Riko – SIA Series

Ring Inductive Proximity Sensor

Brand : Riko

The RiKO SIA Series consists of inductive ring proximity sensors designed for non contact detection of metallic objects passing through a circular sensing hole. The series is widely used in industrial automation applications such as wire monitoring, small part and bulk material counting, bolt detection, and component inspection. The ring-shaped sensing area allows precise detection without physical contact, providing stable operation in continuous production environments. (riko.com

The SIA Series spans small to large sensing diameters, including SIA05, SIA12, SIA15, SIA22, SIA30, SIA44, SIA63, and SIA100, allowing users to choose the appropriate model based on object size and process requirements. All sensors feature NPN or PNP outputs with normally open or normally closed options, and robust construction with IP65 protection. Lightweight and easy to install, the series ensures stable performance, low power consumption, and compatibility with standard power units, making it suitable for a wide range of industrial applications.
