Tool changers | small payload | Epsilon E31.5

The Epsilon Tool Changer line provides a strong and reliable method for a manipulator (i.e., a robot) to quickly change between different tools/end-effectors. With Applied Robotics, Inc.’s modular design, the Epsilon offers the maximum flexibility for any application.

The line was designed to be a comprehensive family of tool changers that cover the entire range of the current CXC, MXC and Sigma tool changers we already make (ranging from 10kg. to 1,500kg.)

This is a Tool Changer Evolution. Our cam design has stood the test of time and even with extensive research; we couldn’t do anything better. In fact, we are so confident in our locking mechanism that we offer a lifetime guarantee on it. We also made sure to incorporate new market requirements and customer feedback to design these tool changers; that’s why we extended the availability of couple/uncouple sensing and came up with a direct bolt design to limit the need of adaptor plates.
