Infrared Sensor Photocell for Gates, Security Gates, Motion Detection Beams, Garage Door Barriers, and Automatic Doors Features: - Consists of a transmitter and receiver; integrated amplifier produces an infrared beam. - Anti-interference design: narrow infrared beam minimizes disruption from ambient light. - Detection distance: 5–15 meters, even when installed at low height (20–40 cm above floor). - Self-detecting function: when the infrared beam is interrupted, automatic sliding doors stop closing and reverse fully. Doors reopen until the beam is restored. The detection function deactivates once the door is fully closed. Technical Specifications: - Technology: Infrared - Maximum detection range: 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 - Compatible with automatic sliding doors, roller doors, garage doors, and windows Installation Guidelines: - Recommended mounting height: ≥20 cm above floor - Minimum installation distance between transmitter and receiver: ≥2 meters - Mount units perpendicular to each other and aligned at the same horizontal level - Install receiver first, then transmitter - When the receiver’s indicator light turns off during alignment, secure the unit and complete wiring Note: - Due to high transmission power, placing the transmitter and receiver too close may cause no-response issues. Maintain at least 1 meter separation if this occurs. - If reduced sensitivity is observed at very short distances, removing the condensing lens from either unit may improve performance. - 180° rotation capability allows flexible alignment regardless of mounting orientation.
