A600/AC-15 (Ue) (Ie) N600/DC-13 (Ue) (Ie) 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. Thermal Current (lth) Min Current Typical Contact Resistance Rtd.

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 BBM/MBB Actuator Flat 90° 3 N.C. — — GD2 Metal Alignment Guide with SemiFlex Actuator — Flat 90° BBM GD2 Metal Alignment Guide with SemiFlex Actuator — Flat 90° MBB GD2 Metal Alignment Guide with SemiFlex Actuator — M16 Conduit 440K-C21096 440K-C21097 — 440K-C21070 440K-C21098 440K-C21061 — 440K-C21055 440K-C21052 440K-C21065 — 440K-C21080 M16 Conduit/ 1/2in Adaptor 440K-C21048 440K-C21057 440K-C21062 — 440K-C21050 440K-C21058 440K-C21074 — 440K-C21093 440K-C21094 440K-C21095 — Quick Disconnect 440K-C21090 440K-C21091 440K-C21092 — 440K-C21054 440K-C21067 440K-C21088 — 440K-C21060 440K-C21068 440K-C21089 — 2 N.C. 1 N.O.
