Leuze HT23/PDiffuse Sensor

The Leuze HT23/P Diffuse Sensor (50138488) is a compact diffuse reflection sensor with background suppression, designed for accurate object detection regardless of color or surface variations. With a sensing range of up to 400 mm and focused red LED (645 nm), it ensures reliable performance even in challenging conditions.

The sensor features a PNP output with dark switching, delivering precise detection with a fast 0.5 ms response time. Its multiturn potentiometer allows easy and accurate range adjustment between 15–400 mm. Built with a robust PC-ABS housing and IP67 protection, it withstands dust, moisture, and harsh industrial environments.

Operating on 10–30 V DC, it offers stable performance with low power consumption and excellent immunity to ambient influences.

Applications

Object detection in packaging and conveyors
Color-independent detection in automation lines
Small component positioning and sorting
General industrial sensing tasks

Technical Precautions

Adjust sensing distance using multiturn potentiometer
Ensure stable 10–30 V DC supply
Avoid exceeding 15% residual ripple
Install within -40°C to +60°C operating range
