Product Information for the Series
Reed contact-based magnetic sensors of the MMS 222 series, depending on the variant, with normally open, normally closed, or changeover contact in a compact cylindrical housing. The design is configured for clamp or plug-in mounting and can be flexibly installed in round bores. Thanks to different cable lengths, sensitivity ranges, and connector options, the sensors can be easily adapted to customer-specific requirements; variants with low hysteresis are also available.
