Riko – SN Series

Rectangular Inductive Proximity Sensor

Brand : Riko

The RiKO SN Series consists of rectangular inductive proximity sensors designed for non contact detection of metallic objects in industrial automation applications. These sensors use inductive sensing technology to detect metal targets reliably without physical contact, making them suitable for machinery, conveyors, positioning systems, and automated production lines. The series features a robust rectangular housing with LED indicators for clear operation status and easy installation using standard mounting structures.

The SN Series includes multiple models such as SND04, SN10, SN18, SN20, and SN28, which mainly differ in sensing distance and body size while maintaining the same core functionality and electrical characteristics. With built in short circuit and reverse polarity protection, along with IP66 protection, these sensors provide stable performance in harsh industrial environments. The wide range of sensing distances allows users to select the most suitable model based on installation space and detection requirements.
