Enhance the security and functionality of your access control system with this high-performance Infrared Photocell Sensor Pair, designed for reliable operation in various indoor and outdoor environments. Featuring advanced infrared technology, this sensor set is ideal for gate openers, parking lots, defence walls, doors, windows, garages, balconies, and other security-sensitive areas. Its durable construction and user-friendly installation make it the perfect addition to your security setup in schools, office buildings, homes, and more. Key Features: · Wide Application: Compatible with all gate openers and suitable for multiple security installations including access control systems, parking lots, residential yards, offices, schools, and garages. · Stable Infrared Signal Transmission: Equipped with a high-power infrared transmitter and receiver that create a stable, invisible infrared beam up to 20 meters (65 inches). The relay outputs a switch signal when the beam is interrupted, ensuring precise detection. · Water Resistant and UV Proof: Constructed with a fully sealed, egg-shaped cover made from durable PC material that is water-resistant and UV-proof, allowing it to operate reliably in harsh weather conditions. · Advanced Safety Protection: Utilizes cutting-edge security technology to provide multiple safety functions. The infrared photocell beam triggers gate stop or automatic reversal upon obstruction, protecting people and property. · Quick and Easy Installation: Simply install the sensor pair opposite each other to form an infrared detection area. When the beam is broken by an object or person, the sensor sends an alarm signal to the security system (alarm host not included).
