Air-Powered Grippers
Combine these grippers with your gripping fingers to lift and move items in pick-and-place applications.
Parallel grippers handle most shapes, including square, circular, and angled objects. Circular grippers are best for a snug grip on round objects.
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. 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.
