RGI Series

Product catalog summary

Product Overview

The RGI Series Electric Rotary Gripper is a compact, dual-servo system designed for applications requiring high gripping force and infinite rotation capability. It is particularly suited for medical automation (e.g., handling reagents, blood samples, nucleic acids), electronics, and new energy industries. The gripper features simultaneous gripping and infinite rotation, solving winding issues common in non-standard designs.

Key Features

High gripping force up to 100N per jaw
Maximum torque up to 1.5 N·m (varies by model)
Infinite rotation with precise position and force control
Compact design integrating dual servo systems
Adjustable gripping force, position, speed, and rotary angle
Built-in controller with drop detection and self-locking mechanism
Multiple installation options: side, bottom, rear, and front screw holes

Applications

Designed for medical automation tasks such as opening/closing covers, scanning code detection, and large-scale nucleic acid sampling with adaptability to various tube sizes (10 mix 1 and 20 mix 1). Also applicable in electronics and new energy sectors requiring precise gripping and rotation.

Installation Guidelines

Four installation directions supported: side, bottom, rear, front
Use corresponding screw holes for secure mounting
Ensure cable bending radius of at least 40-50 mm depending on model
Secure mounting distance recommended at minimum 100 mm

Additional Notes and Recommendations

Gripping force and allowable loads depend on object shape, material, friction, and motion acceleration; consult manufacturer for specific applications.
Ensure cable bending radius is maintained (typically R40mm to R50mm) to avoid damage.
Installation must secure the gripper at least 100 mm from mounting points for stability.
Self-locking mechanism enhances safety during power loss or emergency stops.
