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 contact which is intended for the
isolation of control power to a machine primary control element.
The FRS 6, 9 and 10 sensors and actuators incorporate slim
housings to accommodate narrow mounting areas. They are
environmentally sealed to IP67 (NEMA6P), which makes them ideal
for wet environments. These Ferrogard switches have two active
sensing faces allowing more flexible mounting options.
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.
