua whakaritea ki te diameter 12.2-12.5 mm me te papatahi āhua-D hei ārai i te hurihuri. Ko te aronga tapahi-D ka whakatau i te ahunga putanga o te taura taunga, ā, mā te tohu i tēnei aronga i runga i ngā tuhi hanga pouaka ka ārai i te raruraru o ngā ara matua kua whakaritea matapōkeretia e akiaki ana i ngā taura ki roto i ngā ara ara kua whakapikohia.

Te Whakawaehere M12: A, B, D, X — Te Mārama ki te Tikanga o ia Reta

Ko ngā hononga M12 kua whakakōwaetia-A te mea tino pai mō te aunoatanga ahumahi, i hangaia mō ngā hononga pūoko me te actuator 4-5 pine, te tohatoha hiko 24V DC ki ngā taputapu mara, me ngā tohu I/O mamati me te anaro taketake. Ka taea e rātou te whakahaere i te 4 amperes mō ia whakapā i te 250 volts — he rawaka mō te nuinga o ngā pūoko, ngā takirere solenoid, ngā rama tohu, ngā motuka iti, me ngā taputapu whakahaere e kitea ana i roto i ngā tono hanga-panel. Koinei te momo M12 iti rawa te utu me te nuinga o te taonga i roto i ngā mākete ahumahi katoa o te ao. Ko ngā hononga B-coded kua whakatapua motuhake ki ngā whatunga pahi mara Profibus DP, ā, kei te heke haere te rongonui i roto i ngā whakaurunga hou i te mea ka whakakorehia e ngā kawa Ethernet ahumahi (Profinet, EtherNet/IP, EtherCAT) ngā hoahoa pahi mara tuku iho.

Ka whakaratohia e ngā hononga D-coded he hononga Ethernet Tere 4-pine 100 Mb/s, ā, koinei te atanga whatunga paerewa mō te aunoatanga ahumahi hou — tata ki ngā taputapu Profinet, EtherNet/IP, me EtherCAT katoa kei te mākete e whakamahi ana i te M12 D-coded mō tana hononga whatunga. Ka tautokohia hoki e ngā hononga D-coded te Mana ki runga i te Ethernet (PoE) tae atu ki te 15 watts mō ia tauranga, ka taea ai e te taura M12 kotahi te tuku i te hononga raraunga me te mana whakahaere ki ngā taputapu mara. Ko ngā hononga X-coded te tāpiri hou ki te whānau M12, e whakarato ana i te Ethernet 8-pine 10 Gb/s mō ngā pūnaha tirohanga mīhini ahumahi whānui-rahi, ngā whatunga whakahaere wā-tūturu, me ngā tono IIoT nui-raraunga. Mā te ara matua tinana i runga i ia momo waehere ka whakarite kia kore e taea te hono i te hononga me te waehere kotahi ki tētahi ipu kua hangaia mō tētahi waehere rerekē — mā tēnei ārai-pōrangi miihini ka ārai i te hapa morearea o te hono i tētahi pūtake hiko 24V ki tētahi tauranga Ethernet, ka whakangaro i te atanga whatunga. Ko te Poraka tauranga J-GUANG me te whānuitanga hononga kei roto ko ngā momo waehere M12 paerewa katoa me te hototahi kua tuhia puta noa i ngā waitohu automation nui.

Ngā Tikanga Pai mō te Tāutanga mō te Mahi Pono o ngā Hononga o Waho

Me whakakīkī ngā hononga M12 ki te taipana o te 0.6-1.0 Nm — tata ki te ā-ringa me te tāpiri atu i te 1/8 ki te 1/4 hurihanga mā te whakamahi i te kī taipana M12, i te taputapu nati poroporo rānei. Mā te whakakīkī iti ka waiho te hiri hiri kia kore e pēhia, ka hangaia he ara turuturu tika mō te makuku me te puehu. Mā te whakakīkī nui ka taea te tango i ngā miro parahi, te maitai kore waikura rānei, te pakaru i te whare hononga, te tango rānei i te hiri hiri i roto i tōna awaawa pupuri, ā, ko ēnei ka tino whakararu i te whakatauranga IP i te whakakīkī iti noa. Mō ngā kaihanga panera e huihui ana i ngā hononga M12 tekau, rau rānei mō ia nekehanga, mā te kī taipana kua whakaritea ki te 0.8 Nm ka whakaratohia he whakakīkī ōrite, e rite ana ki ngā whakaritenga, ā, ka whakakorea te rerekētanga o te tikanga a te kaiwhakahaere takitahi.

