Transfer modules enable reliable transmission of media, data and energy between a robot and its end effectors. They form the interface that allows tool changers to support multiple processes within the same robotic cell. Stäubli transfer modules are designed for long service life, low wear and stable performance even under frequent change cycles. Available module options include pneumatics, vacuum, liquids, cooling, hydraulics, signal and power transmission, data communication, grounding, mass current and optical signals. This flexibility allows tool changers to support a wide range of applications, from simple grippers to complex multi-function tools. Transfer modules ensure clean, secure and dependable connections that keep robotic automation running efficiently in all types of production environments.
