Review: Easier to install and effective - This product it’s very good and effective to security the gate, I used this in all my installations and very happy with this product
Review: Part of my perfect gate opener - Until this was installed, we felt obliged to rush through the gate. To be honest, the first one didn’t work. Zach, our personal TOPENS customer service rep was always ready to answer. He was so responsive, day and night that I had to ask him if he was an Ai chatbot. He used regular language and assured me he was a real person. Anyway, he sent me a replacement right away and it works. It stops for anything in the laser line. Just another part that works perfectly on our perfect gate opener.

## Features

- Reliable Reversing Sensor - 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 effectively 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.
- Wide Compatibility - 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.
- Easy DIY Installation - 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.

### ⭐⭐⭐⭐⭐ Part of my perfect gate opener
*by B***B on May 13, 2026*

### ⭐⭐⭐⭐ Worked perfectly once installed but installation is a little tricky.
*by J***E on September 22, 2025*

The install was very simple and the product worked as designed.. Lining up the reflector was challenging because it is not visible light beam. Also is only active while gate is active. I held reflector close to source and slowly backed away keeping beam aligned. Also had remote in my hand to operate gate.
