The HT25C/6G-5000 is a Leuze 5,000 mm Cable length diffuse sensor designed for short to medium-range industrial detection. This Photoelectric Sensor provides 0–1.2 m sensing distance, operates at 10–30 V DC, and supports 1,000 Hz switching frequency with IP67 protection. As part of the HT series, it uses the diffuse reflection principle with background suppression for controlled object detection in industrial automation systems.
In conveyor systems, packaging lines, and assembly automation, the HT25C/6G-5000 enables stable switching for object presence and position control. The push-pull transistor outputs allow flexible light and dark switching logic in PLC circuits. With a 5,000 mm PUR cable and 4-wire configuration, integration into control panels and distributed systems remains straightforward.
The Leuze HT25C/6G-5000 Photoelectric Sensor combines defined optical sensing and electrical characteristics for continuous operation. As a Leuze HT series model, it supports 0.5 ms response time and reliable output behavior under -40 to 60 °C conditions. The plastic housing and IP66/IP67 protection make the HT25C/6G-5000 suitable for industrial automation environments requiring consistent performance.
