TRF3 Retro Reflective Beam Sensor for Gate Opener

Sale price$79.00

● TOPENS TRF3 Reflection Photocell Sensor is an outdoor photoelectric sensor with rapid response. It creates a safety barrier that detects any movement in its path. Once triggered, it perfectly makes the gate stop or reverse automatically in case of obstruction. It is strongly recommended to use the TRF3 reflective sensor with automatic gate opener system to ensure multiple protection & security.

● Works with all the TOPENS gate openers, and compatible with most third party swing / sliding gate opener or garage door opener whose control board accepts “Normal Open or Normal Close Dry Contact” signal. It can be powered by the control board of the gate opener or by the external 12-30VDC or 10-25VAC power source. This safety beam sensor is commonly used for the household, courtyard, farm, ranch, warehouse and other commercial / industrial sites.

● Simple wire connection makes the installation labor-saving. Just connect the retro-reflective photocell to the gate opener system. It is suggested to mount the photocell at least 8” (20cm) above the ground. Power on to determine the reflector position. Ensure that there is no obstruction between the photocell and the reflector during alignment. Fix the reflector position when the photocell status LED is green.

Great addition to my Topens Gate

For safety, for helping me “see” exactly where my gate is, these are a great addition!

Great for saftey

It works great and is important for saftey to prevent someone from getting injured or a vehicle from getting damaged. Aligning the light beam during install is a little bit tedious. I found doing it at night is a little bit easier.

A must have

All our gates utilize these sensors. Dont worry if your gate will hurt someone or damage someones vehicle, set things up for worry free operation.

TRF3 Reflective Photo Cell

Installed and works well, but we ended up removing due to the kids pushing the button to close then running through to catch the bus.
