How to wire / program Allen Bradley 802b limit switch

Any one have experience with a Allen Bradley 802b limit switch? We are not sure how to wire it.


Based on the image below, you should be able to wire it either as a Normally Open or Normally Closed switch based on which wires you choose.

Blue/Black - Normally Open
Brown/Black - Normally Close

The green/yellow and brown or blue wire not being used can be ignored.

You’ll need to tie them into a PWM connector as shown here using the S and Ground(Common) pins on the DIO:

Which wire ties to which pin shouldn’t matter as its just a switch, I personally like black being to the “ground”.

Here is the site I found documentation, the 802B starts on page 65.

Thank you! this is very helpful.
