Innovative Features. Remarkable Flexibility.

Level up your automation system with the all-new C4B-Series, part of Epson's innovative 6-Axis robot lineup. Building upon four decades of expertise, the C4B-Series delivers 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.

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. Combine SafeSense technology with no-code Epson RC+® Express software to easily create industrial collaborative solutions with remarkable speed and repeatability.

Engineered to meet your unique automation needs, the C4LB offers multiple arm configurations and 600 and 900 mm reaches to accomplish the most demanding tasks with ultra high precision. Its innovative SlimLine design easily integrates into Standard and Cleanroom/ESD environments and handles payloads up to 4 kg from a conveniently small form factor. Plus, with battery-less encoders and other useful features, it supports a remarkably low total cost of ownership.

  • Ultra high performance and flexibility — high throughput with max-rated payloads and multiple arm configurations to accomplish many of the most demanding tasks with leading-edge precision
  • SlimLine design — compact wrist pitch enables access to hard-to-reach areas in confined spaces; tabletop and ceiling mounting options and 600 and 900 mm reaches available
  • 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 and Epson RC+ software with no recurring license fee; rich suite of safety features included with RC700E controller; robots are TUV-certified to meet ISO 10218-1 and UL1740 safety standards
  • SafeSense technology — standard and advanced safety features allow for increased productivity and worker protection while potentially minimizing machine footprint due to the reduction of physical barriers with a proper risk assessment
  • Industrial collaborative workcell tools — combine SafeSense technology and no-code Epson RC+ Express software to easily develop industrial collaborative solutions with remarkable speed and repeatability
