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: 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?

Metal only. It does detect any metal however.

Q: How sensitive is this switch to aluminum? 4mm? 2mm? Thanks

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?

Depends on if it a normally open or normally closed sensor.
