Description
The large metal Senator safety limit switches conform to EN 50041 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, 3 or 4 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 • Positive operation, forced disconnection of contacts • Snap-acting, slow make before break or slow break before make contact blocks • Contacts 1 N.C. + 1 N.O., 2 N.C. + 1 N.O. 3 N.C., 2 N.C. + 2 N.O., 3 N.C. + 1 N.O., or 4 N.C. • Conforms to EN 50041, EN 1088, EN 60947-5-1, EN 292 and EN 60204-1
➊ Conductive pollution occurs, or dry, non conductive pollution occurs which becomes conductive due to condensation.
