I decided to upgrade my cheap proximity switches and makeshift wiring for some Pepperl & Fuchs ones.

Seemed like a good idea, until now!

The ones I’ve bought are PNP https://www.pepperl-fuchs.com/global...ils&prodid=514.

I’ve hooked them all up and they light up when metal is placed in front of them.

Problem is, in Mach 3 th fact that the switch is tripped doesn’t register.

When I add my old Chinese cheap switch, it works fine.

Seems that the issue is that my old ones were NPN and the new ones are PNP.

can anyone tell me whether this is easily fixable by some tweaks to the wiring or am I better off just getting NPN sensors?

If any more information is needed to answer the question I’ll fill the gaps.

Thanks in advance
