1 / 4 page 3-52 Interlock Switches Non contact Switches Ferrogard GS1 & GS2 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 GS1 and GS2 are designed for heavy duty applications. The GS1 is housed in a stainless steel or brass housing. The GS2 offers the same characteristic as the GS1, but in an Ex housing for hazardous locations. Unlike some magnetic switches the Ferrogards have protected safety contacts to help ensure that they do not fail to danger. 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. See the Explosion Proof section on page 16-1 for more information on the EX version of the Ferrogard GS2.
