The HT25C.XL/4P is a Leuze 0–20 mA open-circuit current diffuse sensor configured for industrial automation applications. This Photoelectric Sensor provides 0–0.6 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 applies the diffuse reflection principle with background suppression and extra long light spot design.
In conveyors, packaging systems, and automated assembly lines, the HT25C.XL/4P enables stable short-range detection across wider object areas. The divergent beam path and rectangular light spot support consistent sensing performance. With dual PNP outputs and 2,000 mm cable, the sensor integrates efficiently into PLC-based industrial control systems.
The Leuze HT25C.XL/4P Photoelectric Sensor combines defined optical parameters and electrical configuration for continuous industrial use. As a Leuze HT series model, it integrates 0.5 ms response time and background suppression for reliable signal switching. With operating temperature range of -40 to 60 °C and IP66/IP67 protection, this model remains suitable for industrial automation environments.
