GN860 Pneumatically Operated Clamp, Magnetic Piston
The clamping principle of these clamps, GN 860, is identical in construction and dimensions to the manually operated vertical clamps GN810.
To ensure an extended life of the mechanical parts as well as the air cylinders the operating pressure should not exceed 6 bar. In addition a lubro control unit should be fitted in the air line.
This version, M, has a magnetic piston. In conjunction with proximity switches GN896.1 / GN896.2 the piston position can be sensed and the generated impulse can be used to transmit an electrical signal.
Compatible with GN708.1 clamping bolt, with rubber tip.
