5 Product overview
5.1 Function
When the supply ports are pressurized, a piston rod moves out and in. The intern-
al piston rod is connected to the tip of the inverting cap. When the piston rod is
retracted, the inverting cap is turned inside out. This forms an indentation of the
surface of the inverting cap in which an object is enclosed and gripped.

6.1 Assembly of product
Fig. 2 Mounting DHEF
The DHEF fits into a mounting interface in accordance with
ISO9409-1-50-4-M6:2004-03.
1.
Use the centring collar ( 31.5mm) for centring.1Æ
2. Mount adaptive shape gripper with 4 screws (M6).
6.2 Mounting accessories
If required:
Use one-way flow control valves directly in the supply ports.
Ä
They can be used to adjust the retraction and extension speed.
To query the piston position:
Use proximity sensors in the slot www.festo.com/catalogue.7è

8 Commissioning
Requirements
Objects must always be approached centrically only with the adaptive shape
gripper to eliminate the possibility of transverse loads on the piston rod.
The inverting cap must be continuously pressurised with low pressure
è 7 Pneumatic installation.
For use in the human-robot collaboration area: use face connections.
Do not use pointed objects with sharp edges. They may damage the inverting
cap and affect its function.
Maintain permissible velocities (with/without gripped object) and note the
