Industry-Leading Design for High-Density Applications

With a 0.40mm pitch, this right-angle connector system offers the perfect balance between minimal footprint and high connection density, ensuring efficient space utilization on PCBs. This design is particularly valuable for applications where every millimeter counts, such as in consumer electronics, medical devices, and wearables. The friction lock mechanism ensures secure mating, minimizing the risk of accidental disconnections, making it suitable for high-vibration environments like automotive systems and industrial equipment.

As industries such as IoT, 5G technology, and smart devices rapidly evolve, there’s a growing need for connectors that support high-speed data transmission while remaining cost-effective. Molex addresses this demand with features like nickel-barrier plating that not only protects against flux wicking but also improves signal integrity—critical for high-frequency applications.

Durability and Ease of Assembly

In addition to space savings, these board-to-board connectors offer enhanced durability, ensuring long-lasting performance even in harsh conditions. The wide solder tabs and board-placement pegs provide stability during soldering, reducing errors and ensuring faster assembly times. This makes the connectors highly attractive for industries focusing on mass production and cost-efficient manufacturing, such as consumer electronics and automotive electronics.

The wide solder tabs provide additional PCB retention, offering a sturdy connection that resists mechanical stress. This is particularly important for devices that are subject to regular movement or vibration, such as portable medical devices, industrial controllers, and sensor modules.

Competitive Edge and Market Relevance
