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.
A special control unit is not required, since the contact chain is composed of electro-mechanical break contacts, the signal of which can immediately be processed. In addition to cost saving, any expensive connection and wiring actions are unnecessary. 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°. safety edge aluminium profile haake contact chain machinery directive safety edge emergency stop switch emergency stop button safety edge PU foam safety edge category 3 safety edge rubber profile safety edge EN 954-1 HSC safety edge safety edge category 4 process engineering safety edge safety edge DIN ISO contact edge pressure edge stop edge rubber edge closing edge protection for closing edges shearing edges crushing edges protection of shearing edges protection of crushing edges step edge safety sensitive edge seal edge |
