Pneumatic Push Toggle Clamps GN 890

More Information to Toggle Clamps (Pneumatic) Operating instruction GN 890

Product description

The working principle of the pneumatic toggle clamps GN 890 is identical in construction and dimensions to the manual toggle clamps GN 842.

To ensure an extended life of the mechanical parts as well as the air cylinders, the operating pressure should not exceed 6 bar and a compressed air maintenance unit should be installed upstream. In addition a lubrication control unit should be mounted in the air in-feed line. The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protruding over the frame.

Toggle clamps GN 890 have a permanent magnet integrated into the piston. In conjunction with sensors GN 3380 , it is possible to detect the piston position, which can deliver a signal, for instance to a machine controller.
