    Max Payload : 2-3 KG

    Max Reach    : 450 – 550 mm

    1. Downsizing the equipment

    • Installation of the inverted mount provides space saving for equipment layout.

    2. High speed operation with the shortest path

    • Thanks to its slim arm, high speed operation is possible. Also inverted mounting allows the robot to travel the shortest path.

    3. Smart cable routing

    • A large, 36 mm-diameter hole in the tip of the wrist.
    • With all wires and tubes built into the machine body, the risk of interference is reduced and reliability is improved.

    4. Complicated operations can be performed (6-axis model:to be released in this summer)

    • More complicated operations such as insertion from an angle, change of orientation in an assembly process and grinding/finishing are possible.

    *1 The Allowable moment of inertia of a wrist changes with the load conditions of a wrist.
    *2 This value conforms to “JIS B 8432”.
    *3 Permitted height is not higher than 1,000m above sea level. If used in a higher place, permitted temperature is affected.
    *4 Fluids that cause the deterioration of sealants, such as gasoline-based cutting fluids, chlorine, alkali, acids, and organic solvents, cannot be used.
    *5 The maximum velocity in the chart is a maximum value. The maximum value may change depending on work programs and load conditions of the wrist.
    *6 A-weighted equivalent sound level measured according to JIS Z 8737-1 (ISO 11201). (while operating at maximum speed with rated load)
