Product Details
✓Perfect Compatibility – Fits Genie/Overhead garage door openers manufactured after 1993; replaces GSTB‑R, STB‑BL, 37220R safety sensors.
✓Why choose our garage door sensor? When your family members or pets accidentally approach the garage door as it is descending, ordinary sensors may react slowly. However, our patented safety beam can trigger the "emergency stop + reverse ascent" action within 0.1 seconds, completely preventing injuries or damage to items, and completely eliminating safety hazards. The garage door sensor itself does not include an installation bracket. We also sell installation brackets separately.
✓High-quality materials: The garage door safety sensor is made of high-strength ABS engineering plastic, which possesses shock resistance and anti-aging properties. Each sensor has undergone strict waterproof, dustproof and weather resistance tests, and can operate stably in extreme environments ranging from -40℃ to 60℃. Even in the case of heavy rain or intense sunlight, the garage door sensor replacement can work reliably.
✓Installation and inspection steps for garage doors: First, the power supply needs to be cut off. Determine the installation position of the sensor and ensure that the sensor height is uniform. The probe must be directly aligned. 2. When connecting the sensor wires to the corresponding interface of the garage door controller, distinguish the positive and negative poles and do not connect them in reverse. When the sensor indicator light is on, it indicates that everything is normal.
✓Shopping with no worries： Please note that this product does not come with an installation bracket. If you need a matching bracket, please purchase the "Sensor + Bracket Set". Avoid the situation where the product cannot be installed upon arrival. The garage door sensor offers a 3-year warranty. Even if it exceeds the official Amazon return period, return and exchange services are still available. Any usage or installation issues will be responded to and resolved within 12 hours.
