440K Guardmaster Trojan 5 Tongue Interlock Elf™

The Elf is a tongue-operated (or key-operated) safety interlock
switch designed to fit at the leading edge of sliding, hinged or lift-off
guards. The Elf’s unique miniature housing (only 75 x 25 x 29 mm)
makes it the smallest interlock currently available. It is designed for
smaller machines such as printers, copiers and domestic machinery
which, until now, have been unable to use safety interlocks due to
space restrictions. With its dual entry slots and rotatable head, the
versatile Elf can offer up to eight different actuator entry options.
Operation of the switch is achieved through the insertion of 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 (60 mm or 2.36 in).
The Elf is available with a variety of contact configurations, conduit
entry types and connectors. It is sealed to IP67 (watertight and
dustproof). A blanking plug is supplied for the unused key entry.
