Haake Safety Edge

The sensor part of the safety edge is positioned directly behind the front portion of the rubber profile. Separation of the contact position does not rely on a bending of the contact chain, but on the re-direction of the external radial forces to internal axial forces. Actuation will commence at low actuating forces and after a very short response travel, providing a fast response time. The full remaining height of the rubber profile is available as an over-travel. In particular with regard to the prevention of injuries, large over-travels are of enormous importance for a safety sensitive edge.

Either electrically operating devices to the contact-make principle (two conductive strips or layers are brought together when the safety mat is operated), or opto-electronic systems (a light beam is interrupted) are available on the market. Such configurations need a special evaluator for transforming and processing the output signal.


Because of the rotationally symmetrical design of the contact chain, our edges can theoretically be operated from any direction, that is, their sensitive range covers 360.
