PNP Inductive Proximity Sensor LMF15 Series Sensors Introduction:
- To know this LMF15 PNP inductive proximity sensor, firstly we need to know what it is. A PNP sensor is a 3 wires sensor, its output is high voltage when a metallic object is within detection range. So, to form a complete circuit, the output wire(black color) with a load should connect to ground(0V).
- Lorentzzi LMF15 series sensors’ appearance is the same as Balluff BES02MW sensor.
- Compared with Balluff sensor, our sensor outputs can be PNP, NPN or two wires AC output. The models are LMF15-3002P_, LMF15-3002N_.
- How to wire this PNP inductive proximity sensor better, you can wire it according to the below diagram:
-
- As we all know that an inductive sensor can only detect metal products, but if you want to detect materials without limitation, a photoelectric sensor is the best choice.
- One thing to be noted is that as the output current is very small, generally only few milliampere, so it can’t run a heavy load directly, we can rely on an intermediate relay, AC contactor, or SSR to realize.
