Precise Infrared Beam Detection: Utilizes a split through-beam photoelectric design with focused LEDs (<5° emission angle). Detects any object interrupting the infrared beam with high sensitivity, fast response (<2ms), and stability across a 1-meter test distance. More reliable for specific zone detection than typical PIR motion sensors.
Key Technical Specifications: Operates at DC 5V (emitter: 20mA, receiver:10mA). Features NPN Normally Open output capable of directly driving relays (70mA max output current). Designed for indoor use with an operating range of -10°C to 60°C and a rated lifespan of 50,000 hours. Requires a 1K pull-up resistor for microcontroller I/O connection.
Simple Wiring & Output: Easy connection: Red wire to +5V, Black wire to Ground, Yellow/White wire to Signal output. Output transitions instantly upon beam interruption. Requires a 1KΩ pull-up resistor between +V and the signal wire for direct compatibility with logic inputs.
Versatile Hardware Compatibility: Designed for seamless integration with a wide range of controllers including relay modules, PLCs, and popular microcontrollers like STM32, K60, 51 series, and Arduino platforms. Ideal for counting, object detection, or security applications.
Ready-to-Use & Supported Package: Includes 2 pre-assembled sensor units (emitter & receiver pair) with 30cm attached wires (2.54mm terminal spacing - requires XH2.54 male plug). Backed by responsive customer support to assist with any integration questions or issues.
