RG6 Finger Gripper
The OnRobot RG6 is an electric two-finger gripper for collaborative robots, designed for handling heavier or larger parts than the RG2. It provides a longer stroke, higher gripping force, and software-controlled configuration without compressed air or external controllers. The RG6 is intended for applications that require higher payload capacity and wider grip range while maintaining collaborative robot compatibility.
Common uses include:
- Pick-and-place of larger or heavier components
- Machine tending and part transfer
- Assembly operations requiring higher gripping force
- Packaging and handling tasks beyond light-duty grippers
A combination of the below options are included with your purchase depending on the model selected:
- 1x robot side quick changer
- 1x tool mounting flange
- 1x cabling kit
- 1x robot kit (The robot kit is required for Ethernet IP communication and software updates for all OnRobot tooling.)
