## Description

Product Description Works with All the TOPENS Gate Openers TOPENS TC102 Photo Eye Beam Sensor is an outdoor photoelectric sensor with rapid response. It is strongly recommended to use the TC102 photo eye beam sensor with automatic gate opener system to ensure multiple protection & security. Why Choose TOPENS? Founded in 1998, TOPENS is one of the UK's well-known and trusted consumer brands in gate automation industry. We have a knowledgeable, talented team of technicians to assist you with all of your questions and troubleshooting. TOPENS TC102 PHOTO EYE BEAM SENSOR - HIGHLIGHTS Reliable Reversing Sensor The emitter is designed to generate an infrared light beam. The receiver is used to detect any interruptions. TC102 creates a safety barrier that identifies any movement between the emitter and receiver. Once the infrared beam is blocked, it perfectly makes the gate stop or reverse automatically. Commonly used for the household, courtyard, farm, ranch, warehouse and other commercial / industrial sites. IP44 Waterproof for Outdoor Use The infrared ray of TC102 is immune to strong light interference, such as sunlight and vehicle headlights. At the same time, most of the family light also will not affect the infrared sensor of TC102. Weather resistant for all seasons of the year. Working Temperature: -20℃~ +50℃ Simple Wire Connection Connect both the receiver and the emitter to the gate opener system. Please refer to the corresponding User Manual for the correct wire connection. Connect the emitter to the gate operator system or receiver with a 2 x 0.3mm² cable . Connect the receiver to the gate operator system with a 4 x 0.3mm² cable . Cables are required but NOT included. It is highly recommended to install the emitter 3m to 14m away from the receiver. Easy DIY Installation Power on to determine the emitter position. The photocell status LED turns off indicating that the beam is aligned. Ensure that there is no obstruction between the receiver and the emitter during alignment. It is suggested to mount the photocell sensor at least 20cm above the ground. The distance between the sensor and the control board should be within 20m . One TC102 photocell sensor can only work for one gate operator, while one gate operator can connect two TC102 at most.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Photocells
*by G***G on 16 April 2026*

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

### ⭐⭐⭐⭐⭐ Working as intended.
*by F***D on 13 May 2026*

I purchased these in addition to the photocell that came with my motor kit. This was so that I could have a pair inside and outside the gates. All fitted and working perfectly.

### ⭐⭐⭐⭐⭐ Excellent rear cable entry sensors
*by E***I on 17 April 2025*

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.
