No need to find separate robot tool mounts and electrical connectors, these grippers come ready to attach to robot arms with standard ISO 50 mounting hole patterns. Designed to run on compressed air, they’re often used to pick and place items in packaging, machine-tending, and machining applications. Use a regulator (not included) with your compressed air to manually adjust the air pressure that will open and close these grippers for grasping and releasing items from the inside and outside. Since these grippers will open and close at the same force and stroke with every cycle, they’re good for picking items of a similar size and material. If you need to pick items of varied sizes and materials from one cycle to the next, or items that are easy to compress, programmable electric grippers would be a better choice. When selecting a gripper, be sure to match your robot arm’s manufacturer series and model number. Fingers are not included.
These grippers work with your teach pendant, which signals an integrated solenoid valve, to activate the grippers. Two magnetic sensors send information about an item’s location to your robot arm. The sensors have an LED status indicator that shows you if the gripper has picked or released the item. All of these grippers are rated IP40 to prevent objects larger than 1 mm, such as wire, from making contact with a live circuit.
Warning: Never use to lift people or items over people.

Circular grippers are best for a snug grip on round objects.
Grippers for Universal Robots (UR) arms are UR+ certified, so they've been tested and approved to work seamlessly. Plug the included software directly into your teach pendant to program the gripper.
Grippers with PNP signal output communicate proximity with a positive signal, while those with NPN signal output send a negative signal.

![]() Scale |
Attach adjustable finger mounts to your Schunk grippers, so they can handle a wider range of part sizes and shapes. Each mount has a removable positioning slide that moves along a rail, which has a scale for making adjustments. Connect your fingers to the slides, position them on the rail, and tighten the knob to secure them in place. Use one mount for as many fingers as your gripper will hold.

Build a complete robot gripping tool using these grippers, fingers, and robot tool mounts. They’re quick to assemble, so you can test and iterate rapidly to improve their productivity and reliability. Reconfiguring them for a new job won’t take long either.

Make fingers open and close with equal force in order to grasp and release parts from the inside or out. Grippers with a higher stroke width support a wider grip. Connect them to robot tool mounts using gripper configuration kits.
Air-powered grippers run on compressed air. Circular grippers hold small cylindrical parts more snugly and centered than parallel grippers. However, they can’t hold cube-shaped parts.

Signal when 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 piston of air-powered grippers or the motor of electric-powered grippers. Sensors with programmable two-position detection send a signal when fingers open and close, letting you trigger actions in your system based on both signals.
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.
PNP sensors communicate proximity with a positive signal, while NPN send a negative signal.
