ASPINA Electric Two-Finger Grippers

The ASPINA ARH250D-P40, ARH250D-P80, ARH205D-P40, and ARH205D-P80 are electric two-finger grippers for handling rectangular components, circuit boards, and box-shaped workpieces. All four models feature adjustable gripping parameters, replaceable fingers, and a hollow channel for cable or tube routing. ARH250D provides higher-force handling, while ARH205D offers a lower-force option for lightweight and delicate parts. The Aspina DOBOT+ plug-in supports connection setup, status retrieval, and basic gripping control on compatible DOBOT CRA and Nova series robots.

Product Highlights

Wide Opening Range
P40 models provide a maximum opening width of 73 mm, while P80 models provide 150 mm, allowing selection based on workpiece size and application requirements.
Adjustable Gripping Parameters
The grippers support adjustable gripping force, position, and operating speed. ARH250D models provide higher gripping force, while ARH205D models support lower-force handling of lightweight and delicate parts.
Hollow Channel and Replaceable Fingers
The central hollow channel accommodates cable or tube routing for optional equipment. Replaceable fingers allow workpiece-specific finger shapes, with additional components selected for the application.
DOBOT+ Integration
The Aspina DOBOT+ plug-in provides connection setup and testing, status retrieval, and basic gripping control through DobotStudio Pro for supported CRA and Nova series robots.

Application

Pick-and-Place
Transfers rectangular components, circuit boards, and box-shaped workpieces between workstations, with gripping conditions selected for the workpiece geometry, material, and weight.

Small-Box Palletizing
Handles and stacks small boxes using a model and finger configuration selected for the box dimensions, weight, and gripping conditions.

Maximum opening widths apply with standard fingers installed. Gripping force is a typical value for one finger at an opening angle of 50°. Gripping weights apply when approaching the workpiece from above and depend on finger and workpiece materials and geometry. The robot’s payload limits also apply. Body dimensions exclude moving parts. Opening/closing times refer to a full-stroke movement.
