GN862.1 Pneumatically Operated Clamps, Magnetic Piston
A special feature of these pneumatically operated clamps, GN 862.1, is 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.
These toggle clamps are built from the same construction as GN862.
To ensure an extended life of the mechanical parts as well as the air cylinders the operating pressure should not exceed 6 bar.
In conjunction with proximity switch GN896.2, the piston is sensed and the generated electrical signal can be used in sequence control systems. This clamp design is used, for instance, if one workpiece is to be manually clamped with several clamps and to be released pneumatically by means of a single electrical pulse.
Two stepped side washers / clamping bolt retainers are included.
