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.

  • Ultra high performance and flexibility — high throughput with large payloads and multiple arm configurations to accomplish the most demanding high-precision, small-parts assembly needs
  • Unique high-power-density SCARA — innovative, compact design handles heavy workloads at fast speeds, all in a small footprint
  • Fast cycle times — high acceleration, smooth motion and fast settling times help maximize throughput with proprietary GYROPLUS vibration reduction system, plus no ringing or overshoot1
  • Ultimate ease of use — intuitive and feature-packed Epson RC+ development software helps create powerful solutions with a simple user interface, integrated debugger and advanced 3D simulator
  • Low total cost of ownership — includes battery-less encoders, a built-in Ethernet cable and Epson RC+ software with no recurring license fee; rich suite of safety features included with RC700E controller
  • SafeSense technology — standard and advanced safety features can allow for increased productivity and worker protection while potentially minimizing machine footprint due to the reduction of physical barriers
  • Optimized footprint — multiple mount and cable bottom exit options; 250, 300 or 350 mm reach available; unique curved arm (350 mm) option maximizes work envelope
  • Built for demanding environments — Standard, Cleanroom (ISO3)2 and ESD, and new standalone ESD models available
  • Advanced integrated options — Vision Guidance, Parts Feeding, Force Guidance, Conveyor Tracking, Fieldbus, API.NET and Arm Length Calibration
  • Industry 4.0 ready — available OPC UA for robotics provides connectivity, integration and monitoring
