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.

Lever-Locking Robot Tool Changers

Switch out end-of-arm tools with ease. These tool changers use lever-locks for fast, tool-free swaps. Lift the lever to release a tool, slide in a new one, and close the lever—the down position gives you a clear visual that it’s secure. These tool changers have multiple ISO mounting patterns, which makes them compatible with most robot tools and arms, including FANUC CRX and Universal Robots (UR).

A complete assembly consists of one mount for the end of robot arm and a mount for each of your robot tools. All components are sold separately

End-of-Robot-Arm Mounts


		Robot Tool Calibration Styli

Bolt these mounts to your robot’s wrist with the included fasteners. Confirm that the ISO pattern for the mount matches your robot.

Robot Tool Calibration Styli—Connect a calibration stylus to your robot arm mount to line up robots with a work area. They’re often used to teach coordinate systems with machine vision cameras for robot guidance. These styli also help teach points with tight tolerances—the pointed tip ensures you’re teaching the exact center of your parts.

Robot Tool Changers with Electric and Air Pass-Throughs

Quickly swap air- and electric-powered robot tools with these tool changers. Pass-throughs for air and electric connections run through the changer, so you don’t need to disconnect and reconnect air lines or cords when switching robot tools. The separate mounts for your robot arm and tool connect with a lever-locking clamp. Lift the lever to release a tool, slide in a new one, and close the lever to secure it. These tool changers have multiple ISO mounting patterns, which makes them compatible with most robot tools and arms, including FANUC CRX and Universal Robots (UR).

A complete assembly consists of one mount for the end of robot arm and a mount for each of your robot tools. All components are sold separately.

End-of-Robot-Arm Mounts


		Robot Tool Calibration Styli

These mounts pass power and signals from your robot to the connected tool. Two air inlets supply compressed air to single- and double-acting pneumatic tools. Bolt these mounts to your robot’s wrist with the included fasteners, then connect the M8 socket to the plug in your arm. Confirm that the ISO pattern for the mount matches your robot.

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.

Robot-Ready Electric Vacuum Lifters

Attach these lifters to FANUC CRX or Universal Robots collaborative robots. They handle items up to 3.5 times heavier than our lifters for lightweight items. Because they use electricity to pick up and move items with suction, there’s no need for compressed air or air control valves. They don’t have pinch points or sharp edges, so they help you meet ISO/TS 15066 international safety standards for people working near robots.

Often used in packaging, palletizing, and material handling, these lifters can grip everything from cardboard boxes to bags of screws. With soft rubber cups, they’re less likely than pick-and-place grippers to damage glass, thin plastic, and other delicate objects. To install, plug the cord into your robot arm. It carries both power and control signals.

Vacuum Lifters

These lifters include a robot tool mount, vacuum generator, quick-change cup mount, vacuum cup assembly, extra vacuum cup, and cord. Use the quick-change cup mount to swap in other vacuum cup assemblies (sold separately).

Once installed, use your robot program to turn suction on or off. An integrated vacuum switch tells your robot when an item is picked up, so it can move to the next location. View and adjust vacuum levels and other settings with an onboard screen and keypad.

Lifters for FANUC CRX arms are FANUC approved and lifters for Universal Robots (UR) arms are UR+ certified, so they’ve been tested to work seamlessly with your robot. For simple integration with your teach pendant software, download FANUC and URCap plug-ins from the manufacturer’s website.

Maximum Weight Capacity—Maximum weight capacity is achieved only when lifting items with smooth, nonporous surfaces, such as those made from glass and sheet metal. Materials like cardboard leak air when lifted, which reduces your lifter’s capacity. For instance, you can lift about 25% of the maximum capacity when using these lifters on a cardboard box similar to those we ship our parts in.

Robot-Ready Electric Vacuum Lifters for Lightweight Items

Made for FANUC CRX and Universal Robots collaborative robots, these lifters use suction to pick up and move lightweight items, up to 6 lbs. They run on electricity, so you don’t need compressed air or air valves. Often used in packaging, palletizing, and material handling, these lifters can grip everything from small cardboard boxes to bagged screws. With soft rubber cups, they’re less likely than pick-and-place grippers to damage glass, thin plastic, and other delicate materials. They’re also simple to set up—a single cord supplies both power and control to your robot arm. They help you meet ISO/TS 15066 international safety standards for people working near robots because there are no pinch points or sharp edges.

Vacuum Lifters

These lifters include a vacuum generator with a robot mount, a cord, and two types of vacuum cups. Use the flat cup for items with level surfaces and the single-bellows cup for gripping tilted items or items of different heights. You can also use your own vacuum cup if it has a compatible _1/4 BSPP threaded connection. For large items, items that might break if lifted from a single point, or material with uneven weight distribution, use 2-, 3-, or 4-cup assemblies (sold separately).

Once you’ve installed these lifters, use your robot program to turn suction on or off. An integrated vacuum switch tells your robot when an item is picked up, so it knows when to move to the next location. Adjust the vacuum level using the arrow keys on the lifter body. These lifters achieve maximum weight capacity only when handling items with smooth, nonporous surfaces, such as glass or sheet metal.

Cup Assemblies


2 Cup	3 Cup	4 Cup

Cup assemblies attach directly to the bottom of vacuum lifters. Swap out your single cup for multiple cups for more stability—they spread suction across larger areas. Use them to pick up thin glass, plastic sheets, and other items that might flex or break when lifted from a single point.
