Safeguard Your Tooling, Robot & Assembly System with an Overload Protection Device (OPD)
How It Works – The OPD’s mechanical wrist is held rigid pneumatically during normal operation. Varied stiffness to accommodate payload is achieved by adjusting the input air pressure. Once an overload is detected, a signal is generated to shut down, or correct your process, and the mechanical wrist transforms to a compliant state, protecting equipment and end-of-arm tooling. The OPD is easily reset by placing the mechanical wrist and interface module in their ready positions.
Two Modes of Protection – PFA’s OPD provides for independent adjustment of both pneumatic rigidity and electronic sensitivity, thus allowing you independent control of the amount of force and the amount of tooling plate travel required to initiate a protective function. As applications vary, this flexibility ensures the best possible performance under all conditions.
Modular Interface – The interface module provides all the necessary components for “plug and play” operation. Multiple signal outputs (source, sink, and NO/NC relay contacts), three point sensor adjustments, and integrated air valve, vent valve controls, ensure that all the work is done for you. Install, apply services, and you’re protected.
