The HT25C.S/4P is defined as Leuze< 10% up to 300 mm Black-white error diffuse sensor within the HT series of industrial Photoelectric Sensors. This HT25C.S/4P operates with 0–0.5 m sensing distance, 10–30 V DC supply, 1,500 Hz switching frequency, and IP66/IP67 protection. As part of the HT family, it uses diffuse reflection with background suppression and a small light spot configuration for stable short-range detection.
In packaging lines, conveyor systems, and assembly automation, the HT25C.S/4P supports reliable object detection at close distances. The red LED light source at 640 nm ensures consistent switching, while dual PNP outputs allow light and dark switching integration with PLC systems. The 4-wire, 2,000 mm cable simplifies panel wiring and control cabinet installation.
The Leuze HT25C.S/4P Photoelectric Sensor is structured for continuous industrial automation use. The HT25C.S/4P combines defined sensing range, 0.33 ms response time, and compact cubic housing to maintain stable signal output in temperature conditions from -40 to 60 °C. As a Leuze HT series model, it aligns with standardized electrical and optical specifications required in manufacturing environments.
