Leuze make HT25C/4P Polarized retro-reflective photoelectric sensor – 50134216

Leuze HT25C/4P – Diffuse Sensor with Background Suppression, Series 25C

The Leuze HT25C/4P is a diffuse sensor with background suppression designed for reliable object detection in industrial automation systems. Part of the Leuze Series 25C family, this sensor uses the diffuse reflection principle with background suppression to detect objects while minimizing unwanted reflections from background surfaces. Its long sensing range and fast response time make it suitable for conveyor systems, packaging machinery, and automated production lines. Engineers commonly use this sensor where stable detection across different object colors and materials is required.
