The verdict

The specs separate them here: the Staubli TS40 carries more, 8 kg to the Epson SCARA T6's 6 kg, and the Epson SCARA T6 reaches farther, 600 mm to 400 mm. If precision drives the job, the Staubli TS40 holds the tighter repeatability at ±0.01 mm. They run different controllers, the Epson SCARA T6 on the Built-in and the Staubli TS40 on the CS8C, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the Epson SCARA T6 lists Tabletop, and the Staubli TS40 lists Floor and Wall. Both are aimed at assembly and packaging, with the Epson SCARA T6 stretching to machine tending.

Choose this one when

Job fit first, then the controller and cell constraints that decide which arm you can actually install.

Choose the Epson SCARA T6 when

  • Competitive cost for a full-size SCARA
  • Fast planar cycle times
  • Straightforward setup with Epson RC+ software
  • Multiple reach variants available

Watch for

  • Planar kinematics limit orientation flexibility
  • Smaller support network than the largest robot brands

Choose the Staubli TS40 when

  • Sealed construction suits clean production lines
  • Fast planar cycle times
  • Tight repeatability for small-parts assembly
  • Cleanroom-rated option available

Watch for

  • Planar motion limits orientation flexibility
  • Smaller reach than larger SCARA competitors

Controller ecosystem

Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.

These arms run different controllers (Built-in vs CS8C). If your team already programs one of them, retraining programmers and stocking a second set of spares usually costs more than a small payload or reach advantage on paper.

Mounting, footprint, and mass

How the arm can be oriented in the cell, and how much mass you have to mount.

Heavier arms want stiffer bases and more clearance around the swept volume, and they push freight and rigging costs up on the install. IP ratings only cover the section they name, so a wrist-only rating protects the wrist and nothing else; check the body rating separately before you commit the arm to a washdown or dusty cell.

Application fit

Where each arm is aimed, based on the applications listed on its robot page.

Speed and cycle-time planning

Speed is rarely a single datasheet number across brands. Use payload, reach, and class as the planning frame, then confirm cycle time in a path study.

The Epson SCARA T6 is a SCARA arm rated 6 kg at 600 mm with ±0.04 mm repeatability. The Staubli TS40 is a SCARA arm rated 8 kg at 400 mm with ±0.01 mm. Class changes how speed shows up in a cell: collaborative arms slow down near people and can speed up in a guarded mode, while industrial arms run at rated speed inside a fence or scanner field. Which arm cycles faster on your part depends on the path, the payload, and the safeguarding, so confirm the takt with a path study before you quote it.

Common questions

Which has more payload, the Epson SCARA T6 or the Staubli TS40?
The Staubli TS40 has more payload at 8 kg versus 6 kg.
Which reaches farther?
The Epson SCARA T6 has more reach at 600 mm versus 400 mm.
Which is more precise?
The Staubli TS40 holds tighter repeatability at ±0.01 mm.
Should I choose the Epson SCARA T6 or the Staubli TS40?
Match the pick to the job. The Epson SCARA T6 is a SCARA arm at 6 kg and 600 mm. The Staubli TS40 is a SCARA arm at 8 kg and 400 mm.
Do the Epson SCARA T6 and Staubli TS40 use the same controller?
No. The Epson SCARA T6 uses Built-in and the Staubli TS40 uses CS8C.
How do the IP ratings compare?
The Epson SCARA T6 is rated IP20. The Staubli TS40 is rated IP54. Check wrist versus body coverage before washdown or dusty cells.
