Proximity limit switch problems

[EddyCurrent]

Try your 2 wire proximity with Blue to GND and Brown to the input.
One problem is the voltage, the inputs are probably 5v but could be 12v, your switch is 6v minimum.
I think 3 wire is better but you did not connect the 3 wire switch correctly, you need brown to +ve(12v), blue to -ve(GND), black to input.

Great thanks Eddy, will try this tonight and let you know if it worked. Much appreciated.

Eddy's correct but you'll need to make sure the input and switch share the same Dc Ground (-ve). If you Control has a 12V source then your probably sorted.

Another thing you may be having trouble with is that I'm 99% sure the Old switches will have been wired in series but with these NO (normally open) swithces you'll need to wire them in parallel. . . . . . . Chances are that's what Mechant dicey where meaning.?

Easy to way wire these 3 wire switches is to run each switch back to a box on machine and connect all switches together in there then just run a single 3 wire Cy cable back to the control box.
