Festo
1187956
Swivel/gripper unit HGDS-PP-12-P1-A-B
The Festo part number 1187956 is a structural design combining a quarter-turn actuator with a parallel gripper and gripper actuator featuring two parallel gripper jaws, a 2.5 mm stroke per jaw, and a double-acting mode of operation. This component provides an adjustment range of swivel angle from 0 degrees to 210 degrees, a 210-degree swivel angle, elastic cushioning rings or pads at both ends with a fixed stop, an adjustable cushioning range of 2 mm, and a quarter-turn actuator fine tuning of -6 degrees. Operating at a pressure range of 3 bar to 8 bar in any mounting position, the unit achieves a pneumatic gripper repetition accuracy of 0.01 mm, a swivel angle repetition accuracy of 0.02 deg, a maximum gripper jaw angular play of 0.1 deg in ax and ay, and a maximum gripper jaw backlash Sz of 0.02 mm, with position sensing via proximity switch on both the pneumatic gripper and quarter-turn actuator.
