Change the PNP (NPN) proximity sensor to NPN (PNP)

The polarity of the proximity sensor has two types, PNP and NPN. We show you how to change the PNP (NPN) type proximity sensor to the NPN (PNP) type.

what are the values for R1 ? PLS... nice info

[@diwanjakhar6271]

Sir vo kon sa sensor hota hai jo sense na karne pur +tive 24 output deta hai.

how do you calculate the values for R1 and R2? an dwhat type of npn transistor can I take?

[@axelateon1384]

kon

R1 is limiting your transistor max current. R1=Uvcc/Imax
R2 limiting base voltage and depend on max base-collector voltage and input impedance base-emitter resistance. R2 and Rbe creates divider. so Ube/Uvcc=R2/Rbe
Imax, Uce_max, Rbe are in datasheet
