Features and applications
GN 890 version M (with magnetic piston) together with proximity switches GN 896.1 and GN 896.2 can be sensed and the
generated impulse can be used in sequence control systems. For further details see GN 896.1 and GN 896.2.
The working principle of the pneumatically operated plunger clamp GN 890 is identical in construction and dimensions to the
manual plunger clamp GN 842.
To ensure an extended life of the mechanical parts as well as air cylinder the operating pressure should not exceed 6 bar. In
addition a lubro control unit should be fitted in the air line.
The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protrude over the frame.
