535866

Parallel gripper HGPT-25-A-G2

The Festo part number 535866 is a double-acting industrial component featuring a parallel 2-finger design with a size of 25 and a stroke of 6 mm per gripper jaw. Utilizing an inclined plane and guided motion sequence with a gripper force back-up during closing, this unit operates on dried compressed air, lubricated or unlubricated, at a working pressure of 5 to 8 bar and sealing air from 0 to 0.5 bar. It achieves a maximum replacement accuracy of 0.2 mm or less, a repetition accuracy of 0.04 mm or less, a maximum operating frequency of 3 Hz, and includes position detection for a proximity sensor.
