GN 862.1 pneumatic toggle clamps are built from the same construction as GN 862.
The special features of these clamps are that they can be mounted in two different planes, and they can also be operated manually via the grip handle. For example, they can individually be manually closed, and then all clamps can be opened at once via the pneumatic function.
To ensure an extended life of the mechanical parts as well as the air cylinders the operating pressure should not exceed 6 bar.
GN 862.1 pneumatic toggle clamps are also available as a version M (magnetic piston). In conjunction with GN 896.2 proximity switches, the piston position can be sensed and the generated impulse can be used to transmit an electrical signal.
