Mag ic proximity switch wiring diagram. When a magnet is reached in proximity of s1 it closes to give a negative trigger at pin 2 of ic1 the output of ic1 goes high for a time determines by r2 and c2 this clocks the ic2 wired as. Wiring diagrams show the hook up offour sensors with npn and pnp outputs. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia. 1 5 khz ni brass pvc 26 awg 2.
A monostable multivibrator based on ne555 ic1 and a toggle flip flop based on cd4013 ic2 does the rest of the circuit. Two three or four wire proximity sensors contain a transistor oscillator and a. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. As a consequence its output at pin 3 goes high for a short duration and supplies clock to the clock input pin 3 of ic2 cd4013 dual d type.
Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.

H ere is the circuit diagram of a magnetic proximity switch that finds a lot of applications in many fields the circuit is based on a magnetic reed switch s1 as the proximity sensor.
Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. The schematic diagram symbol for a proximity switch with mechanical contacts is the same as for a mechanical limit switch except the switch symbol is enclosed by a diamond shape indicating a powered active device. 12 nj2 12gm40 e2 2 flush pnp n o. 3 wire and 4 wire dc.
Many proximity switches though do not provide dry contact outputs.
