pressure sensitive bumpers

Gamma System pressure sensitive bumpers are used to provide protection of persons against impacts with vehicles or parts of machines in motion such as AGVs, travelling lifts, wire-guided vehicles, automated warehouses, etc… A sensor, securely fixed to a supporting plate, is fitted inside the bumper. The whole assembly is then embedded in polyurethane foam and protected with a waterproof covering material. Careful construction and optimum materials used ensure maximum reliability of bumpers and quick generation of signals which are used to stop hazardous motion. Gamma System bumpers are available in standard shapes or in special shapes to customer's design. The pressure sensitive device is controlled via adequate electronic, safety devices.

OPERATION
When a slight pressure is applied to the bumper, its inner sensors come into contact thereby generating an electric signal which, in turn, stops the motion of the component. With the bumper is in the idle state, its safety contact is open. If a pressure is applied on the contact, after a pre-travel of approximately 10 - 30 cm, depending on the size, the inner contact of the sensor makes and the safety module Series GP02/S2 instantly generates a stop signal to the circuit (the NC safety contact of the module breaks). Besides the pre-travel, the bumper still allows for further compression, which is called ”overtravel” and which depends on the depth of the bumper. Overtravel permits deadening further on the possible collision against any obstacle. In the event that impact takes place, the bumper will immediately stop all hazardous motion thanks to its extremely short tripping time.
