Automatic Robot Tool Changers

No need to manually latch and unlatch end-of-arm tools, these tool changers will quickly and seamlessly swap them out for you. While manual tool changers are good for switching tools in between two different work cycles, these automatic tool changers are best for making multiple changes in a single work cycle.
A complete assembly consists of an end-of-robot-arm mount and a robot-tool mount (each sold separately) that lock together with air-powered latching cams. While you’ll only need one end-of-robot-arm mount for your robot arm, make sure you have a robot-tool mount for each of your tools. All of these mounts have standard ISO mounting hole patterns, so they’re compatible with the mounting hole patterns on most robot arms and tools. If you don't see your robot model number listed, measure the bolt circle diameter to determine mounting compatibility.
All of these mounts have air connections, so you can use compressed air to operate air-powered tools, such as grippers. They also have connections for adding electrical pass-through modules (sold separately) to power electrically controlled tools.
To create a tool docking system, use tool storage plates with tool storage bases and tool presence detectors, so tool changers can pick tools up or drop them off as they are needed.

End-of-robot-arm mounts with a coupling indicator use electrical signals to send information about the position of the latching cams to your controller, letting you know if your robot-tool mount and end-of-robot-arm mount are locked in place. It does not, however, let you know if the robot-tool mount is present.
Adapter plates let you join arms and tools with different mounting hole patterns. If you have a robot arm with ISO 40 mounting hole patterns, choose the ISO 50 mount with the adapter plate for mounting hole compatibility.

Robot-tool mounts that have ISO 50 and ISO 63 mounting hole patterns match a variety of tools without having to buy a separate adapter. Those with a tool storage plate come with a built-in plate, so tool changers can pick tools up or drop them off as they are needed.
Use blank adapter plates to machine custom mounting hole patterns.

Pass-Through Module for
End-of-Robot-Arm Mounts

Pass-Through Module
for Robot-Tool Mounts

Electrical pass-through modules pass electrical signals from your robot, through the tool changer, to your tools. You'll need one module for each tool. All have electrical connectors, wire leads, or terminals, so you can wire your own connectors. Modules with wire leads or terminals that feature strain relief do not come with a cable, but let you securely connect your own cable. Modules for FANUC (CRX) and Universal Robots are specifically wired to connect to those models.

Tool identification modules let electrical pass-through modules (sold separately) know whether or not a tool is present. You’ll need one tool identification module for each tool—program your controller to recognize up to 15 different tools. These modules don't have a connection point for passing electrical signals to the robot tool.

Tool storage plates consist of two pieces: the top piece mounts to your tool, which then rests on the bottom piece that mounts to the tool storage base. The top piece doubles as a blank plate, so you can machine custom mounting hole patterns.

Often used in complex robotic applications, tool presence detectors have a proximity sensor that sends information to your controller. Detectors for robot tool mounts require a tool storage plate (sold separately) to prevent docking a tool in an occupied plate. Detectors for end of robot arm mounts signal when a tool changer is in position for the cams to latch.
