The HT25CI/4P is defined as Leuze PNP Light/dark switching diffuse sensor within the HT series of industrial Photoelectric Sensors. This HT25CI/4P operates with 0–1.3 m sensing distance, infrared LED 850 nm, 10–30 V DC supply, and IP66/IP67 protection. It belongs to the HT series and supports diffuse reflection principle with background suppression for industrial automation systems.
In conveyors, packaging lines, and assembly stations, the HT25CI/4P provides stable object detection across varying surface conditions. The PNP light and dark switching outputs allow flexible PLC integration, while the 2,000 mm PUR cable supports panel and field wiring layouts. The infrared LED improves detection consistency in environments with visible light interference.
The Leuze HT25CI/4P Photoelectric Sensor combines defined optical performance with electrical compatibility for continuous machine operation. The HT25CI/4P maintains 1,000 Hz switching frequency and 0.5 ms response time within -40 to 60 °C ambient conditions. As part of the Leuze HT series, it aligns with compact sensor requirements in industrial automation.
