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.

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.
