The U1-050 universal compliance compensator combines a variety of features to achieve adaptability in tasks such as automated assembly and robotic finishing. It complies in many directions to overcome misalignment between the tool and the workpiece. The patented mechanism is suitable for high-endurance applications and offers simultaneous X-Y lateral compliance, X-Y-Z axis rotation and Z compression. The pressurized internal reset piston returns the device to a repeatable center. Stiffness can be tuned for specific payloads by varying the pneumatic pressure. The compensator can be configured for either a PNP or NPN compliance sensor and has an option for environmental protection.
