The HT25CL2/4P is a Leuze elliptic type of light spot geometry diffuse sensor designed for industrial automation. This Photoelectric Sensor provides 0.005–0.8 m sensing distance, operates at 10–30 V DC, and supports 2,500 Hz switching frequency with IP67 protection. As part of the HT series, it applies the diffuse reflection principle with collimated laser beam for precise object detection.
In conveyors, packaging lines, and automated assembly systems, the HT25CL2/4P enables accurate short-range sensing. The 650 nm red laser with elliptic light spot geometry supports stable detection of small or defined targets. With dual PNP outputs for light and dark switching and a 2,000 mm cable, the sensor integrates easily into PLC-based control architectures.
The Leuze HT25CL2/4P Photoelectric Sensor combines defined optical alignment and electrical configuration for continuous industrial use. As a Leuze HT series model, it integrates 0.2 ms response time and background suppression for reliable switching. With operating temperature range of -40 to 60 °C and IP66/IP67 protection, this model remains suitable for industrial automation environments.
