QUESTION
How can I do this without burning up the prox switch? I have used prox switches in the past with plcs and have never had any problems. I am trying to control a relay and the prox switches keep burning up. Do I need a different relay? It is a 120 VAC circuit.

Rapidly switching a relay with a proximity switch will cook something.
Can you use an opto-relay for what you’re doing? They automatically provide zero crossing, (or not), if your application would revolt. You can get them in AC or DC. They require only about 5mA to switch which unburdens the prox switch greatly.
