Hello. I wont be able to get the full type number of the sensor for about 3 weeks as it is on our machine at another spot in the country. As for the relay I am using it is this one attached. I think I am starting to see what you are saying. Thanks for the help.Or just a link to the type of relay. The point here is that the different models of sensor have different output circuits; one requires the relay coil return to positive, one requires it to go to negative, one probably doesn't matter. The sensor's 100mA output current rating is sufficient to drive some relays but not all; yours may well be presenting it with a borderline overload and triggering its output protection if the coil resistance is too low.
Re wiring, no, the cable size is more or less immaterial at these low currents, any normal cable physically strong enough to use will be ample for the sensor circuit unless it's tens of metres long.