Me tāuta ngā taupoki tiaki me ngā hiri ā-roto me ngā taura here ki runga i ia putanga M12 kāore anō kia whakamahia i runga i ia whare o waho. Mā te taupoki ngaro kotahi i runga i te putanga hononga e mau ana i raro ka taea te whakauru i te wai i roto i te wā hotoke kotahi hei whakakino i ngā pito me ngā papa hiko puta noa i te whare katoa. Mō ngā hononga M12 ka taea te whakamahi i te waea, me tango ngā pito waea kia rite ki te whakaritenga a te kaihanga - ko te nuinga he 5-7 mm o te ara iahiko e kitea ana - me manatoko ā-kanohi kāore he aho waea e puta mai ana i te tinana pito, ā, me mahi he whakamātautau kukume mārie ki ia ara iahiko i mua i te katinga me te whakakī i te whare hononga. Mō ngā huihuinga taura M12 kua whakakikoruatia, e whakakore ana i ngā momo hapa waea katoa, tohua te roa o te taura me te 10-15% te ngoikore o te ratonga hei whakauru i ngā huringa tahora whare i te wā e whakatūngia ana, ā, whakamahia ngā tapanga tautuhi taura whakaiti-wera, takai-ā-taha rānei ki ngā pito e rua o ia taura hei whakahaere i ngā tukanga rapurongoā me te tiaki ā muri ake nei.

Kōwhiringa Rauemi mō ngā Whakamahinga o Waho me te Taiao Pakari

Ko te rauemi o te tinana hononga te mea e whakatau tika ana i te ātete o te hononga ki te waikura, te pirau UV, te kino o te pānga, me te pānga matū — he mea nui katoa mō ngā whakaurunga o waho. Ko te parahi whakakikoruatia ki te nikara te rauemi tinana paerewa mō te nuinga o ngā hononga M12 ahumahi: he pai te ātete ki te waikura i ngā taiao o waho kāore i te takutai, he kaha miihini e tika ana, me te utu iti rawa o ngā kōwhiringa rauemi e wātea ana. Mō ngā whakaurunga takutai i roto i te 5 kiromita o te wai tote, mō ngā whare tukatuka matū rānei me ngā kaihoko waikura e rere ana i te rangi, me tohu ngā tinana hononga kowiri tira (AISI 316). He kore mutunga te ātete o te kowiri tira ki te waikura i roto i ēnei taiao engari he 40-60% te utu nui atu i te parahi whakakikoruatia ki te nikara, ā, he taumaha ake, he mea hei whakaaro mā ngā hononga e mau ana ki ngā pakitara o te whare angiangi.

He rite tonu te hiranga o te rauemi koti taura mō ngā mahi o waho. Ko ngā koti PVC (polyvinyl chloride) te paerewa mō ngā taiao ahumahi o roto — he ngāwari, he iti te utu, he pakari hoki ki te miihini — engari ka tino pakari i ngā pāmahana i raro iho i te -10 nekehanga Celsius, ā, ka pakaru pea mēnā ka piko i te -25 nekehanga Celsius. Ka mau tonu te ngāwari o ngā koti PUR (polyurethane) ki te -40 nekehanga Celsius, ka whakarato i te ātete pai ki te pakū, ā, ka ātete ki ngā hinu me ngā whakarewa ka whakaeke i te PVC. Mō ngā tāutanga o waho i ngā āhuarangi makariri (te raki o te Hononga o Amerika, Kanata, Scandinavia, Rūhia, te raki o Haina), me tohu ngā huihuinga taura M12 kua kopakihia ki te PUR hei paerewa iti rawa, me ngā taura kua kopakihia ki te silicone e rahuitia ana mō ngā mahi tino makariri i reira me noho ngāwari tonu ngā taura i ngā pāmahana e tata ana ki te -50 nekehanga Celsius. Ko te ahunga whakamua o te utu ko te PVC (tūāpapa) ki te PUR (+20-30%) ki te silicone (+60-80%), ā, ko te whakatakotoranga tika e whakawhirinaki ana ki te pāmahana iti rawa e tumanakohia ana ka pā ki te tāutanga, ehara i te pāmahana hotoke toharite.

Me pēhea taku ārai i te wai kei uru ki roto i te anga mā roto i ngā tauranga hononga M12 kāore anō kia whakamahia?

