Photoelectric Sensor Switch, 90-250V AC 3A E3JK-R4M1 Specular Reflection Photoelectric Switch 5 Wire Retro-Reflective Photoelectric Beam Sensor with Screws

Nothing

The media could not be loaded. Works, but instructions poor.My unit only accepted 240V AC power, did not work with 12V or 24V from the Neco unit.So connect brown and blue to Live and Neutral of Neco respectively, instead of the 24V and earth pins on Neco.The other wires are the Relay Common, NC, NO connections.White wire is common, and goes to common pin 19 of Neco. Pin 19 is then joined to pin 21 ( common )as per Neco instructions.Grey wire is "normally open" and goes to pin 17 which is safety input of Neco.Black wire is "normally closed", and is not used for Neco.Range good with the reflector (2.5M in my case) and responsive.I attached to garage door with self adhesive velcro, for both sensor and reflector. The reflector was mounted to opposite wall. Not too finicky in terms of alignment.Good luck

good product

Good value, was quoted 3 times more by door manufacturers

Set this photoelectric switch up to control a garage door initial impressions were good as the beam worked and I tested at 3 meter which is good - The bad bit is that when i tested the NO and NC relay contacts i found a voltage accross them - So be Aware !!!!

Just what I expected, not used yet, quality looks fine for the job it was bought for.

When I wired the sensor in it does not have a beam to the reflector. There is power to the unit but no infrared beam.
