Construction of the HSB Bumper

The bumper is built up of a soft polyurethane foam, in the interior of which contact chains are disposed immediately adjacent to the actuating faces. The number and the positions of the contact chains depend on the size and the intended application of the bumper. For rail-bound vehicles or rectilinear machine movements normally only the front side of the bumper serves as the actuating face.
The bumper sensor is are built up of mechanically opening N/C contacts connected in series, in the form of a contact chain.

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.
