Właściwości i zastosowanie:
- 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
- Pneumatically operated plunger clamps GN 890 are also available as from size 360 as version M (magnetic piston)
- In conjunction with a proximity switch( GN 896.1/ GN 896.2) the position of the piston is sensed and the generated signal can be used in sequence control systems
- Type SP3: body, steel forged
- Code M: magnetic piston from size 360 upwards (only for versin with magnetic piston)
- Elesa+Ganter toggle clamps - operating principle
