Leuze PRK5BPP.1/4X-M8 Polarized retro-reflective photoelectric sensor

Leuze PRK5BPP.1/4X-M8 is a polarized retro-reflective photoelectric sensor designed for precise object detection in challenging backgrounds. It features a compact M8 sensor body with polarized light to improve reliability against color and contrast variations, making it suitable for packaging, conveyor, and automation lines. Electrical characteristics include a robust supply range, typically 10–30 V DC, with protection against short-circuit and reverse polarity. The device supports standard 3-wire or 4-wire configurations and provides PNP/NPN switching outputs depending on variant, suitable for direct interfacing with PLCs and modern I/O systems. Mounting options commonly include snap-in or bracket mounting for quick alignment, with adjustable sensing distance appropriate for small to mid-size targets. Typical applications include presence/absence detection on conveyors, label or cap inspection, and alignment sensing in manufacturing cells. The sensor adheres to general electro-mechanical standards for industrial automation and is designed for reliable operation in industrial environments with IP-rated housing and standard M8 connector style.
