Review: Excellent rear cable entry sensors - 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. Review: Great Photocells - Great Photocells very easy to install and align. I have a small problem activating the photocells so I contacted support@topens.com, and Bella resolved this problem very quickly and efficiently ## Features - 【Trustworthy Infrared Sensor】- The TOPENS TC102 Safety Photo Eye Beam Sensor employs infrared light for object detection, creating a safety barrier between the emitter and receiver. This photoelectric sensor identifies any movement interruption in the infrared beam, prompting the gate to stop or reverse automatically. It is strongly recommended to use the TC102 IR beam sensor with automatic gate opener system to ensure multiple protection & security. - 【Extensive Compatibility】 - Works with all the TOPENS gate openers, and compatible with most third party swing / sliding gate openers or garage door openers 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 12-24VDC or 12-24VAC power source. This infrared sensor is commonly employed in households, courtyards, farms, ranches, warehouses, and various commercial/industrial sites. - 【Ingenious Design】- The infrared photocell sensor consists of two components: an emitter generating an infrared light beam and a receiver detecting interruptions. This non-contact sensing technology provides high detection accuracy with a fast response. In addition, the infrared beam sensor is immune to strong light interference, such as sunlight and vehicle headlights. Weather resistant for all seasons of the year. - 【Simple DIY Installation】- Easily install by connecting both the receiver and the emitter to the automatic gate opener system. For optimal performance, mount the photocell sensor at least 20cm above the ground. Power on to determine the emitter position. The photocell status LED turns off indicating that the beam is aligned. Fix the emitter position when the status LED goes off. Ensure that there is no obstruction between the receiver and the emitter during alignment. - 【Exceptional Customer Support】- All the TOPENS products come with a 12-month war-ranty against defects, a 30-day worry-free exchange & return and lifetime tech support.

I have a small problem activating the photocells so I contacted support@topens.com, and Bella resolved this problem very quickly and efficiently ### ⭐⭐⭐⭐ It has a multitude of uses with a little thought and ingenuity. *by D***9 on 13 November 2022* 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. ## Frequently Bought Together - TOPENS 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 - TOPENS M12 Remote Control Key Fobs for Automatic Swing Sliding Gate Opener Garage Door Opener 4-Button Wireless Transmitter 2-Pack Security Gate Controller with Keychain - TOPENS ET24 Electric Gate Lock for 24VDC Automatic Swing Gate Opener Motor Gate Operator System Device Safe Security Outdoor Waterproof Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/343497093-topens-tc102-photocell-infrared-beam-sensor-safety-photoelectric-motion-detector](https://www.desertcart.vn/products/343497093-topens-tc102-photocell-infrared-beam-sensor-safety-photoelectric-motion-detector) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-14*