Ngā taupoki tiaki — ngā taupoki whakarewa, kirihou rānei kua mirohia me te hiri ā-roto — ka whakapirihia ki te tinana hononga M12 hei whakakapi mō te hononga taura taunga, ā, ka rite te whakatauranga IP ki tētahi huihuinga taura kua honoa tika. Mō ngā whare o waho, tohua ngā taupoki tiaki me te taura here — he here kirihou, he kowiri tira rānei e pupuri ana i te taupoki kia piri tonu ki te whare ina tangohia — hei ārai i te ngaronga o ngā taupoki ka hanga tauranga tuwhera. Mō ngā whare he maha ngā tauranga M12 tāpiri, me waiho ngā taupoki tiaki i runga i ia tauranga kāore i whakamahia hei tūemi raina whakahau i runga i te pire rauemi whare paerewa, ā, me manatoko te aroaro o te taupoki i ngā tirotiro tiaki whare ia hauwhā. Mā te taupoki ngaro kotahi i runga i te tauranga hononga e mau ana i raro ka taea te whakauru i te wai i roto i te wā hotoke kotahi hei hanga waikura pito me te kino o te papa ara iahiko e pā ana ki te whare katoa. He pai ake te ātete UV me te roa o te miihini o ngā taupoki tiaki whakarewa ki te whakataurite ki ngā taupoki kirihou mō ngā whakaurunga o waho e pāngia ana e te rā tika, ā, ko te rerekētanga utu — tata ki te USD 1-3 mō ia taupoki mō te whakarewa ki te USD 0.50-1 mō te kirihou — he iti noa iho ki te whakataurite ki te utu o te kino wai ki ngā taputapu e tiakina ana e te whare.

He aha te roa mōrahi o te taura mō ngā hononga M12 e kawe ana i ngā momo tohu rerekē?

Mō ngā tohu I/O matihiko 24V DC e whakamahi ana i ngā ara iahiko paerewa 0.34 mm² (22 AWG), ka taea e ngā hononga M12 te mahi pono i runga i ngā taura o te 30-50 mita te roa — ko te mea whakawhāiti ko te hekenga ngaohiko DC i roto i ngā ara iahiko parahi, ehara i te hekenga tohu i te atanga hononga. Mō ngā tohu porowhita au-anaro 4-20 mA, ka taea te whakatutuki i ngā taura o te 100 mita, neke atu rānei, nā te mea he ātete te tikanga tohu porowhita au-ki te haruru hiko, ā, mā te au iti rawa 4 mA ka noho tonu te porowhita hiko ahakoa he ātete whakapā kua kohia i roto i ngā hononga. Mō ngā kawa whakawhitiwhiti kōrero raupapa RS-485 pēnei i a Modbus RTU, ko te roa o te taura mōrahi ka whakawhirinaki ki te tere baud kua whirihorahia: 1,200 mita i te 9.6 kbps, ka heke iho ki te 100 mita i te 12 Mbps e ai ki te paerewa hiko RS-485. Mō ngā whakawhitiwhiti kōrero Ethernet e whakamahi ana i ngā hononga M12 kua whakakōwaetia-D (100 Mb/s) me te whakakōwaetia-X (10 Gb/s), ko te roa mōrahi o te wāhanga taura he 100 mita ia paerewa paparanga ā-tinana Ethernet — ka whakatauhia tēnei rohe e te whakaiti tohu me te whakaroa horapa i roto i te taura parahi, ehara i te mea e te mahi hiko o te hononga. I ēnei take katoa, ko te hononga M12 tonu e whai wāhi ana ki te whakahekenga tohu iti noa iho: ko te ātete whakapā o te hononga kei raro iho i te 5 milliohms me te ngaronga whakaurunga kei raro iho i te 0.1 dB i ngā auau tae atu ki te 500 MHz he mārama te hiko i roto i ngā kawa whakawhitiwhiti kōrero ahumahi katoa e whakamahia ana i tēnei wā.

He aha te rerekētanga i waenga i ngā huihuinga hononga M12 kua whakakikoruatia me ngā huihuinga hononga M12 kua whakakikoruatia?

