Function

–Alternating pressurisation of the supply ports moves a piston in the gripper.

This results in a double-acting function.

–A gripper with integrated spring return is used to exert the gripper force. When

exhausting the single-acting gripper: the spring return moves the gripper jaws

to the initial position.

–N/O contact: NO normally open

–

N/C contact: NC normally closed

–The piston movement is transmitted mechanically to the gripper jaws. Gripper

fingers are attached to the gripper jaws. Closing or opening the gripper fingers

clamps the payload by the outer contour or the inner contour.

–

The gripping force is adjusted by external regulation of the operating pressure.

–The gripper has integrated fixed flow restrictors. If the maximum gripper finger

weights and the maximum gripper finger lengths are in compliance, external

flow control is not required.

6.3 Mounting gripper

If necessary, mount the proximity switches before mounting the gripper.

When using proximity switches for sensing the end position, take the following

into account:

• Interference from ferritic attachments, e.g. retaining screws made of ferritic

steel.

• Projecting proximity switches, if applicable.

• Cable outlet direction of the proximity switches.

• Sufficient space for the connection components.

• When sensing from both end positions: use separate slots for the proximity

switches.

NOTICE

Loss of function due to contamination in the connections.

• Keep ports and tubing lines free from dirt particles and foreign matter.

The use of a check valve prevents the payload from dropping in the event of

a sudden pressure drop. The use of a one-way flow control valve also permits

adjustment of the opening and closing times.
