Product Description
The CGC-80 Series Electric Gripper is a precision three-finger centric electric gripper developed by DH-Robotics, specifically designed for accurate grasping of cylindrical workpieces. The three-finger configuration provides better centric gripping for round and spherical objects, offering more stable contact surfaces and more evenly distributed force compared to two-finger grippers.
The product features an integrated drive-control design, incorporating a high-performance servo motor, precision planetary gearbox, and rack-and-pinion transmission mechanism. It supports plug-and-play functionality and provides software plugins for major collaborative robot brands including Universal Robots, Doosan, OMRON, and TM, making programming intuitive and convenient.
The CGC-80 is available in both Two-Finger and Three-Finger configurations to suit different workpiece shapes and application scenarios:
Three-Finger Configuration: Designed for cylindrical, spherical, and easily deformable workpieces, providing highly stable centric gripping.
Two-Finger Configuration: Suitable for standard rectangular workpieces or space-constrained gripping scenarios, offering a more compact gripping solution.

FAQ
Q1: What is the difference between the two-finger and three-finger configurations? How should I choose?
The three-finger configuration uses centric three-finger gripping, better suited for cylindrical, spherical, or easily deformable workpieces, providing more even force distribution and higher centering accuracy. The two-finger configuration uses standard parallel two-finger gripping, more suitable for rectangular workpieces or space-constrained gripping scenarios. Choose based on workpiece shape and gripping stability requirements.
Q2: How does the CGC-80 communicate with collaborative robots?
The CGC-80 comes standard with Modbus RTU (RS485) and Digital I/O interfaces. Plug-and-play plugins are available for major collaborative robot brands including Universal Robots, Doosan, OMRON, and TM, requiring no complex programming for quick integration. Optional communication protocols include PROFINET, EtherCAT, and more.
Q3: Can the gripper maintain gripping force after power loss?
Yes. The CGC-80 features power-off self-locking – upon power loss, the gripper automatically locks the gripping force to prevent the workpiece from falling, ensuring operational safety.
Q4: What is the recommended load capacity?
The maximum recommended load is 1.5 kg. For heavier workpieces, please consult us for alternative models or customized solutions.
Q5: What communication protocols are supported?
Standard: Modbus RTU (RS485) and Digital I/O. Optional: TCP/IP, USB2.0, CAN2.0A, PROFINET, and EtherCAT.
Q6: Is the gripper suitable for harsh environments?
Yes. With an IP67 protection rating, the CGC-80 is dustproof and waterproof, making it suitable for demanding industrial environments and clean-room applications.
Q7: What is the operating temperature range?
Recommended operating environment is 0°C to 40°C, with relative humidity below 85%.
Q8: What certifications does the product hold?
The CGC-80 is certified with CE, FCC, and RoHS.
Q9: Can the fingertips be replaced?
Yes. The fingertips are replaceable to accommodate different workpiece shapes and sizes.
