Diffuse Reflection Photoelectric Switch (0–7m) is an industrial-grade infrared detection device designed for reliable non-contact object sensing. Using diffuse reflection infrared technology, the sensing unit detects opaque objects within a typical range of 0–7 meters, with test conditions demonstrating even longer detection capability. The wide 6–36V operating voltage supports integration into diverse control systems and automation equipment. Durable ABS housing, integrated status indicator, and onboard sensitivity adjustment enable stable deployment in industrial automation, safety monitoring, and intelligent equipment where dependable long-range object detection is required.

Long-Range Diffuse Infrared Detection
This infrared photoelectric sensing module detects any opaque object within a standard range of 0–700 cm. Diffuse reflection technology allows transmitted infrared light to bounce back from a target surface and trigger detection without requiring a reflector. Stable detection performance enables reliable use in environments such as automated gates, vehicle detection systems, and industrial safety monitoring. Under optimized conditions, testing indicates sensing distances may exceed 7 meters, expanding operational flexibility for large-area detection scenarios.
Adjustable Sensitivity with Real-Time Status Indication
An integrated adjustment knob allows precise control of detection distance. Clockwise rotation increases sensitivity and detection range, while counterclockwise rotation reduces it for short-range operation. A built-in signal indicator provides immediate visual feedback on sensing status, helping technicians quickly calibrate and monitor performance during installation or operation. This convenient adjustment mechanism improves adaptability for changing detection environments and diverse object sizes.
Industrial Protection and Durable Construction
Designed for demanding environments, the infrared detection unit features IP67 waterproof capability combined with protective circuitry including polarity protection and short-circuit protection. The rugged ABS enclosure enhances durability against mechanical stress and environmental exposure. A 2‑meter power cable simplifies installation in large equipment or outdoor monitoring systems, making the sensing device suitable for automation infrastructure and long-term deployment.
This long‑range infrared sensing solution is widely used in automatic car washing systems, security detection installations, automatic access control barriers, and intelligent sensing furniture. Reliable object detection and robust protection features make the module suitable for industrial automation, smart infrastructure, and safety monitoring applications requiring stable long‑distance sensing.
