About this item

  • 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.

Ordered the reflector because I originally installed the RK1100T with a different reflector. They didn't work well in the sun. Got the TRF# and it works great! Easy to Install as well

Well this stupid TRF3 safety reflective hate opener when wired up as pert topensanuals works the wrong way round with beam aligned won't open or close break the beam & it will let you open & close. Burnt out my gates main board. Gate wouldn't stop hit the stopper & burnt their board,Topens reached out to me & sent me another one free of charge. I fitted it & wired it up & it is working like it should. I have changed my rating to 5 star would give them 10 if was possible. Chelsey from Topens customer service was fantastic & delt with the issue very professionally. They certainly stand by their product & warranty I would highly recommend their products.

I purchased this sensor as a safety measure in case a person or car entered the field of view while closing. The unit works seamlessly and functions to prevent inadvertant gate closure on objects entering the swing radius of the gate while closing. I recommend aligning the transmitter/target during darkness such that you can visibly see the light beam and adjust the target.

Installed and wired as directed....once installed, the opener drops to a crawl speed.

This was super easy to install and provides safety for the gate. I would highly recommend it for all Topens gates

I installed this with a Topens CK700 sliding gate opener and it works as expected. The wiring instructions weren't great but if you keep in mind it's just a SPDT switch than you could figure it out (I attached two photos of my wiring for reference). I placed the sensor on my gate post and the reflector on the other side of my driveway 15' away. It works as expected and reverse my gate as soon as anything moved across the sensor. You do have to provide your own wiring. I had a 20AWG 3 lead consolidated wire from a previous project that worked great. It's easier to set up than the cheaper two piece sensors and I consider this a safety requirement for any type of automated door.

Very convenient and helpful solution to obstacle avoidance for a sliding electronic gate! Quick to install with an eagle automated door opener. Do the alignment with the reflector in late evening or night as the beam is clearly visible. Wiring instructions from Topen that come with the product are clear, but to understand how to wire it with the gate opener, I had to connect with their tech support, who were extremely responsive and explained how to connect NO #4 output from this to reverse loop global input on the board and how to setup the pins. Tech support 5 stars here are for Eagle tech support. But overall, combined result was a very smooth, and uneventful installation that resulted in the exact functionality that was desired!

things to know, were not even mentioned in the instructions. number 1 is how to adjust the beam with the three tiny screws on the spring loaded printed wiring board, number 2 is that the spring strength varies markedly between units, number 3 is that the beam projection can be most easily seen at dusk to significantly aid in aligning the reflector disk. number 4, the description should have made clear that no wires are included which I had to pay extra for and delayed the installation. number 5, the toll free support number is worthless since you can’t directly speak to anyone, number 6, and most importantly, the design should have allowed for tuning in the beam direction AFTER the plastic lens is secured. It is a real pain to iteratively adjust the beam direction since is easily deflected off the mark during the plastic lens install.

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.

compre estos sensores para tener todo de la marca topens pero fallan mucho cuando les da la luz del sol, en hora en el que el sol esta bajo funcionan perfectamente pero cuando esta alto se la pasan activándose y no dejan que la reja cierre.tengo dos instalaciones distintas y en las dos falla incluso compre nuevos sensores pensando que podrían estar defectuosos pero aun así siguen fallando.
