Selecting a Connector for Industrial Robot Joints

For the demanding environment of industrial robot joints, the push-pull Series B connector is a recommended choice. This connector is engineered to handle the specific mechanical, electrical, and environmental challenges found in robotic applications.

Key Selection Criteria for Robot Joint Connectors

When choosing a connector for this application, engineers should evaluate the following core decision points:

• Mechanical Durability: The connector must withstand continuous movement and torsion. The Series B offers ±90° torsion resistance, which is suitable for the 360° rotation requirements of robot joints.
• Mating Force: A low insertion force simplifies assembly and maintenance. The Series B features a plugging force of less than 15N.
• Signal and Power Integrity: The connector must reliably transmit both power and data. It supports power transmission up to 5A and encoder signals at 100Mbps.
• Pin Configuration: The connector should offer flexibility for various joint configurations. The Series B is available with 4 to 12 pins.
• Environmental Protection: Resistance to dust and oil is critical in a workshop environment. The Series B has an IP67 protection rating.

Electrical and Performance Specifications

The electrical characteristics of the connector directly impact the robot's performance and accuracy. The Series B maintains a contact resistance of less than 5mΩ, which is essential for ensuring the robot's repeat positioning accuracy of ±0.005mm. This low resistance helps minimize signal loss and heat generation, contributing to stable and precise operation.

Application Fit and Boundaries

This connector is well-suited for multi-joint robot configurations that require a combination of power and signal transmission in a compact space. While it is designed for high torsion and environmental resistance, the suitability for a specific robot model should be verified against the robot's exact cable routing, joint space constraints, and required mating cycles. For other robotic applications, such as end-effectors or charging ports, different connector series may be more appropriate.
