Leuze RK 701/0.8.1 Energetic diffuse sensor

Leuze RK 701/0.8.1 Energetic diffuse sensor is a compact, 3-wire DC photoelectric sensor designed for reliable presence detection based on reflected light from target surfaces. It combines a fixed sensing distance with robust housing and straightforward teach-in operation, suitable for inline automation, object detection on conveyors, and packaging lines. The sensor operates from a standard DC supply (10–30 V DC) with either NPN or PNP output configurations and an exportable current budget typically in the low hundreds of milliamperes, depending on load. The diffuse mode detects a target within a nominal range around 0.8 meters, with a stable output indicating object presence. A bright LED indicator provides real-time status, and the unit offers robust IP65/IP67-type sealing for use in industrial environments. The RK 701/0.8.1 is compatible with common conductor sizes and wiring schemes: 3-wire DC with brown (V+), blue (0 V), and black (output) conductors, suitable for either sourcing or sinking logic depending on variant. Mechanical and mounting details are compatible with standard DIN rail or panel mounting, featuring adjustable mounting options and a compact form factor to fit tight spaces along conveyors and machine frames. With standard electrical isolation and protection against short-circuits and reverse polarity, the sensor is suitable for demanding manufacturing environments. Typical applications include part presence detection on conveyors, automated packaging lines, and edge-detection tasks where ambient light is controlled and target reflectivity is suitable for diffuse sensing. The device aligns with common CE safety and electrical compatibility requirements; precise approvals should be verified in the datasheet for region-specific compliance.
