An FYI to anyone who decides to use Sharp IR Proximity Sensors such as
this.
We checked the isolation of our Electrical System yesterday (IAW R37) and found we had a short between our frame our electrical system. After some frantic searching, we found the issue was due to the Sharp Proximity Sensors we are using. With much hair pulling, we discovered the housing is made of a "conductive resin". We verified this using a multimeter with significant pressue to the case (similar to what it would see when screwed down). Our solution was to use nylon washers/standoffs and nylon screws to secure the sensors instead of standard metal screws.
I hope I can save some people some panic if anyone is using these.
