Infrared Photoelectric Switch
Introduction
Infrared Photoelectric Switch is a compact long‑range optical detection solution designed for reliable object sensing in automation and robotics scenarios. The sensing system consists of a dedicated infrared transmitter and receiver pair capable of achieving detection distances up to 1.5 meters with a rapid response time below 1ms. Strong infrared penetration enables stable signal transmission even in challenging environmental conditions, supporting consistent detection accuracy. The compact industrial sensor module supports 12–24V DC power and integrates a durable polymer housing, making this optical detection unit suitable for machinery automation, robotics timing systems, and intelligent gate or counting applications.
Long‑Range Infrared Detection
This photoelectric sensing module uses a dedicated infrared emitter and receiver architecture to achieve stable object detection up to 150cm. Strong infrared penetration allows reliable signal transmission across varying lighting and environmental conditions. Fast response speed below 1ms supports high‑frequency sensing tasks such as motion detection, object counting, and rapid event triggering in automation workflows.
Compact Industrial Sensor Design
A miniature form factor measuring only 22.4 × 11.2 × 8.3mm allows installation inside narrow mechanical structures and embedded equipment. The polymer housing enhances durability while maintaining lightweight construction. This small optical detection unit integrates easily into robotics platforms, automated equipment frames, and embedded monitoring systems where installation space is limited.
Wide Voltage and Harsh Environment Compatibility
This industrial photoelectric detection device operates within a 12–24V DC power range and supports NPN three‑wire output for straightforward integration into automation control systems. Reliable performance across a temperature range of -20℃ to 65℃ enables both indoor and outdoor deployment. Such environmental tolerance makes the sensing component suitable for machinery automation, vehicle security systems, and industrial detection tasks.
Common deployment scenarios include industrial automation detection, robotics competition timing systems, automated gate monitoring, object counting equipment, and motion sensing mechanisms. The infrared sensing pair also supports speed measurement and trigger detection tasks in intelligent robotics projects and automated production environments.
