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. Min Current 5V 5mA DC Typical Contact Resistance 5mΩ Rtd. Insulation Voltage (Ui) 500V 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. Features • • • • • • Compact size Ideal for small, light weight guards Contacts, 2 N.C. + 1 N.O. or 3 N.C.

Applications 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. 3-6 Interlock Switches Tongue Switches Cadet 3 Product Selection Catalogue Number Safety Contacts Auxiliary Contacts 3 N.C. — BBM/MBB — BBM 2 N.C.
