4 Technical information General characteristics The M3 series miniaturized limit switches are among the most compact on the market. Contact blocks are 1NO+1NC snap action, with positive opening of the NC contact. The switches are made of PA6 double insulated thermoplastic reinforced with fiberglass, class V2. The M3 series is equipped with M3, screw terminals. thermoplastic body metal actuators contacts type Zb gold plated contacts (on request) contact blocks with positive opening of the NC contact according to IEC EN e VD Galvanically separated contacts type Zb The NO and NC contacts are galvanically separated with positive opening: it is possibile to use the contacts independently.
