Leuze HT5.1/P Diffuse Sensor

The Leuze HT5.1/P Diffuse Sensor (Part No. 50129402) is a compact diffuse reflection photoelectric sensor with background suppression, designed for precise and stable object detection in industrial environments.

It offers a detection range up to 400 mm with excellent performance across white, gray, and black objects, ensuring minimal black-white error (<15%). Equipped with a red LED light source (645 nm) and focused beam, it delivers accurate sensing even for small targets.

The sensor features a PNP output with dark switching, fast response time of 0.5 ms, and switching frequency of 1000 Hz, making it suitable for high-speed applications. Its rugged PC-ABS housing, IP67 protection, and wide operating temperature (-40°C to +60°C) ensure durability. With a 2-meter PUR cable and multiturn potentiometer, installation and adjustment are easy and reliable.

Applications

Conveyor belt object detection
Packaging and labeling machines
Small component detection
Material handling systems

Technical Precautions

Ensure proper alignment for accurate detection
Avoid direct exposure to strong ambient light
Maintain recommended sensing distance
Use stable 10–30 V DC power supply
