Infrared Sensor Photocell for Gates, Security Gates, Motion Detection, Beam Detector, Garage Door Barrier, and Automatic Door Systems Features: - Consists of a transmitter and receiver; integrated amplifier produces an infrared beam. - Anti-interference design: narrow infrared beam minimizes interference from ambient light. - Detection distance: 5–15 meters, even when installed at low height (20–40 cm from the floor). - Self-detecting function: when the infrared beam is interrupted, the door stops closing and reverses fully. The door reopens until the beam is restored. The detection beam is deactivated when the door is fully closed. Technical Specifications: - Technology: Infrared - Detection range: up to 15 m (range may reduce by up to 30% in adverse weather such as rain or dust) - Infrared frequency: 1.92 kHz - Power supply: 12–24 V DC/AC - Wavelength: 940 nm - Current draw: Receiver – 15 mA, Transmitter – 30 mA - Operating temperature: –10°C to +70°C - Relay contact rating: max. 1 A / 36 V - Dimensions: 100 × 40 × 35 mm Applications: - Automatic sliding doors, roll-up doors, garage doors, windows, and gate openers. Installation Notes: - Recommended installation height: ≥20 cm above floor level. - Minimum installation distance between transmitter and receiver: ≥2 meters. - Mount units at the same horizontal level, aligned perpendicularly to the protected area. - Install receiver first, then transmitter. Confirm proper alignment by verifying the status indicator (e.g., “OFF” LED extinguishes upon correct beam reception), then secure and connect wiring. Important Safety & Operation Notes: - Due to high output power, ensure minimum separation between transmitter and receiver. If no response occurs, increase spacing by at least 1 meter and retest. - If reduced sensitivity is observed during close-range installation, removing the condensing lens from either unit may improve responsiveness. - 180° rotation capability allows flexible alignment regardless of mounting orientation.
