The clamping principle of GN 860 pneumatic toggle clamps is identical in construction and dimensions to the manually operated GN 810 vertical acting toggle clamps.
To ensure an extended life of the mechanical parts as well as the air cylinders the operating pressure should not exceed 6 bar.
Pneumatic toggle clamps in the U-bar version with two flanged washers (Type AP3) can accommodate an application specific clamping screw. A spindle assembly with neoprene rubber tip is also included for Type CP3.
Type EP3 version can either be utilized by welding the clasp which can then accommodate an application specific hold-down fastener component, or by utilizing the bar in conjunction with the GN 809 clamp mounts to hold the workpiece in place.
These toggle clamps are also available in sizes 200 and up as a version M (magnetic piston). In conjunction with GN 896.1 / GN 896.2 proximity switches, the piston position can be sensed and the generated impulse can be used to transmit an electrical signal.
