IP yog cov ntawv luv ntawm ingress tiv thaiv kev ntsuas (lossis thoob ntiaj teb kev tiv thaiv code), uas txhais tau hais tias muaj peev xwm tiv thaiv kev cuam tshuam ntawm cov kua thiab cov khoom siv. IP yog ua raws li 2 tus lej. Thawj yog qib kev tiv thaiv solid-state, xws li los ntawm 0 mus rau 6, uas feem ntau sawv cev rau kev tiv thaiv los ntawm cov khoom loj txawv teb chaws rau plua plav; Qhov thib ob yog qib kev tiv thaiv kua, xws li ntawm 0 mus rau 8, uas feem ntau sawv cev rau kev tiv thaiv los ntawm cov dej ntws ntsug mus rau hauv qab dej siab. Tus lej loj dua, lub peev xwm muaj zog dua. IP67 yog txhais raws li kev tiv thaiv kev nqus plua plav (tag nrho kev tiv thaiv tiv thaiv kev sib cuag thiab plua plav nkag); Kev tiv thaiv: luv immersion (anti immersion). Tam sim no, qib siab tshaj plaws hauv kev lag luam cable yog IP68. Tsis tas li ntawd, cov khoom sib txuas kuj tseem xav txog lwm qhov chaw hnyav xws li kub thiab av qeeg.
IP67 qib waterproof txhais tau tias covindustrial vaj huam sib luag PCNws yog resistant rau immersion dej mus txog qhov tob ntawm 1 meter rau 30 feeb. Qhov no ua kom paub tseeb tias cov cuab yeej muaj kev tiv thaiv kev phom sij ntawm cov dej thiab tuaj yeem siv rau hauv qhov hnyav sab nraum zoov lossis chaw ua lag luam uas raug cov dej noo, plua plav, thiab av. Kev ntsuam xyuas IP67 muab qib siab tshaj plaws ntawm kev tiv thaiv dej nkag, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau qib siab ntawm kev ua haujlwm ntev thiab kev ntseeg siab.
