Interlock Switches Non contact Switches Ferrogard 1, 2, 20 & 21 Specifications Description The Ferrogard range of magnetically actuated safety switches offers Non contact reliability together with tolerance to misalignment. 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.

Fuse Externally Interlock Switches Non contact Switches Ferrogard 1, 2, 20 & 21 Application Details Operating Principle Encapsulated in the Ferrogard is a unique high power industrial reed, capable of switching up to 15A. The need switch is de-rated by a non resettable overload protection fuse. On presenting the actuator to the switch, the high intensity magnetic field from the actuator causes the contacts to close. On removing the actuator (opening the door), the safety contacts open. Typical Operating Curve 10 (0.39) When the actuator is aligned with the switch, the sensing distance is 10mm (0.39.) As the amount of misalignment increases, the sensing distance decreases. Beyond 4mm (0.16), the switch will not actuate in the presence of the actuator. 4 (0.16) 4 (0.16) Misalignment tolerance on nonferrous materials 3-45
