The HT25C.S/2N is a Leuze red LED, protection circuit diffuse sensor configured for short-range object detection in industrial automation. This Photoelectric Sensor provides 0–0.5 m sensing distance, operates at 10–30 V DC, and supports 1,500 Hz switching frequency with IP67 protection. As part of the HT series, it uses diffuse reflection with background suppression and a small light spot design for controlled detection.
In conveyor systems, packaging equipment, and automated assembly lines, the HT25C.S/2N enables stable detection of small objects within limited sensing ranges. The red LED at 640 nm supports consistent switching performance, while dual NPN outputs allow light and dark switching configurations. The 4-wire, 2,000 mm cable simplifies integration into PLC-based control panels.
The Leuze HT25C.S/2N Photoelectric Sensor combines defined optical characteristics and electrical configuration for continuous industrial use. As a Leuze HT series model, it offers 0.33 ms response time and reliable switching under -40 to 60 °C operating conditions. The plastic housing with IP66/IP67 protection ensures suitability for industrial automation environments requiring stable signal output.
