Hauv ib puag ncig ntawm lub Hoobkas, dej tsis kam yog qhov tseem ceeb ntawm tus cwj pwm -ib qho tseem ceeb "kev txawj ntse"- rau cov khoom sib txuas. Nws ua zoo li kev tiv thaiv "force field" enveloping lub connector, zoo barring lub intrusion ntawm noo noo thiab ua kom ruaj khov, txhim khu kev qha lag luam txawm nyob rau hauv ntub los yog ntub dej.
Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Ntau Yam: Cov khoom siv tiv thaiv dej feem ntau siv ntau - txheej txheej sealing - xws li silicone roj hmab gaskets thiab O- rings - los tsim kom muaj kev ruaj ntseg, tsis muaj dej thaiv ntawm qhov kev sib txuas. Tsis tas li ntawd, cov txheej txheem tsim khoom siab heev- suav nrog potting thiab ultrasonic vuam- feem ntau yog siv los txhim kho lawv cov dej ntxiv - muaj peev xwm tiv taus.
Water Resistance Ratings: Txhais los ntawm IP Codes: Cov qib ntawm cov connector cov dej tsis kam yog feem ntau tsim los ntawm tus IP code. Piv txwv li, qhov ntsuas IP67 qhia tau hais tias lub connector tuaj yeem tiv taus submersion hauv dej ntawm qhov tob ntawm ib 'meter' rau 30 feeb yam tsis muaj dej nkag; IP68 kev ntsuam xyuas qhia tau hais tias muaj peev xwm tiv taus lub sijhawm ntev submersion ntawm qhov tob dua.
