Environmental specifications

• ESD (anti-static) specifications: GX4-A**1E*
  ESD specifications are specifications that use conductive materials for or apply plating to the major resin parts as anti-static measures.
  We have confirmed that the Manipulator tip (tool mounting section) is at ±5 V or less, even directly after the measuring operation according to Seiko Epson standards.
  If you need any other detailed information, please contact the supplier.
  Also, please check the amount of charge on any hand, wiring, or the like that you will attach to the robot on your own before use.

• Cleanroom & ESD (anti-static) specifications: GX4-A**1C*
  Manipulators with cleanroom & ESD (anti-static) specifications have a base design with the standard specifications, but as an additional feature, have reduced dust emissions from the Manipulator to enable use in cleanroom environments.

For details on the specifications, refer to the following section.
