Description
IR18S series inductive proximity sensors are compact, rectangular inductive sensors designed for precise, non-contact detection of metallic objects in space-constrained industrial applications. Using electromagnetic induction, IR18S sensors deliver reliable switching, high repeatability, and long service life. Their slim rectangular housing makes them ideal for automation panels, packaging machines, assembly lines, conveyors, and OEM equipment where cylindrical sensors are difficult to mount.
