The RSP Swivel tool changer STC20 is a unique combination of a swivel and a tool changer. As the sole supplier, we offer integrated swivel- and tool changing functions, which combine the free rotation of axis 6 with compactness and minimal extension from the robot’s tool plate. RSP‘s swivel tool changers unite the best of two technologies and together with our own developed and patented slip ring solution it provides maximized reliability.

All our tool changers feature the patented locking device, TrueConnect™. It reduces play to the minimum and enables absolute alignment repeatability throughout its lifespan. With its unique design, it does not require exact alignment before docking with different tools. Find out more about the TrueConnect™ technology.
