PNP lossis NPN tso zis?

Thaum koj xaiv peb lub siab hloov pauv nyiamUPS 1thiabUPS 2cov qauv, uas tso zis koj xav tau: NPN lossis PNP?

NPN thiab PNP feem ntau sib txawv nyob rau hauv cov kev taw qhia ntawm tam sim no thiab qhov zoo thiab tsis zoo voltage. Txhawm rau muab nws "kev tshaj lij", nws yog qhov teeb meem ntawm "polarity". Cov ntawv tso zis tawm yog diametrically tawm tsam, uas yog, qib siab thiab qib qis. PNP cov zis yog qib qis 0, NPN cov zis yog qib 1.

PNP thiab NPN sensors feem ntau muaj peb txoj kab hlau lead, uas yog lub hwj chim kab VCC, 0V kab, thiab cov teeb liab tso tawm kab.

Muaj kev txaus siab, xav tiv taujStella Meng.
