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.
