Series characteristics
Product Information for the Series
Reed contact-based magnetic sensors of the MMS 204 series combine normally open, normally closed, or changeover contacts in a compact cylindrical housing for clamp or plug mounting. The sensors can be actuated through non-ferromagnetic materials such as wood, plastic, or aluminum and are flexibly adaptable to customer-specific requirements thanks to various cable lengths, sensitivity levels, and connection options.
