Inductive ring sensors

Dietz inductive ring sensors reliably detect small metallic parts inside the ring. Easy installation, short response times, high resolution, and adjustable pulse duration enable universal use in a wide range of applications.

Thanks to optimized shielding against interference, the sensors can be mounted very close to each other or to machine parts. Two different operating principles are available.

Ring sensors with  static  switching behavior detect fast-moving, very slow-moving, or permanently moving metallic objects inside the ring, e.g., for fill level control. Ring sensors with  dynamic  switching behavior detect even the smallest objects at the highest part speeds, e.g., pneumatically conveyed springs. Very slow-moving objects or objects permanently moving inside the ring are not detected by these sensors.

The dynamic function allows for automatic adaptation to changing environmental conditions such as metal abrasion, thus increasing operational reliability. Furthermore, special ring sensors with analog outputs are available. These are particularly suitable for differentiating object sizes, part separation, or thickness measurement.
