Used EPSON G20-A04S 4-Axis SCARA Industrial Robot for Sale
The EPSON G20-A04S is a heavy-payload, long-reach 4-axis SCARA industrial robot designed for demanding industrial automation applications. As part of Epson's G20 series, it combines a rigid arm structure with high payload capacity and high-speed motion, making it suitable for applications where both handling capability and productivity are important.
With a 20kg maximum payload and 10kg rated payload, the G20-A04S is designed to handle heavier workpieces, fixtures and end-of-arm tooling than conventional small SCARA robots. Its 1000mm arm length provides a large working envelope while maintaining the advantages of a SCARA configuration.
The robot features a 420mm Z-axis stroke, providing substantial vertical travel for loading, unloading and component transfer applications. The standard G20-A04S configuration uses a tabletop mounting arrangement, while the wider G20-A0x platform is also available in ceiling- and wall-mounted configurations.
The G20-A04S provides ±0.025mm repeatability for Joints 1 and 2, ±0.010mm for the Z axis and ±0.005° for the fourth rotational axis. This combination of payload capacity and positioning accuracy makes it suitable for repetitive industrial production tasks.
With a 0.42-second standard cycle time, the G20-A04S is capable of high-speed repetitive operation even when working with heavier payloads. Epson's G20 platform uses a high-rigidity arm design and PowerDrive servo technology to maintain fast acceleration and smooth motion.
The G20 series is designed with Epson's Max-E work envelope concept, helping maximize usable workspace while reducing the footprint required for certain applications. This can be especially valuable in production lines where floor space is limited.
The G20-A04S is compatible with the EPSON RC700A controller and Epson RC+ programming environment. Depending on configuration, the G20 platform can also support vision guidance, conveyor tracking and industrial communication options.
