Epson GX4-Series. Taking SCARA robot performance to the next level.

Introducing the GX4-Series, part of Epson’s new high-power-density SCARA robot lineup. The GX4-Series builds upon four decades of expertise to deliver next-level performance and flexibility in a compact footprint. A breakthrough in productivity, this series uses advanced GYROPLUS® vibration reduction technology to provide fast production speeds and smooth motion control, all with high payloads.

Featuring SafeSense technology with an EN/ISO 13849 safety rating, the RC700E controller provides safety rated speed and position monitoring that, with proper risk assessment, can allow humans and robots to interact without a safety fence. This next-level functional safety technology helps improve productivity by enabling faster interaction with machines for daily operations and maintenance. And by potentially removing the need for physical safety barriers, users can help reduce the footprint and overall cost of their robot automation system.

Engineered to meet your unique automation needs, the GX4B offers multiple arm configurations and a 250, 300 or 350 mm reach to accomplish the most demanding tasks—including assembly, pick and place, and other intricate small-parts handling—with ultra high precision. Its innovative, compact design easily integrates into Cleanroom and ESD environments and handles payloads up to 4 kg from a conveniently small form factor. Designed for ease of use, Epson RC+® software works seamlessly with the GX4B to create powerful automation solutions and offers integrated options to simplify the most complex applications. Plus, with battery-less encoders, a built-in Ethernet cable and other useful features, it supports a remarkably low total cost of ownership.
