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.

Electric-Powered Grippers
Unlike air-powered grippers, which leak air, these electric grippers won’t release dirt or particulates, making them good for pick-and-place assembly, packaging, and finishing jobs in labs, electronics plants, and other clean environments. All have a servomotor that opens and closes the grippers with equal force to grasp and release items from the inside or outside. A discrete I/O signal actuates the grippers with a set gripping force—use a screwdriver to select the force you’ll need. Since these grippers open and close at the same force and stroke with every cycle, they’re good for picking items of a similar size and material.
To determine if gripper fingers are open or closed, and use that information to trigger other actions, add a sensor. All of these grippers are compatible with PNP and NPN signal outputs, which means they can communicate proximity with a positive or negative signal.
Warning: Never use to lift people or items over people.
IP30 grippers prevent objects greater than 2.5 mm, such as a screwdriver, from making contact with live circuits. Suitable for use in clean rooms, they are also rated to ISO Class 5. They have one M8 4-pin connection, which brings power to the gripper and two digital input signals to the grippers' controller. All are compatible with optional inductive sensors.

Optional sensors signal when gripper fingers are either open or closed, and use that information to trigger other actions in your system. Magnetic sensors detect finger position by responding to magnets placed on the motor of electric-powered grippers. Use them with IP40 and IP64 grippers. Those with programmable two-position detection send a signal when fingers open and close, letting you trigger actions in your system based on both signals. Inductive sensors respond to a metallic flag on the gripper. They are not, however, the best choice for machining applications since metallic debris can accidentally trigger them. Use these sensors with IP30 grippers.
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 to a power source.
PNP sensors communicate proximity with a positive signal, while NPN send a negative signal.
