## Questions & Answers

**Q: dumb question but does this only detect proximity of metal or magnetic device or would it detect  a human finger being used as no-touch switch?**
A: Metal only.  It does detect any metal however.

**Q: Is it waterproof?**
A: It is sealed and stainless so it is very water resistant. It's not made to be submersed in water, though it could last for a time underwater. The sensor can take a light stream of water, but would likely fail under high pressure washdown over time.

**Q: How sensitive is this switch to aluminum?  4mm?  2mm?  Thanks**
A: Distance or thickness of material?  I was able to trip it with a small aluminum tube but it had to make physical contact with the center of the switch.

**Q: it is assumed sensor has voltage applied; is sensor closed then opens when tripped?**
A: Depends on if it a normally open or normally closed sensor.
