Series characteristics
Reed contact-based magnetic sensors of the MMS 224 series are available as normally open, normally closed, or changeover contacts and are housed in a robust cylindrical housing that can be clamped or plugged in, as required. They can be actuated through non-ferromagnetic materials and are available with various cable lengths, sensitivity ranges, and connection variants. In addition to standard versions, variants with low hysteresis and a high-voltage version up to 1000 V DC are available, allowing the series to be flexibly adapted to different industrial requirements.
