Riko – SU30-KP2 / SU30-KP2K

U-Shaped Photo Sensor - 30mm Range Detection

Brand : Riko

The Riko SU30‑KP2 and SU30‑KP2K U‑shape photoelectric sensors are part of Riko’s SU30 family of wide‑slot optical sensors. They feature a 30 mm slot opening that allows objects to pass through for reliable detection, making them ideal for conveyor part sensing, position verification, and material presence applications in industrial automation systems. Both models use an infrared LED emitter and deliver a fast response frequency up to 1000 Hz, ensuring accurate detection of opaque objects in high‑speed environments.

The two variants differ mainly in their wiring methods and housing weight, offering compatible performance with flexibility in installation. The SU30‑KP2 model comes with a pre‑wired cable, while the SU30‑KP2K uses an M12 plug‑in connector type, facilitating easier connection and replacement in machine settings. Both sensors feature dual indicators for power and sensing status, as well as robust industrial protection and vibration/shock resistance.
