Add optional sensors to these grippers 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. 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 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 sensors 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.

Attach adjustable finger mounts to your Schunk grippers, so they can handle a wider range of part sizes and shapes. Each mount has a 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.
