Series characteristics
Reed contact-based magnetic sensors of the MMS 223 series are available with a choice of normally open, normally closed, or changeover contacts; one variant also offers a normally open contact with reduced hysteresis. Their cylindrical housing is designed for screw or adhesive mounting and can be easily integrated into round boreholes. The sensors can be actuated through non-ferromagnetic materials such as wood, plastic, or aluminum and are available with various cable lengths, sensitivity ranges, and connector options for customer-specific adaptations.