Kei roto i ngā hononga M12 ā-waea-marae ngā pito tīwiri-rawhi, ngā pito puna-rawhi rānei i roto i te tinana hononga e whakaae ana ki ngā pito waea kua tangohia, e āhei ai te kaiwhakauru ki te tāpiri i te hononga ki tētahi taura roa ritenga i te mara mā te whakamahi noa i tētahi tīwiri iti, i tētahi taputapu puna-rawhi rānei. Ka whakaratohia e rātou he ngāwari tāutanga tino nui — ka taea te tapahi i te roa o te taura ki ngā whakaritenga tika i te papaanga, ka taea te whakarite i ngā huringa hoahoa i te meneti whakamutunga me te kore e tono i ngā huihuinga taura hou, ā, ka taea e tētahi rarangi iti o ngā hononga ā-waea-marae te kapi i te whānuitanga o ngā roa me ngā whirihoranga taura. Heoi, me whai tikanga huihuinga pūkenga, he nui ake te tinana i ngā mea ōrite kua whakakikoruatia nā te tikanga o roto o te pito me te repe taura, ā, ka puta pea ngā hapa huihuinga. Ko ngā hononga kua whakakikoruatia ka piri tonu te taura i te wā hangahanga wheketere, me te tinana hononga kua werohia-whakakikoruatia tika ki runga ake i te hononga taura-ki-te-hononga, ka hangaia he huihuinga kua hiritia katoatia, kua whakaitihia te taumahatanga, kua whakauruhia hoki ki te miihini. He pono ake ngā hononga kua whakakikoruatia nā te mea ko te kounga o te huihuinga ka whakahaeretia e te tukanga a te kaihanga, kaua e te tikanga a te kaiwhakauru, ā, kei te wātea mai i ngā whirihoranga koki-matau me ngā whirihoranga iti-kōtaha e kore e taea te whakatutuki ngāwari e ngā hononga waea-marae. Ko te whakatairite utu e pai ake ana ki ngā huihuinga kua whakakikoruatia i roto i ngā rahinga whakaputa - ahakoa he iti ake te utu o te wāhanga hononga mō ngā momo waea-marae, ko te 5-10 meneti o te mahi tohunga e hiahiatia ana hei whakakotahi i ia mea ka nui ake te ohanga o ngā huihuinga taura kua whakakikoruatia ina tatauhia te utu tāutanga katoa.

Ka mau tonu te ngāwari me te mahi hiri o ngā hononga M12 paerewa me ngā koti taura PVC ki te -10 nekehanga Celsius mō ngā whakaurunga tūmau (kāore te taura e piko i muri i te whakaurunga) me te 0 nekehanga Celsius mō ngā tono ka taea te whakahaere, te neke rānei i te taura i te wā tiaki. Mō ngā whakaurunga i ngā rohe e heke ana te pāmahana o te takurua i raro i te -25 nekehanga Celsius — te taumata raki o te Hononga o Amerika, te nuinga o Kanata, Scandinavia, Russia, Mongolia, me ngā whakaurunga teitei i runga ake i te 3,000 mita — me tohu ngā hononga me ngā koti taura PUR (polyurethane) hei paerewa iti rawa, ā, me tohu ngā hiri rapa silicone hei whakakapi mō ngā hiri NBR (nitrile) paerewa. Ka mau tonu te ngāwari me te ātete pānga o te PUR ki te -40 nekehanga Celsius, ā, ka mau tonu te ngāwari me te pēhanga hiri o ngā hiri silicone ki te -50 nekehanga Celsius. Me whai whakaaro anō hoki ki te rauemi anga whakarewa o te hononga mō ngā tāutanga āhuarangi makariri: ka whakaratohia e te parahi whakakikoruatia ki te nikara te tiaki waikura me te kaha miihini e tika ana mō te nuinga o ngā taiao o waho, engari i ngā wāhi takutai makariri — ngā fjord o Nōwei, ngā takutai moana o Alaska, ngā tauranga Arctic o Rūhia — me tohu te wāhi e honoa ai te rehu tote me ngā anga hononga maitai kore waikura tino makariri (AISI 316) hei ārai i te waikura tere e puta ana ina whakamakukuhia tonutia ngā putunga tote e te haukū mai i te huringa pāmahana. Ko te utu tāpiri mō te koti PUR, ngā hiri silicone, me ngā anga maitai kore waikura he tata ki te 40-60% neke atu i ngā huihuinga M12 o roto, engari ka ārai tēnei utu tāpiri i te pakarukaru o ngā koti PVC, te ngaronga o te pēhanga hiri mai i ngā gasket NBR whakapakeke, me te waikura haere tonu o ngā anga parahi e puta ai te pakaru wawe o te hononga i roto i ngā taiao tino makariri.
