Quick-Connect Robot Tool Changers

Switch out your end-of-robot-arm tools quickly and easily with these tool changers. Separate mounts for your robot arm and tool join with a quick-connect clamp—simply open the clamp to release your tool. Often used in job shops, these tool changers make it easy to alternate between tasks. They’re also used in sanitary facilities, where tools are cleaned frequently.

A complete assembly includes an end-of-robot-arm mount, which connects to your robot wrist, and a robot-tool mount, which connects to your tool (each sold separately). Some have standard ISO mounting patterns, so they’re compatible with the mounting patterns on most arms and tools. Make sure your power source is disconnected before changing tools.

Bolt these mounts to your robot’s wrist with the included fasteners—make sure that the ISO pattern for the mount matches your robot. Mounts with multiple ISO patterns listed are more versatile and fit a variety of robot arms. If you don't see your robot model number listed, measure the bolt circle diameter to determine mounting compatibility. Mounts with only one ISO pattern listed are easy to clean and have fewer spaces where bacteria can grow.

Low-Profile Robot Tool-Changer—For applications where space is tight, use low-profile mounts. Together, the two mounts create a tool changer assembly that only adds 21 mm between your robot arm and tool. They’re also lighter than utility mounts that are the same size and material. However, they do not have pass-throughs for air, vacuum, or electrical connections.

Utility Robot Tool-Changer—Utility mounts have two pneumatic pass-throughs for air and vacuum and a power/signal pass-through for electricity. These pass-throughs let you run connections through the tool changer assembly, rather than wrapping cables and tubes around the outside. This makes it easier to switch tools, especially when changing from pneumatic to electrical tools. The 8-pin electrical connection is compatible with most robot arms and tools.

PTFE-Coated Aluminum—PTFE-coated aluminum tool changers are lightweight, so they won’t weigh down your robot arm.

304 Stainless Steel—304 stainless steel tool changers won’t corrode from frequent washdowns with harsh cleaners. They’re often used with tools that handle food.

Power/Signal Connector with 5-ft. Wire Leads—If you are mounting to an arm without an 8-pin connection, select a mount with a power/signal connector with 5-ft. wire leads. This connector has an 8-pin connection on one side and wire leads on the other, so you can adapt to any electrical connection.

Robot Tool Calibration Styli—Connect a robot tool calibration stylus to your mount to line up robots with a work area. They’re often used to direct robots to hole centers when attaching fasteners, or to help them find objects in pick-and-place applications. You can also use them to help your machine-vision camera recognize patterns and locations.

Connect these mounts to your end-of-robot-arm tool with fasteners (not included). Attach the robot-tool mount to the mount on your robot arm with the quick-connect clamp.

Bolt On—Bolt-on tool mounts have mounting holes that match the patterns on commonly used robot tools. The thread sizes also match up with the holes on t-slotted framing and fittings, so you can easily join them to tools made from framing (fasteners are not included).

Blank Mount—For a custom mounting pattern, drill your own holes into blank tool mounts.

Mounts for Two Robot Tools


	(Each component sold separately)

Equip your robot arm with two tools at once—these mounts have two angled mounting surfaces. They’re often used to speed up a robot’s work cycle, such as when two grippers swap workpieces in and out of a CNC machine. Or use them to mount tool with different functions, such as a pick-and-place gripper that puts a workpiece into a vise and a sander that finishes the workpiece. These mounts fit most robot arms, such as FANUC CRX and Universal Robots (UR). They either have mounting slots that fit multiple ISO mounting patterns or can be machined to add your own.

For a complete system, you’ll need one end-of-robot-arm mount and two tool mounts—one for each robot tool. All parts are sold separately. Mounts come with all the hardware you need to attach them to robot arms but not the hardware required to attach tools to the mounts.

Robot Tool ISO Mounting Pattern Adapters

Secure robot tools to robot arms that have different ISO mounting patterns. These adapters are compatible with most robot arm models, including FANUC CRX and Universal Robot (UR) arms. Use them to equip your robot with pick-and-place grippers, vacuum lifters, and custom tooling.

Robot Vacuum Cup Mounts

Attach threaded vacuum cups to robot arms for simple pick-and-place applications. These mounts have push-to-connect inlets on the side, so you don’t need additional fittings. Use them to connect tubing from vacuum pumps or venturi devices. Once connected, vacuum will flow directly into your vacuum cup so your arm can pick up objects. They include the hardware you need to connect them to robot arms.

Lengthen your robot arm’s reach for access to the far side of wide conveyors and the bottom of deep containers. These extensions use standard ISO mounting patterns, so they’re compatible with most robot arms and tools, such as those made by FANUC and Universal Robots (UR). They include mounting hardware to connect them to your robot arm, but you'll need to provide your own fasteners to attach your robot tools.

Automatic Robot Tool Changers

Tool changes without the downtime—your robot arm handles tool changes on its own. These tool changers allow for multiple tools to be used in a single cycle. For example, the robot can pick and place a workpiece with grippers, then automatically exchange the grippers for a vacuum lifter to pick up a different workpiece. The two mounts latch and lock together using only the motion of your robot arm—no compressed air or electricity required. These tool changers have an ISO 50 mounting hole pattern that is compatible with most collaborative robot tools and arms, including FANUC CRX and most Universal Robots (UR) models.

A complete system consists of one mount for the end of your robot arm, a mount for each of your robot tools, and a tool holder for each tool.

End-of-Robot-Arm Mounts


With Air Pass-Through	With Air and Electric Pass-Through

All mounts have air connections that let compressed air or vacuum pass through the mount, so you don’t have to run external lines that would get in the way of tool changes. They include two push-to-connect fittings to easily connect tubing. If air power is not needed, or if you prefer to use your own fittings, remove the included fittings.

With Air and Electric Pass-Through—Mounts with air and electric pass-throughs also route power, so you can switch between air-powered and electric tools in the same cycle. For example, you can use them with an electric vacuum lifter, then swap to air-powered grippers. They have a built-in 8-pole Nano M8 socket that connects directly to your robot arm.

Robot-Tool Mounts


With Air Pass-Through	With Air and Electric Pass-Through (Plug)	With Air and Electric Pass-Through (Socket)

All mounts can receive air from the mating robot arm mount and pass it through holes to air-powered tools, such as grippers. If you’re customizing a tool, make sure your design is compatible with these holes. Otherwise, use an air pass-through adapter (sold separately) to route the air from the mount to the air inlets on your tool.

With Air and Electric Pass-Through—Use mounts with air and electric pass-throughs when connecting to electric tools. Choose a mount with either an 8-pole Nano M8 plug or socket to mate with your tool’s electric cord.

Accessories for Robot Tool Changers

Air Pass-Through Adapters for Robot Tool Mounts

When using these tool changers with ready-made air-powered tools, you’ll need these pass-through adapters to get air to your tool. Adapters pass air from the robot tool mount to push-to-connect fittings, so you can add a short run of tubing (not included) to reach the air inlets that power your tool. The push-to-connect fittings are removable if you prefer a different connection.

Robot Tool Mount Holders

Image of Product. Front orientation. Tool Holders for Robot Tool Changers.

Store your robot tools when they’re not being used. These holders grip the robot tool mount on your tool. When changing tools, the robot arm drops off the current tool in an empty holder, then picks up a new one from another holder. You’ll need one holder for each of your robot tools.
