Description

The ED series safety limit switches conform to EN 50047 and have been developed to provide a range of options including plastic

cases in various sizes, a choice of snap acting, slow break/make with 2 contact configurations and a choice of actuator heads.

The ED series offers the option of rotating the head in 90° increments before installation to allow ease of mounting.

Highly 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.
