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.

Features

•Compact size

• Ideal for small, light weight guards

• Contacts, 2 N.C. + 1 N.O. or 3 N.C.

•Sealed to IP67

• Eight possible actuator entry points, easy to install

• Industry standard fixing centres to DIN 50047

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.
