Actuators for Safety Switches

On actuation, the switching element and actuator are either brought together or separated. Using increased extraction force on the actuator, BERNSTEIN safety switches prevent the safety door from being opened unintentionally.

Standard actuator ACS-1
Proven standard model among the actuators. Minimum actuating radius 800 mm.


Flexible actuator ACF-1
Designed to compensate for a slight vertical/horizontal offset. Minimum actuating radius 400 mm.
The actuator can be aligned with the aperture of the SLC head opening by pressing it in and turning it 90°.


Transverse actuator ACC-1
Actuator for vertical / horizontal mounting. Minimum actuating radius 600 mm.

Standard actuator A1
Actuators for standard applications with a minimum actuating radius of 400 mm.

Hinged Actuator A2
Actuators for applications with a minimum actuating radius of 150 mm. Repositioning of spring-mounted actuator by 4 x 90° in not mounted state possible.

Hinged Actuator A3 with dust cap
Actuators for applications where the minimum actuating radius is at least 400 mm and where the actuator hole must be protected from fine dust.
Repositioning of spring-mounted actuator by 4 x 90° in not mounted state possible.

Flexible actuator A4
Actuators for applications with a minimum actuating radius of 350 mm.
Repositioning of spring-mounted actuator by 4 x 90° in not mounted state possible.

Transverse actuator A7
Actuator with mounting flange for standard applications with a minimum actuating radius of 400 mm.
