Active Photoelectric Single Infrared Beam Sensor Barrier Detector Alarm System Features: This is an upgraded version of a single-beam sensor featuring the latest LED indicator light and more SMT components compared to older three-light, hand-assembled models. It offers improved stability and reliability. When the infrared beam is interrupted, the relay outputs a switch signal. This device is suitable for use with parking barriers, pedestrian gates, and vehicle gates as a body detection sensor. It can also be used for anti-intrusion detection on windows, doors, and passageways. 1. Operational distance ranges from 2 to 15 meters. For short-distance applications, the infrared beam may be too strong to interrupt reliably; removing the lens cover resolves this issue. 2. Upon beam interruption, the relay outputs a dry-contact switch signal (no voltage). 3. Equipped with both normally open (N/O) and normally closed (N/C) switching outputs. 4. Compatible with access control systems, parking barriers, and alarm systems. 5. Operates on a 12V DC power supply. Specifications: 1. Single-beam infrared sensor with modern LED indicator light. 2. Anti-glare capability up to 50,000 lux to minimize interference from ambient light or vehicle headlights. 3. Sealed housing design provides resistance to rain, fog, dust, and insects. Features automatic gain control (AGC) to maintain optimal detection sensitivity under varying weather conditions. 4. High immunity to radio-frequency interference (RFI) and electromagnetic interference (EMI). 5. High-power infrared transmitter with 90% sensitivity margin. 6. High-power infrared receiver tube utilizing low-power processing technology. 7. Adjustable beam interruption timing for enhanced flexibility and adaptability. 8. Professional optical housing designed to prevent signal interference. Package Includes: 2 x Infrared Beam Sensors
