Features and Benefits


Across industries, engineers developing electronic designs face the dual challenge of achieving compact, reliable and cost-effective solutions while maintaining flexibility for future adaptations. As devices shrink and functionalities expand, maintaining secure connections in limited spaces becomes increasingly complex, especially in applications such as home appliances, medical instruments and automotive controls.

To address these universal challenges, interconnection systems that offer both versatility and reliability have become increasingly important. Such systems must provide a variety of configurations to accommodate different design requirements, including vertical and right-angle connections, various row configurations and robust features like friction locks and polarization to prevent accidental disconnections and mis-mating.

Molex’s C-Grid and C-Grid III connectors meet these needs with precision. The C-Grid system offers a comprehensive range of headers and receptacles, including breakaway, shrouded, dual-body styles and SMT options, as well as a 2-circuit shunt. C-Grid III further enhances design flexibility with modular components, allowing for a wide range of electronic packaging alternatives. These connectors not only ensure secure and reliable connections but also support ease of integration and future scalability, making them ideal for engineers looking to streamline their design processes and enhance product reliability.

Adaptability

Both C-Grid and C-Grid III connectors offer a wide range of options to meet diverse design needs. Available in multiple circuit sizes, the components come in both single- and dual-row configurations. They are designed for versatility with vertical and horizontal mounting options, easy breakaway headers and a variety of plating choices for enhanced design flexibility.
