FRS1 Datasheet, PDF (1/4 Pages) Allen-Bradley – Non contact Switches

Interlock Switches
Non contact Switches
Ferrogard 1, 2, 20 & 21
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.
Features
• Non contact actuation
• High tolerance to misalignment
• High switching current (up to 2A AC, 1A DC)
• Plastic rectangular housing (IP67)
• Cable or Quick Disconnect (QD) connections
