## Questions & Answers

**Q: Is it water proof?**
A: The spec published on the Amazon description page says the protection is IP65.
Google that term to get your answer

**Q: Will this sense transparent bottles going by it on a conveyor belt**
A: If it is very transparent, there is no way to detect it.
 If it is translucent, it can be detected.

**Q: Can I use a power supply instead of batteries as long as I keep the voltage and amp.  ?**
A: The voltage must meet the requirements of 12-240 VDC 24-240 VAC.

**Q: Does it work with co-z brand gate opener? are there install instructions?**
A: I'm not sure how you will be using it. The relay Output Current is 2 amps for your control out connection. So as long as you only draw that or less you are OK. I use it to tum on a low voltage light.
