Np Sensor Tester Wiring Diagram

This is a three wiring sensor one wire is used for sensor power the other two go directly into the computer for sensing purposes. Looking for what wire is what on the speed sensor plug. In hazardous or explosive atmospheres special care must be exercised to determine the classification of the hazard and to employ components with an approved.

Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor.

Np sensor tester wiring diagram. When connecting to the plc the plc input acts as the load. The following is a wiring diagram of an open collector npn sensor. Any help would be much appreciated. The v brown will be attached to the common input and the switching wire black will be attached to the input number.

Normal conditions s terminal voltage. It was cut off so i don t know what one is 5 sense and ground and i need to splice it into my swap harness so no wire colors will match up. Ig on engine off turn on the main switch. 7 with the circuit tester.

Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. My plug has purple orange brown yellow white orange. 7 6 1v connect the lead of the tester.

Once system power is confirmed with the key on the next step is to test the connection between the sensor and the computer which will find broken wires. Lead of the tester diagram viewed from fitting side of 2 water proof connector turn the ignition switch on. You will notice that the load appears between the v brown and switching wire black. Check voltage of the s terminal shown in fig.

Referring to the npn wiring diagram above note that the sensor supply voltage and the high side of the load are connected to the same point and are therefore at the same voltage. Oh it came off a 2000 2 5l tj if that helps.
