SurLok Plus™ Expansion – 2024

Amphenol Expands SurLok Plus™ Series, Enhancing Capabilities in High-Current Applications

Amphenol Industrial Operations has expanded its SurLok Plus™ Series, a move poised to significantly impact the high-current connector market. The introduction of new sizes and configurations aims to meet the growing demands of industries such as energy storage, electric vehicles, and heavy equipment, where reliability and performance are paramount.

Key Additions to the SurLok Plus™ Series

The expansion of the SurLok Plus™ lineup includes three key connectors, each designed with specific high-demand applications in mind:

1. The 10.3mm Inline Plug 2.0 Generation

This new connector is specifically tailored for the 1500V DC market, addressing the needs of industries that require robust power solutions, such as battery and control boxes in electric and hybrid vehicles. Capable of handling 360A, the 10.3mm Inline Plug integrates a quick-connect and locking system, providing a reliable alternative to traditional compression lugs. This system allows for increased power handling without the need for additional space, a crucial factor in compact and high-performance environments.

2. The 5.7mm and 8.0mm 2.5 Generation

Amphenol has also introduced non-EMI right-angle connectors in 5.7mm and 8.0mm sizes, targeting the energy storage market. The 5.7mm connector is rated for 120A, while the 8.0mm version supports up to 200A. These connectors come equipped with features like anti-mis-insertion, water protection, and 360° rotation after mating, ensuring secure and efficient connections even in the harshest conditions. These innovations are particularly relevant as the energy storage sector continues to demand higher power outputs with reliable, durable connections.

3. The 14.0mm EMI Connector

The 14.0mm EMI right-angle connector is another significant addition to the series, offering enhanced electromagnetic interference (EMI) shielding and a High Voltage Interlock Loop (HVIL) option. Designed for 1500V DC applications, this connector is well-suited for energy storage, electric vehicle, and industrial markets. The connector’s field-installable design provides an environmentally friendly alternative to traditional compression lugs, offering reliable performance in both DC/DC and AC/DC power transfers.

Impact on the Industry

The expansion of the SurLok Plus™ Series by Amphenol comes at a critical time for industries undergoing rapid electrification. The heavy equipment, energy storage, and electric vehicle sectors are all experiencing increased demand for high-current connectors that can offer both reliability and compact design. With these new additions, Amphenol is well-positioned to address these needs, offering products that combine advanced technology with practical design features.

Advanced Technology Meets Practical Design

The new connectors in the SurLok Plus™ Series feature Amphenol’s latest R4 RADSOK® technology, which increases amperage capacity while reducing insertion force, temperature rise, and voltage drop. These technological advancements not only enhance performance but also contribute to longer product lifespans and lower maintenance costs, which are critical considerations in high-stakes industrial applications.

The connectors are also designed for ease of use. The quick lock and press-to-release mechanism simplify the process of mating and unmating, even in challenging environments where speed and efficiency are crucial. Additionally, the connectors’ robust construction, including an IP67 rating and compliance with UL4128/TUV 2PfG2740 standards, ensures they can withstand harsh environmental conditions, further enhancing their reliability and durability.

Looking Ahead

As industries continue to push the boundaries of what’s possible in high-current applications, the need for advanced, reliable connectors will only grow. Amphenol’s latest additions to the SurLok Plus™ Series not only meet current industry demands but also set the stage for future innovations. By expanding the capabilities of the SurLok Plus™ Series, Amphenol is reinforcing its position as a leader in the connector market, offering solutions that are as forward-thinking as they are practical.

These developments underscore Amphenol’s ongoing commitment to innovation, providing the tools and technology necessary to drive the next generation of industrial advancements. As the market evolves, the SurLok Plus™ Series is poised to play a pivotal role in powering the future of high-current applications across various sectors.
