440H-R03074 Datasheet, PDF (1/3 Pages) Allen-Bradley – Hinge Switches

Interlock Switches
Hinge Switches
Rotacam
Description
A heavy-duty hinge actuated safety interlock switch, the Rotacam shaft
can be used as, or connected to, the existing hinge pin for direct
operation of the switch. Machine power is isolated when the guard
has been opened just 5°. For applications requiring a larger degree of
operation the internal cam can be adjusted from 5° to 11°.
Note: After adjustment, the cam must be secured in position with the
supplied cam locking pin to ensure optimal performance.
The Rotacam is available with two N.C. safety contacts and one N.O.
auxiliary contact. The switch includes the necessary safety related
functions, such as forced guided contacts and a tamper resistant
mechanism, allowing machinery to be safeguarded in compliance
with the machinery directive.
The die-cast housing is sealed to IP66 and features one M20 conduit
entry (1/2in NPT and connector style also available). Two different
shaft lengths of 30mm and 85mm can also be specified.
EX and Pneumatic styles of Rotacam are also available; see the
Explosion Proof section on page 16-1 for more information.
