The HT36I/4 is defined as Leuze plastic or PMMA lens cover diffuse sensor in the HT series of Photoelectric Sensors. The HT36I/4 operates with 0.01–2.5 m sensing distance, 250 Hz switching frequency, 2 ms response time, and IP67 protection. It belongs to the Leuze optical sensing range used in industrial automation systems requiring controlled background suppression detection.
In conveyors, packaging equipment, and automated assembly lines, the HT36I/4 provides stable object detection through diffuse reflection principle with background suppression. The focused infrared LED with rectangular light spot supports consistent sensing performance. Its PNP transistor output enables integration into 10–30 V DC control environments.
The Leuze HT36I/4 Photoelectric Sensor operates between -40 and 60 °C and uses a 2,000 mm PUR cable with 3-wire configuration. The HT36I/4 includes a plastic or PMMA lens cover and plastic housing designed for defined industrial use. As part of the Leuze HT series, it supports reliable sensing in industrial automation applications.
