Hello,
I have purchased two of these "Inductive Proximity Sensor 18mm - LJ18A3-8-Z/AX" sensors and I have a different problem with each of them.
I supply them with 12V. The first one has a voltage difference between + and signal of 12V, the led reacts to metal surfaces approaching the sensor, but the difference doesn't drop to 0 (it stays 12V). The second one has voltage difference between + and signal but also between - and signal, the sum of which are 12V. There is also no continuity between signal and - for the second instance. Does anyone know whether I could fix any of them?
