440P-CRPS11E Datasheet, PDF (1/6 Pages) Allen-Bradley – Safety Limit Switches
Position Interlock Switches
Safety Limit Switches
Small Plastic Senator
Description
The small plastic Senator safety limit switches conform to EN 50047
and have been developed to provide a range of options including
metal or plastic cases in various sizes, a choice of snap acting, slow
break/make with 2 or 3 contact configurations and a choice of
actuator heads.
The Senator range offers the option of rotating the head in 90°
increments before installation to allow ease of mounting.
Allen-Bradley/Guardmaster limit switches can be used in other
applications other than guard doors, for example on moving
machine beds, crane arms, lifts, elevators, etc.
Operation of these limit switches is achieved by the sliding action of
the guard or other moving object deflecting the plunger or lever. For
safety applications it is important that upon actuation, the guard or
other moving objects should not pass completely over the switch
and allow the plunger or lever to return to its original position.
Features
• Large selection of actuator heads

contact blocks
• Contacts 1 N.C. + 1 N.O., 2 N.C. + 1 N.O. 3 N.C.,
2 N.C. + 1 N.O.
• Conforms to EN 50047, EN 1088, EN 60947-5-1, EN 292 and
EN 60204-1
