8 Top Trends in Connector Technology

Although connectors may not be the most glamorous of components, they are among the unsung heroes of modern electronics, playing an important role in devices’ performance, reliability and functionality. We are seeing a surge of innovation in the development of connectors, driven by the increasing demand for miniaturization, high-speed data transmission and high reliability. 

This article examines eight top connector trends and showcases some of the outstanding products in the field. Designers who stay abreast of these trends are rewarded with new tools that can help optimize cutting-edge designs.

1. Miniaturization and High Density

As devices continue to become more compact in size and rich in features, there is a growing demand for smaller connectors that can handle higher pin densities without compromising performance. Miniaturization is enabling the design of sleeker and more portable devices, while high-density connectors are supporting more complex circuitry within limited spaces.

Example: Molex’s Micro-Lock Plus Wire-to-Board Connectors are a prime example of meeting the needs of compact device design. These connectors offer a secure locking mechanism, high current-carrying capacity and a low-profile design, making them a good fit for applications in mobile devices, wearables and other space-constrained environments. 

2. High-Speed Data Transmission

The increasing use of high-speed communication protocols calls for connectors that support faster data rates while minimizing signal loss. Such high-speed data connectors are regularly used in computing, networking and multimedia applications.

Example: TE Connectivity’s Sliver Connectors are designed to provide a robust and cost-effective solution for high-speed data transmission. Their innovative design reduces insertion loss and crosstalk, ensuring reliable performance in data-intensive environments such as data centers and high-performance computing systems.

3. Flexible and Stretchable Connectors

Flexible connectors and stretchable connectors are designed to bend, twist and stretch without losing their functionality, making them a game-changer for applications in healthcare, wearables and flexible electronics. Innovative materials development and advanced manufacturing techniques are creating new possibilities for more adaptable, user-friendly devices with enhanced performance and functionality. For more details, check out our deep dive into flexible and stretchable connectors.

Example: Nano Dimension’s DragonFly AME system makes conductive ink-based stretchable connectors possible with the precise 3D printing of multilayer flexible circuits. This additively manufactured electronics (AME) system can deposit both conductive and dielectric materials onto flexible substrates to create complex, stretchable components. Connectors built with this technology can be used in smart clothing, medical sensors and other devices where traditional rigid connectors are impractical.

4. Wireless and Contactless Connectivity

The integration of wireless and near-field communication (NFC) technologies into connectors is reducing the need for physical electric contacts, and thereby enabling new applications in medical devices and consumer electronics. 

Example: Molex’s NFC Antenna Wireless Charging Solutions are a great example of innovative wireless connectivity,  incorporating NFC technology to facilitate wireless power transfer and data communication.

5. Smart and Intelligent Connectors

Incorporating smart features – such as built-in diagnostics, monitoring capabilities and data analytics – into connectors enhances performance and enables applications like predictive maintenance, machinery identification, energy measurement and surge protection. Smart connectors can provide real-time information about connection status, environmental conditions and potential problems, which is pretty cool and adds value to many applications.

Example: HARTING's Han-Smart® Connectors are an example of intelligent connectivity designed for today’s industrial landscape. These connectors can receive, process and forward data to other systems, enabling real-time diagnostics, condition monitoring and other applications

6. Power and Signal Integration

Combining power and data transmission in a single connector simplifies design and reduces the number of components required. This approach is most valuable in compact and lightweight device designs where space is at a premium.

Example: HIROSE ELECTRIC’S ix Industrial Connectors integrate power and signal contacts within a compact form factor. Designed for industrial and IoT applications, these connectors streamline system design and reduce the complexity of cabling, enhancing efficiency and performance.

7. Robustness and Reliability

Connectors used in industrial and automotive applications must withstand harsh environments, including extreme temperatures, vibrations and exposure to moisture. Enhanced connector robustness and reliability ensure long-term performance and reduce the risk of failure in critical systems.

Example: Amphenol's Ruggedized Connectors are designed to perform reliably in the most demanding environments. These connectors feature enhanced sealing, robust materials and secure locking mechanisms to protect against environmental hazards. Used in automotive, military and industrial applications, Amphenol's ruggedized connectors ensure dependable performance under harsh conditions.

8. Modular and Configurable Designs

Modular connectors offer customization and flexibility. They are valuable in industrial automation and data center environments because they simplify maintenance and upgrades by enabling easy configuration and reconfiguration of connection interfaces.

Example: HARTING’s Han-Modular® Industrial Connectors provide a versatile solution for complex wiring requirements. These connectors allow users to combine different modules for power, signal and data transmission within a single housing. This modularity makes adapting to changing requirements in demanding environments easier. 

Looking Ahead

Designers and engineers striving to enhance device performance and functionality must stay abreast of emerging connector trends. From miniaturization and high-speed data transmission to smart technologies and stretchable materials, innovations in connector technology are enabling advancements in many applications. From the sensors in wearables to the high-speed data lines in our supercomputers, connectors are the hidden heroes of our digital lives.
