Molex Advances Robotics with MiniMix Connectors

In a major step for the robotics sector, Molex, a key player in global electronics, has introduced the MiniMix Hybrid Power and Signal Connectors. This innovative connector is specifically crafted to elevate the mass production capabilities of humanoid robotics, autonomous mobile robots (AMRs), and sophisticated industrial automation systems. The MiniMix connector offers an advanced solution by merging 15.0A power and 1Gbps Ethernet within a remarkably compact interface, streamlining the installation process for robotic joints, actuators, and mechanisms constrained by limited space.

Overcoming Production Challenges

Manufacturers of humanoid robots are facing significant manufacturing bottlenecks as they transition from prototypes to full-scale production. Traditional methods of wiring joints have become a hindrance to efficiency. Brian Hauge, the president and Senior Vice President of Consumer and Commercial Solutions at Molex, pointed out that manual assembly is labor-intensive and prone to errors. The introduction of the MiniMix connectors aims at eliminating these inefficiencies, allowing designers the freedom to create sleek, lightweight, and responsive robotic systems that can be produced at scale.

The MiniMix connector is the industry's smallest hybrid connector, measuring just 5.65mm, and requires up to 50% less routing area than its alternatives. This small size allows it to easily pass through narrow channels within robotic limbs and joints, where traditional bulky connectors would fail.

Features and Specifications

The MiniMix connectors feature both vertical and right-angle orientations which cater to varying layout requirements, optimizing internal space while reducing cable strain. Importantly, these connectors maintain a robust and vibration-resistant mechanical design that can endure endless movement cycles and continual flexing, ensuring long-term reliability amidst the demanding operational environments of robotic systems.

With the ability to consolidate multiple functions into one integrated solution, the MiniMix connectors significantly reduce the total connector count and assembly effort, alleviating challenges that have plagued robotics engineers for years. This integrated approach not only enhances manufacturing efficiency but also reduces potential failure points that can arise from excessive manual soldering and assembly.

Tailored for Next-Generation Robotics

As the robotics technology landscape evolves, there is a growing need for connectivity solutions that prioritize space, weight, and reliability. A report from McKinsey & Company in 2026 revealed that joint actuator systems account for 40% to 60% of the total bill of materials (BOM) in humanoid robots. As robotics designers incorporate approximately 50 articulated joint actuators, integrated solutions such as the MiniMix connectors will become essential for successful implementations.

With these connectors, manufacturers can expect faster plug-and-play assembly options, minimized harness weight, and an overall increase in production output, fostering further advancements in humanoid robotics capabilities.

Availability

Molex is currently offering samples and functional evaluation assemblies of the MiniMix Hybrid Power and Signal Connectors for customer design integration and trial evaluations. Full-scale commercial production is anticipated to commence by late 2026.

Molex continues to be a leader in robotic connectivity solutions, enhancing the functionality of humanoid systems and ensuring seamless integration across complex AI-driven applications, solidifying its role in the future of robotics innovation.

As these new connectors find their way into the market, they promise to push the boundaries of what is achievable in robotics, combining power and intelligent design into the next generation of automated systems.
