Allen Bradley Guardmaster Safety Interlock Switch

The Allen Bradley Guardmaster elf tongue (or key) safety interlock switch has 2NC contacts. It has a voltage rating of 600VAC/DC. This is designed to fit at the leading edge of sliding, hinged, or lift-off guards. Its unique miniature housing (only 75 ´ 25 ´ 29mm) makes it the smallest interlock in the industry. It is designed for smaller machines such as printers, copiers, or domestic machinery that couldn't use safety interlocks due to space restrictions. With its dual entry slots and rotatable head, the device can offer up to 8 different actuator entry options. The user can operate the switch by inserting a specially profiled stainless steel key that is permanently mounted to the guard door. The semi-flexible key allows the Elf to be used on small radii doors (60mm or 2.36in).
Note:
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.
