Safety Products Supplement Cadet 3 Specifications Standards Approvals Compact Tongue Operated Safety Interlock Switch 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. Features • • • • • • Compact size Ideal for small, light weight guards Contacts, 2 N.C. + 1 N.O. or 3 N.C.
