IP67 Waterproof Universal 10-30VDC Safety Retro-Reflective Photoelectric Beam Sensor for 12VDC and 24VDC Gate Opener, Garage Door Sensor Up to 40 Feet Sensing Range, Pre-Wired 6.6 Feet Cord

EDIT: This just paid for itself, and more. I installed it in August 2024. Today 1/1/2025, for the first time, it save me from closing my garage door onto the open hatch. If I could increase my rating to 6 stars, I would.I bought this Retro-Reflective Photoelectric Beam Sensor to add a SUV hatch sensor to my Genie garage door opener. The opener has the “Save-T-Beam” system where the Source and Sensor both have 2 wires and are connected in parallel to the opener. The new sensor requires connection to specific + and – DC voltage wires while the Safe-T-Beam system does not. So, I needed to use a voltmeter to identify the correct polarity. The attached picture shows how I wired it.How it works – The 12V DC is picked up using the Blue & Brown wires. The “OK” signal is disconnected if the new beam is interrupted by the SUV hatch. The original sensor at the floor operates just as it always has. I can’t guarantee it, but it seems that the same principle would work with other brands/types as well – you just need to understand where to interrupt the “OK” signal.

MUY BUENO PARA MI INVENTO

Very Happy with the results

The sensor on my Ramset gait opener took a dive and needed to be replaced. I contacted Ramset and they wanted $200 for a new sensor. I contacted a local distributor and they had to order one from Ramset. I found a generic version at Supreform at a reasonable price and figured if it doesn't integrate with my gate I'm only out 40 bucks. The wiring configuration was different from my original so I sent a picture of the controller board on my Ramset unit asking for, "an idiots guide to integration". Honestly, I did not even think I would get a response. What I did get was and overview of my current circuit board noting that I could not power the sensor from that board as is. They sent me a link to a power supply for 6 bucks with instuctions specific to my application...."idiot proof" This company is awesome, the customer service was outstanding.

I tried a cheaper ($20) one for my project but it did not properly sense a broken beam. It would see the reflection from my truck as if it were from the supplied reflector. True to the description I don’t have a false reflection issue with this one. The project you ask? This is mounted at bumper level on my garage door rail. When the beam breaks, a small led light bar illuminates. Once I am clear of the door, ie the vehicle is ‘in’, the light turns off. I am able to park just inside the garage door, not too deep in the garage and with no concern the closing door will hit my bumper.

I was skeptical but absolutely pleased with this product. The quality is top notch and my one question was answered by their support team via email in a couple hours. A+!!Not sure why the other reviewer only gave it one star—it’s not this company’s fault they don’t know what they need.It’s waterproof and easily covers my 24 foot driveway entrance. I rigged it to a siren on a relay timer and have the whole thing plugged into a smart switch (so I can schedule it’s operation). Easy as pie.

Stopped working after 8 weeks.

Diagram states infrared, but the beam is at least partly visible RED light. Beam is visible. This will help with beam aiming but I don't know if it will spook animals at night into taking another path to avoid the beam.
