The piston is moved up and down by compressed air.
The angled active surfaces of the wedge-hook produce a synchronized, parallel jaw motion.

Sectional diagram of gripping force maintenance version AS
Dustproof version SD
The "dustproof" option increases the degree of protection against penetrating substances.
This can either be ordered in a ready-mounted gripper version or else retrofitted to the gripper using the "SAD PGN-plus-P" retrofit kit.
Gripping force maintenance version AS/IS
The mechanical gripping force maintenance device ensures that a minimum clamping force will be applied even if there is a drop in pressure. In the AS version this acts as a closing force, and in the IS version as an opening force. The image shows the AS version. The gripping force maintenance can also be used to increase the gripping force or for one-way gripping.

Gripping force maintenance
Settings of the control cams during monitoring with inductive proximity switches
Monitoring with inductive proximity switch can be performed as standard from size 64. In delivery state, the positions "gripper open" and "gripper closed" are preset with the control cams. The inductive sensors must be ordered separately and are slid into the housing up to the stop and clamped.
In order to monitor any other position, such as "workpiece gripped" for example, both control cams can be individually set in the respective base jaws.

Optional mounting possibility under the cover sheet for customer-specific additional structure
In delivery state, a cover sheet is mounted to the gripper. This can be removed if necessary. Under the cover sheet are threads and fittings for mounting customer-specific designs for implementing additional functions.
