Product Information for the Series
The MMS-308 series reed sensors, housed in robust threaded casings, allow for easy screw mounting and are characterized by exceptionally high reliability and flexibility. The series includes various contact forms: normally open (A), normally closed (B), and changeover (C). In addition to variants with low hysteresis, there are also special high-voltage versions designed for up to 1000 V DC. Various cable lengths, sensitivity ranges, and connector options ensure optimal adaptability to individual application conditions in demanding industrial environments.
