Leuze IPRK 92/4 L Polarized retro-reflective photoelectric sensor

The Leuze IPRK 92/4 L polarized retro-reflective photoelectric sensor delivers reliable object detection in slightly reflective environments with polarization-filtered illumination and background suppression. It features a compact sensor head, robust mounting options, and a standard 3-wire DC supply for straightforward integration into industrial automation networks. The device is designed for long-term reliability in manufacturing environments, with compatibility for standard conductor types and sizes and typical IP-rated enclosures suited for machine assemblies. Key electrical and mechanical characteristics include a 10–30 V DC supply range, low current draw during operation, and NPN/PNP output configurations to suit common control architectures. The polarized retro-reflective configuration minimizes false detections from ambient light and glossy backgrounds, enabling stable operation across varying lighting conditions. Mounting flexibility is supported by standard threaded holes and accessory options, enabling flush or upright installation on conveyors, machine frames, and GUIs where space is constrained. Typical applications include part presence detection on production lines, alignment checks, and feed-thru verification in packaging, robotics, and material handling systems. The device adheres to common industrial standards for photoelectric sensors and is compatible with standard cable glands and shielded conductors, ensuring reliable operation in industrial environments.
