The HT25C/4P is defined as Leuze 4 -wire Number of conductors diffuse sensor within the HT series of Photoelectric Sensors. The HT25C/4P operates with 0–1.2 m sensing distance, red LED 640 nm, 10–30 V DC supply, and IP66/IP67 protection. It belongs to the HT series and uses the diffuse reflection principle with background suppression in industrial automation environments.
In conveyors, packaging systems, and assembly stations, the HT25C/4P supports reliable object detection across variable surface conditions. The PNP light and dark switching outputs simplify integration with PLC inputs. The 4-wire configuration and 2,000 mm PUR cable allow flexible wiring in control panels and machine frames.
The Leuze HT25C/4P Photoelectric Sensor combines optical sensing and defined electrical characteristics for continuous operation. The HT25C/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 supports consistent detection performance in compact automation systems.
