Garage Door Sensors OEM Replacement for Genie/Overhead Garage Door sensors, GSTB-R STB-BL Garage Sensor for Genie Garage Door Openers Manufactured After 1993.(Receiving&Sending)

Perfect Compatibility Designed for Genie and Overhead brand garage door openers manufactured after 1993. Replaces GSTBR, STBBL, and 37220R safety sensors. Why select this garage door sensor? When family members or pets accidentally approach the garage door as it is descending, standard sensors may respond slowly. However, the patented safety beam can activate the emergency stop and reverse ascent action within 0.1 seconds, helping to avoid injuries or damage to items. The sensor itself does not contain an installation bracket. Matching brackets are available separately.
High-quality materials: The garage door safety sensor is constructed from high-strength ABS engineering plastic, which offers impact resistance and anti-aging properties. Each sensor has passed rigorous waterproof, dustproof, and weather resistance testing, and can function reliably in extreme environments from -40 to 60. Even during heavy rain or intense sunlight, the sensor replacement operates dependably.
Installation and inspection steps: 1. First, disconnect the power supply. Determine the sensor's installation position and ensure the sensor height is consistent. The probes must be directly aligned. 2. When connecting the sensor wires to the corresponding interface on the garage door controller, identify the positive and negative poles and do not connect them in reverse. When the sensor indicator light is illuminated, it signifies normal operation. Please note that this product does not include an installation bracket. If you require a matching bracket, please purchase the Sensor + Bracket Set to prevent installation issues upon arrival
