Product Details

Ferrogard 1, 2, 20 & 21 Non Contact Safety Switch

The Ferrogard FRS 1, 2, 20 and 21 are magnetically actuated non-contact safety switches which offer reliability and a high tolerance to misalignment. Designed to be installed on a guard door, the action of the magnetic actuator being removed from the switch opens the N.C. safety contacts therefore isolating the control power to the machines primary control element. Made from moulded ABS with a rectangular housing and sealed to IP67 (NEMA 6P), these non-contact switches are ideal for wet environments.

This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster.
Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime, and improving the machines overall efficiency. For more details, please go to the Guardlink brochure.
