GELBAU’S Contact-Duo-Profiles are made to secure edges at power-driven doors and gates, shutters and barriers, passenger's doors in buses, trams and trains, movable shelves, loading platforms and safety devices on machines.

Patented closing edges are used on the safety systems to secure edges against crushing and shearing at power-driven doors and gates, in public transport vehicles, at mobile rack-systems and at machinery safety devices.

The system consists essentially of two components, the Contact-Duo-Profile as the sensor and an electronic evaluation unit.

The Contact-Duo-Profile accommodates two parallel electrically conductive rubber layers, insulated against each other.

In each rubber layer are tinned copper wires extruded in an axial direction. There is a closed circuit flowing through the conductive zone, which is monitored by the evaluation unit.

By mechanical pressure on the Contact-Duo-Profile electrical contact is made, causing the safety contact at the evaluation unit to open.
