Mag Ic Proximity Switch Wiring Diagram

When a magnet is brought placed in the vicinity of the sensor element for a moment the contacts of the reed switch close to trigger timer ic1 wired in monostable mode. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Click on this link.

Mag ic proximity switch wiring diagram. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia. 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. 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.

Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. 3 khz ss pur 22 awg 1 nbb2 12gm50 e0 2 flush npn n o. Two three or four wire proximity sensors contain a transistor oscillator and a. Many proximity switches though do not provide dry contact outputs.

12 nj2 12gm40 e2 2 flush pnp n o. 1 5 khz ni brass pvc 26 awg 2. Wiring diagrams show the hook up offour sensors with npn and pnp outputs. 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.

A monostable multivibrator based on ne555 ic1 and a toggle flip flop based on cd4013 ic2 does the rest of the circuit. 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.
