They are designed to be installed so that when a guard door is opened, the action of the magnetic actuator being removed from the switch opens the N.C. safety contacts which are intended for the isolation of control power to a machine primary control element. The FRS1, FRS2, FRS20, FRS21 are rectangular housings. Sealed to IP67 (NEMA6P), these Ferrogards are ideal for wet environments. Unlike some magnetic switches the Ferrogards have protected safety contacts to help ensure that they do not fail to danger. In addition, some versions have independent auxiliary signal contacts to indicate the guard condition. All Ferrogards have internal non-resettable overload protection on the safety contact. They should be protected by an external fuse rated as shown in the Specifications table. AC 250VAC 2A max DC 24VDC 1A max Safety Contact External Fusing AC
