Inductive prox wiring practice

Inductive prox wiring practice

Inductive prox wiring practice

(OP)
Need to assemble a simple box with relays to provide another vendor with dry contact signals for position of 10 metal gates spaced 10 ft apart in a 100 ft string. First thought, 120V push-to-test relays, coils wired in series w/2 wire AC proxes - all conductors in a single EMT conduit, nylon strain reliefs at T conduit bodies for (wire nut) prox connections. So, one (fused) hot conductor shared by all proxes, 10 output conductors back to the relay box . . .

Do those conductors need to be shielded from each other, or can we just use THHN? Any issue "pushing" coil current 100 ft through a prox?

We could go with a power supply & DC proxes & relays, still have those same wiring questions.

Any feedback would be appreciated. I prefer to think these things through, look at lots of specs & search lots of forums but no time, must spec & Red Label parts today . . .

Bentov, ahve you considered ASIBus, because it sounds like you have a conveyor installation, and this would be a perfect application for this, with very simple wiring, and alittle bit of configuration.
