Angular Jaw Clamps, PA series

The PA series angular jaw clamps are used in robotics and the plastics industry and more generally on all types of manipulators. They are particularly recommended for use on injection press unloading robots.

Choose a clamp with a theoretical force at least twice the effective force required.
The clamping forces in the table above are theoretical forces and are given for a pressure of 6 bar. Gripping force is inversely proportional to the distance between the gripping point and the fulcrum.

For example, for a PA 20 clamp with the gripping point 25 mm from the fulcrum, the clamping force will be:
F = 10.1 (table below) × 15/25 = 6.06 kg.

The weight of the objects to be handled is added to that of the clamp and must not exceed 1/20^th of the force exerted on the gripping point.
The opening and closing speed of the fingers can be adjusted with the compressed air regulator.

• DE: double action clamp using compressed air.
• SEF: closure by compressed air, opening by return spring (single‑acting closing).
• SEO: opening by compressed air, closure by return spring (single‑acting opening).
