Allen-Bradley Senator Limit Switches
The Senator is a large metal safety limit switch with the option of rotating the head in 90° increments before installation to allow ease of mounting. They can be used in applications other than guard doors, for example on moving machine beds, crane arms, lifts, elevators, etc.
Operation of the safety limit switch 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.
Positive operation, forced disconnection of contacts
Snap-acting, slow make before break or slow break before make contact blocks
Three actuator heads available: Roller Plunger, Short Lever or Spring Rod
Three contacts configurations available: 1NC/1NO, 2NC/2NO or 3NC/1NO
