Difference between PNP and NPN sensors
• PNP sensors are sometimes called “sourcing sensors” because they source positive power to the output.• NPN sensors are sometime called “sinking sensors” because they sink ground to the output. • The term “load” identifies the device the sensor powers. The load could be a lamp, pneumatic valve, relay or PLC input.
