Description
Interlock
Switches
The Cadet 3 is a tongue (or key) operated safety interlock switch
designed to fit at the leading edge of sliding, hinged or lift-off guards.
With its dual entry slots and rotatable head, the versatile Cadet 3 can
offer up to eight different actuator entry options. The unique compact
housing (90.5 x 31 x 30.4mm (3.56 x 1.22 x 1.19in)) has industry
standard DIN 50047 fixing centers for ease of retrofitting.
Operation of the switch is achieved through the insertion of a specially
profiled stainless steel key that is permanently mounted to the guard
door. A semi-flexible key allows the Cadet 3 to be used on small radii
doors (150mm or 5.9in).
Available with a variety of contact configurations, the Cadet 3 is sealed
to IP67. A blanking plug is supplied for the unused key entry.
