Properties and application:
- Pneumatically operated clamps GN 861 have been constructed in such a way as to make them easily demountable
- The bearing pins are axially fixed with circlips
- This allows the clamping arm to be modified to suit any particular application
- To ensure an extended life of the mechanical parts as well as the air cylinder the operating pressure should not exceed 6 bar
- In addition a lubro control unit should be fitted in the air line
- Pneumatically operated clamps GN 861 are also available as version M (magnetic piston). In conjunction with a proximity switch GN 896.3 the piston position is sensed and the generated signal can be used in sequence control systems
- Type EP: solid clamping arm
- Coding M: Magnetic piston
- Elesa+Ganter toggle clamps - operating principle
