Air-Powered Grippers
Combine these grippers with your gripping fingers to lift and move items in pick-and-place applications.
Angular grippers allow a more secure grip on irregularly shaped loads. Grippers with a spring jaw return have a single air port to close the jaws and grip items from the outside. An internal spring opens the jaws to release the grip. Grippers with a forced-air jaw return have two air ports: one to move the jaws open and another to move them closed. The jaws grip items from the outside as well as the inside.
Grippers with steel jaws are harder and stronger than aluminum. IP67-rated grippers are dust tight and can be submerged in up to 1 meter of water for 30 minutes.
Note: Choose a gripper with a holding force at least 10 times your item's weight.
Warning: Never use to lift people or items over people.

Add optional sensors to your gripper to signal when fingers are either open or closed (open and closed for sensors with two-position detection), and use that information to trigger other actions in your system. Since they’re magnetic, they detect the finger position using magnets placed on the piston.
Sensors with a plug connection work with the input/output on robot tool mounts with a power/signal block. Sensors with a hardwire connection have wire leads you either wire to a plug or hardwire to a power source.
NPN sensors communicate proximity with a negative signal, while PNP sensors send a positive signal.
Sensors with two-position detection send a signal when the fingers open and close, so you can trigger actions in your system based on both signals.

Finger blanks come ready to mount, so you can make custom fingers without starting from scratch. Just machine the blank’s gripping end to create fingers that will securely grip your specific parts.
When used in pairs, individual blanks have a symmetrical design that’s suitable for most applications.
Aluminum blanks are lightweight and resist rusting in wet environments. They’re softer than steel blanks, making them easier to machine and less likely to scratch your parts.
Steel blanks are stronger and more durable than aluminum blanks, so they’re less likely to break if they hit a nearby object. You can harden them for even more strength and durability.

Finger blanks come ready to mount, so you can make custom fingers without starting from scratch. Just machine the blank’s gripping end to create fingers that will securely grip your specific parts.
Uncut pair blanks can be cut off center, making them good for applications where symmetrical fingers may hit nearby objects, such as when moving around machine spindles and parts trays during machine tending.
