Leuze make HT23/2 Diffuse sensor with background suppression – 50138442

Leuze HT23/2 – Diffuse Sensor with Background Suppression, Series 23

The Leuze HT23/2 is a diffuse sensor with background suppression designed for precise object detection in industrial automation applications. Part of the Leuze Series 23 family, this sensor uses the diffuse reflection principle with background suppression to detect objects while reducing interference from reflective or changing background surfaces. The focused beam path and fixed focal distance improve detection stability for small objects and fast-moving applications. Engineers commonly use this sensor in conveyor systems, packaging machinery, and automated production equipment where fast switching and compact installation are important.
