Cadet 3
Description
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 centres for ease of mounting.
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 (60mm or 2.36in).
Available with a variety of contact configurations, the Cadet 3 is
sealed to IP67. A blanking plug is supplied for the unused key entry.

➊ Conductive pollution occurs, or dry, non conductive pollution occur which
becomes conductive due to condensation.
Note: Lift-off guards require good alignment when using
tongue actuated interlock switches.
IMPORTANT: It must not be possible to lift the guard
without actuating the interlock. An interlock on either
side may be required.
