EC Series SCARA Robots The EC251S/EC251C and EC351S/EC351C define a whole new class of SCARA robots. While improving on the repeatability and speed for which EPSON Robots are known, we also reduced the size with the EC series robots to provide a small footprint solution for many applications that don't require larger robots. This translates to a cost/space savings while maintaining high performance. EC Series robots are ideal for applications such as fiber optics component assembly, hard disk assembly, semiconductor die handling and other automation jobs where parts are small and space is at a premium.

EC251S/EC251CSpecifications

The EC251S Robot is a four axis unit with AC servo motors for reduced maintenance and harmonic drives for increased speed and reliability. The EC251S has a horizontal reach of 250mm (hence the name EC251S) and a Z Axis vertical stroke of 120mm. The EC251S robot also has a standard (1" x 12" x 1" and back) cycle time of 0.43 seconds and a repeatability of 0.010mm (0.0004 in.)! With numbers like these, the EC251S robot is one of the fastest most repeatable SCARA robots available with a better price/performance/space ratio of any competitive unit.

EC351S/EC351C Specifications

Like the EC251S Robts, the EC351S Robot is a four axis unit with AC servo motors for reduced maintenance and harmonic drives for increased speed and reliability. The EC351S has a horizontal reach of 350mm and a Z Axis vertical stroke of 120mm. The EC351S robots have a standard (1" x 12" x 1" and back) cycle time of 0.43 seconds and a repeatability of 0.015mm (0.0006 in.)! With numbers like these, the EC351S robot is also one of the fastest most repeatable SCARA robots available with a better price/performance/space ratio of any competitive units.

Powerful Controls

With our EPSON RC+ PC based Workcell Controller EPSON has redefined the term easy to use. Many of our customers have experienced significant reductions in development time due to the ease with which our robots can be programmed. With integrated options such as Vision Guide for robot guidance and inspection applications, VB Guide Active X controls, Ethernet I/O, Force Sensing and others, EPSON RC+ is not only easy to use but also flexible in the different applications it helps to solve.

Z-Axis Stroke and Features

The Z-Axis for the Mongoose EC Series Robots comes standard with 120mm of stroke. This axis includes a brake that engages to hold tooling and payloads in place when servo motor power is removed. A brake release button is easily accessible on top of the axis for quick release and the quill is hollow which allows easy channeling of electrical and pneumatic lines.

Fast Tool Rotation

Cycle time is the name of the game and just moving quickly in the XY plane isn't enough. This is why U Axis (or the tool rotational axis) speed is so important for most applications. The Mongoose EC Series U Axis travels a full + 360 degrees and with a top speed of 2368 deg/second is nearly twice as fast as most competition which translates to more parts processed per hour.

Absolute Encoders

All EC Series robots come standard with Absolute Encoders. This means that they don't have to be sent to a home position when first powering the controller up. This can save valuable time during startup each day. Just power the EPSON RC+ controller on, and the EC Series Robots are ready to begin their work for the day.

Class 10 Clean Room Capable

The EC251C and EC351C Robots are Class 10 Clean Room versions of the standard EC251S and EC351S. The only performance difference is that the Z-Axis stroke is 100mm on the EC Series Clean Robots vs. 120mm on the standard EC Series Robots. The EC251C and EC352C are also available at remarkably affordable prices.
