Answer Posted / anand raj
Proximity sensors are of different types, and the circuitry
can use NPN or PNP switching. I personelly have worked with
NAMUR inductive type proximity sensors where we supply
positive 7.2 to 8 volt to the sensor. When a metallic target
is in its visinity the voltage drops to 4 volts switching
the relay. So dont know if this question is completely correct.
