ARH350A Kit for TM


  • The ARH350A has a large finger opening diameter even in a compact size and grips small to large workpieces with one robotic gripper.
  • Adjustable torque, speed and position control achieve to grip soft hardness workpieces without any deformation.
  • Fingers of the robotic gripper are replaceable, it holds approx 3kg weight.
  • The hollow channel structure design can be used to easily install air tools, cameras, sensors and so on.
  • This product would be applied for various applications such as handling small workpieces and picking foods, medical and cosmetics industries.


  • Strong gripping force and wide opening range : A gripping force of 50N allows for lifting weights up to 3kg.
  • A wide opening diameter of 143mm enables handling of various workpieces.
  • Hollow channel structure : Tubes and cables can be passed through the hollow channel structure which makes it possible the use of additional equipment such as cameras, sensors and pneumatic tools.
  • Passive holding function : In case of a sudden electric power loss the gripper maintains its position mechanically to ensure the workpiece remains securely grasped. The support of the mechanical holding function reduces the power consumption to a minimum.
  • Precise control : Torque, position and speed control are available. Position and speed adjustments can be made in increments of 0.1%, and gripping force adjustments in increments of 0.5%. Additional functions include 2 stage operation and grip detection.
  • Customization : The fingers can be easily replaced and their shapes can be customized. Mounting surfaces allow the use of an optional finger, guide and other equipment.
