Epson RS4 SCARA Robots

550mm

  • Industry Leading Work Envelope Usage
  • No Lost Space in Center of Work Envelope
  • Extremely high speed with superior cycle throughput
  • Zero Footprint Robot
  • ISO Clean & ESD Compliant Models

Epson RS4 SCARA robots are a part of the RS-Series family of robots that use a unique new design to improve both work envelope usage and cycle throughput. The arm structure was designed so that joint 2 can maneuver under joint 1 and thus utilize the entire workspace underneath the arm. Unlike other SCARA robot designs, there is no lost space in the center of the work envelope. No other robot vendor offers a 550mm SCARA robot arm which can work with pallets as large as 777mm x 777mm. A pallet size this large would normally require a SCARA arm which is almost double the size. Epson RS4 SCARA+ arms are capable of handing pallet sizes up to 600x800mm.  The RS-Series SCARA arms are also designed for speed. With super fast cycle times the RS4 is ideal for applications running in demanding industries such as Automotive, Medical, Semi Conductor, Food, Pharmaceutical, Consumer, and many others, Epson RS3 SCARA's are the unique alternative to "just another SCARA" arm and they deliver the high performance required for todays demanding applications.

RS4 SCARA+ arms are available in 550mm arm lengths with either a 130mm Z-Axis length (100mm clean). They are also available in ISO3 Clean/ESD configurations as required for the semi-conductor and medical industries.

With the industry leading ease of use of the EPSON RC+ Development Environment and a ton of integrated options, Epson RS3 Robots with Epson Controllers significantly reduce overall learning curves and development time. RS4 SCARA+ robots are available with either our compact powerful RC180 Controller or our open architecture PC based RC620+ Workcell Controller. The choice is yours depending upon your application. Both controllers feature a host of integrated options such as Vision Guide, .NET support, DeviceNet, Profibus and Ethernet/IP (RC620+ only) communications interfaces and much more. 
 

Epson RS4 SCARA+ Robots

Features & Benefits

Epson RS4 robots were created to provide high performance robots with maximum work envelope efficiency. No other SCARA in the world has the work envelope capacity ratio offered with the RS-Series models. The RS4 is a 550mm SCARA+ arm capable to working on 777mm x 777mm pallets which would normally require a SCARA arm well over 1000mm in size. Also, with movement through the center of the work envelope, the RS-Series arms can significantly reduce cycle times by traveling through shorter distances vs having to always go around the center of the work envelope. Add all this to our Industry Leading Ease of Use and Powerful Controllers and it's easy to see why Epson RS-Series robots are quickly becoming the robot of choice.
