## Questions & Answers

**Q: Could you please provide instructions about wiring and usage?**
A: There is an attached wiring diagram on the switch connecting wire.This product is widely used in outdoors gates, garage doors, Weatherproof (IP66) construction for indoor/outdoor usage etc.
Supply Voltage:6-36V DC;Type : NPN（normally open ）;Wire Type : DC 3 Wire,Proximity-sensing / Opposite Type
Sensory Distance : 0-20m；Sending Light : Infrared Rays;Current : 300mA;Thread diameter: 12mm/0.47"

**Q: will these work as  single unit and trigger if object is sensed by the beam?**
A: Yes. It will send a signal every time the beam is broken thru a 3rd wire. You do have to have a counter or something attached to accept the signal

**Q: what is the switching speed of the npn receiver?**
A: The actual switching time is about 2-3 microseconds on the one I've bought, but the minimum "break" time it responds to reliably seems to be at about 10 milliseconds with a 10K load resistor. you could probably increase the sensitivity with a  larger load resistor but I haven't tried.

**Q: This product is not infrared!.  it is red laser dot.  do you have one that is really infrared (>800nm)?**
A: I don't have one, sorry. Issue an open ended purchase order and I will develop one just for you. Thanks.
