Pnp Schaltung Sensor. For this example we ll wire a 3 wire proximity sensor to a discrete dc input card and walk through both pnp and npn wiring types. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor.
No physical contact means that the switch has no parts that will wear out. In this video we go over the basics of what an inductive sensor is and how they work. The selection of a pnp sensor relative to an npn sensor is determined by the nature of the circuit the device is to be used in.
A proximity sensor switch is able to detect object presence without physical contact like a limit switch.
The yocto pwm rx can also read an npn or pnp output. First select a sensor that matches your plc input card discrete dc input and has the same circuit wiring type pnp or npn. The life span of the senso. The pnp device has 2 power control leads one connected to the positive one the other negative.
