NPN sensors yog ib hom sensor dav siv hauv kev lag luam automation thiab tswj tshuab. Kev nkag siab txog cov xwm txheej ntawm kev siv thiab ib puag ncig cov cai ntawm NPN sensors yog qhov tseem ceeb los xyuas kom meej qhov ua haujlwm zoo thiab kev ntseeg siab ntawm cov sensors. Kab lus no yuav qhia txog kev siv NPN sensors thiab cov ntsiab lus cuam tshuam los pab koj xaiv thiab siv NPN sensors kom raug.
Cov hauv qab no yog cov ntsiab lus tseem ceeb ntawm kev ua haujlwm thiab kev siv ib puag ncig rau NPN sensors:
Ua haujlwm voltage:
Kev khiav hauj lwm voltage ntau: 3-30 volts (V)
Pom zoo ua haujlwm voltage: feem ntau 12 volts (V)
Ambient Kub:
Ua haujlwm kub ntau:-25 degree rau +70 degree
Pom zoo ua haujlwm kub: feem ntau yog 0 degree rau +60 degree
Humidity:
Kev ua haujlwm humidity range:0% mus rau 95% txheeb ze humidity (non-condensing)
Pom zoo ua hauj lwm humidity: feem ntau 10% mus rau 90% txheeb ze humidity
Kev vibration thiab shock:
Vibration kam rau ua: raws li cov qauv thoob ntiaj teb (piv txwv li, IEC 60068-2)
Kev poob siab tsis kam: raws li cov qauv thoob ntiaj teb cuam tshuam (xws li IEC 60068-2)
Environmental ntsuam xyuas:
Kev tiv thaiv kev ntsuas: feem ntau IP67 lossis zoo dua nrog plua plav thiab dej tsis kam
Installation xav tau:
Qhov chaw installation:tsis txhob raug rau huab cua ib puag ncig xws li kub, high humidity, muaj zog electromagnetic cuam tshuam, thiab lwm yam.
Kev sib txuas kab:raug xaim kom ruaj khov thiab cov teeb liab kis tau tus mob
