Open Arm
Super-compact air clamp for applications where space is at a premium. Similar to a wide-opening vertical-handle toggle clamp, except operated by an air cylinder instead of by hand. Toggle linkage provides high holding capacity and insures positive mechanical locking even if air pressure fails. Clamping arm opens 100°. Slotted open arm provides adjustable spindle location. 100 lbs. holding capacity.
This clamp is operated by a 3/4"-bore double-acting air cylinder, with Buna-N seals for -20° to +200°F operating temperature. Two #10-32 ports. 100-psi maximum input air pressure exerts 100 lbs. maximum clamping force at center of arm.

This clamp is optionally available with position-sensing capability, incorporating a special air cylinder with a magnetic piston ring. This allows monitoring cylinder position with a Hall-effect switch.
