Description
The RLK31-8-2500-IR-31-115 is a high-performance diffuse mode photoelectric sensor designed for reliable object detection in industrial automation environments. Utilizing infrared light technology with background suppression, this sensor provides precise detection of objects regardless of surface color or reflectivity variations. With a compact cylindrical housing (M18 form factor) and IP67 protection rating, it is suitable for harsh industrial applications including packaging machinery, material handling systems, and automated production lines. The sensor features a 2.5m sensing range, adjustable sensitivity via potentiometer, and both light/dark operate modes for flexible integration.
