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.

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.

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.
