Capacitive sensor wiring

[netflixandphil]

I'm trying to wire in a 4 core capacitive sensor into a safety circuit. I have brown, blue, white and black coloured cores and it's a NO sensor. What's the best way to wire this into a safety loop

I am an apprentice and the sensor didn't come with any drawings, the info on the sensor just say 250v max and that it's normally open

very few capacitive sensors are suitable for direct insertion into a safety circuit.
the only ones that i have ever come across have there own controller that deals with the error checking etc and duel redundancy required for anything other than the most basic of system.

at very least i would expect you to need a safety relay .
do you have a machine wiring diagram?
