## Description

This infrared photoelectric switch consists of a transmitter and receiver pair that detects objects at distances up to 1.5 m with a response time under 1 ms. The infrared beam provides stable detection regardless of ambient lighting, making it suitable for both indoor and outdoor use across a −20 °C to 65 °C operating range. Running on 9–24 V DC with an NPN three-wire output, the switch integrates easily into industrial control systems, Arduino or PLC projects, and robotics platforms for object detection, counting, and timing applications. Specifications Supply Voltage – 9–24 V DC Output Type – NPN, three-wire DC Output Current – 200 mA max Detection Distance – Up to 150 cm (1.5 m) Response Time – <1 ms Operating Frequency – 1000 Hz Operating Temperature – −20 °C to 65 °C Dimensions – 22.4 × 11.2 × 8.3 mm Shell Material – Polymer Wiring – Blue = GND, Brown = VCC, Black = signal output Ideal For Object detection and counting on production lines Gate and barrier sensing Robotics speed detection and lap timing Automation and security beam-break triggers Package Contents 1× Infrared transmitter module 1× Infrared receiver module
