Riko – SU-KP2

U-Shape Photo Sensor - 10mm Range Detection

Brand : Riko

Photoelectric Sensor (Thrubeam, Diffuse, Retro-reflective, BGS Type)

The RiKO SU-KP2 Series is a U-shape slot type photoelectric sensor designed for high-speed and precise object detection in compact industrial applications. With a fixed slot width, the sensor allows objects to pass through the detection gap, making it ideal for detecting small parts, labels, or moving components. It features a fast response speed up to 1 kHz and a narrow infrared beam, ensuring accurate and stable detection even for small targets.

Built for reliability, the SU-KP2 operates on a DC 12 to 24 V supply and supports NPN or PNP outputs with Light ON or Dark ON modes. The compact housing with IP64 protection ensures durability in typical industrial environments. Its simple installation and consistent performance make it suitable for packaging machinery, automation lines, and counting applications.
