TC102 Photocell Infrared Beam Sensor Safety Photoelectric Motion Detector for Automatic Swing Sliding Gate Openers Garage Door Openers Security Alarm Systems Access Control Outdoor Use

Excellent little sensors, easy to install and worked first time. Note they do not have side entry for the cable, only from the rear. The instructions say to mount on a wooden base plate (not provided) and drill that out for side entry which was easy enough to make. The included rubber seals look like they will do a decent job of weatherproofing. I also like that the covers have screws rather than being snap-on. The manufacturer would do well to modify these to allow both s ide and rear cable entry in future.

Super product, works perfectly with our electric gate opener from the same company. Very pleased with it.

Another excellent product in the TOPENS range for electrically operated gates.

These were brought as spares just incase I had a faulty set, still in the box. These sensors are easy to fit and set up.

Both units require 12 to 24-volt power. the receiver incorporates a relay with NO/COM/NC connections so it can be used to 'break' or 'make' upon beam interruption.I used this in my driveway to provide notification when someone enters my drive. I adapted a wireless door sensor that links to my Amazon Alexa, so this trigger can be used to trigger routines to achieve various tasks. In my case turn on the lighting if dark, trigger a camera and provide an audible warning and notification to my phone. Obviously, it can be used to directly operate a powered gate or garage door for example. It has a multitude of uses with a little thought and ingenuity.

I was looking for a sensor which I could use in a camera trap. I couldn't make such a sophisticated circuit myself so I had to borrow from available tech. It works straight out of the box but needs a latching system to ensure that when triggered it stays that way, so a picture can be taken of even a fleeting interruption of the light beam. Latching system just used a thyristor which stays triggered until reset.

I purchased an RK990T sliding door opener kit two years ago and found it very straight forward to fit with the instructions provided. The TC102 photo cells failed due to my actions and the diagnostic support was speedy, competent and friendly. The new photocells arrived next day and are now working perfectly. Thank you.
