The working principle of the GN 890 pneumatic toggle clamps 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. 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 end position, such as for implementing machine controls.
