More Reach - Slimline Design

The Epson C4L 6-axis robot is the Long Reach model within the new C4-Series product lineup. As the next logical step to our popular C3 robots, the Epson C4-Series was introduced with the new C4L model to allow for applications which require more reach while maintaining a slim design. The Epson C4L provides a slimLine design for maximum flexibility along with long reach and a 4Kg payload. The C4L includes the same unique compact wrist pitch design as with the C4 to allow easier access into tight work areas. With outstanding flexibility, Epson C4 & C4L robots were made for big jobs in tiny spaces. The new Epson C4L improves on the C4 by allowing similar payloads at 4Kg while providing 900mm of reach along with fast speeds and cycle times.

The Epson C4L cycle times are 0.47 seconds. High speed with a slimline design and good payload capability all contribute to the C4L's outstanding overall performance. Normally arms with more reach require a much larger arm design. The C4L weighs in at just 29Kg which puts it in a class all by itself. It's the lightweight workhorse for longer reach applications which require tremendous flexibility allowing the Epson C4L to do applications that other arms in the same reach class can't.

How Do We Do It?

The C4L combines the compact wrist design of the C4 along with a slimline body design to keep overall weight down while maximizing motion flexibility. Our slimline body and compact wrist design enable greater motion range and less mechanical restriction than comparably sized models. The key to our superior performance is our new QMEMS based servo technology which minimizes vibration and maximizes accelerations/decelerations and overall motion performance.

Industries We Serve

Epson C4L Long Reach 6-axis robots are ideally suited for the Lab Automation, Medical, Consumer, Food, Automotive, Electronics, PC Peripheral, Semiconductor, Plastics, Appliance and Aerospace industries. They can be used for a wide variety of applications like part load/unload, pallet and tray transfers, kitting, assembly and many more. There are thousands of different applications that these robots can handle. Give us a call and let us help you with your next application.

Building on the success form the Epson C3 Compact 6-axis robots, the Epson C4 & C4L 6-axis robots were made from the ground up for maximum flexibility, motion range and speed with an increased payload capability. They include all the latest advances in robot design and performance. Epson C4L Compact 6-Axis Robots combined with our high performance servo technology yield high performance results that customers have come to appreciate and expect from Epson. Also, included with our new C4 Compact 6-axis robots is our new leading edge motion control feedback system utilizing Epson QMEM's (Quartz Micro Electro Mechanical Systems) which sense angular velocity and feedback to our servo motion servo systems to help significantly reduce vibration during motion and stop/start which means faster cycle times and more throughput.
