Features and Benefits


Engineers are challenged with integrating multiple functions into a single module, while reducing its overall size and weight. They also want assurance that the components are robust enough to withstand the harsh conditions typical of automotive environments. Additionally, designers require systems that can seamlessly communicate with other vehicle components.

To address these concerns, engineers need products that enable design flexibility while adhering to compact design needs. They also need options for material selection and design practices that enhance durability.​ Also, connectors that adhere to industry standards and ensure designs are compatible with existing vehicle architectures add significant value for the success of automotive end products. 

Float Stack Connectors contribute to the overall success of vehicle designs. These board-to-board connectors offer a wide range of mating heights, providing the design flexibility needed to integrate multiple functions while minimizing device weight.​ Also, with two points of contact, Float Stack Connectors deliver increased contact reliability for exceptional anti-vibration performance and with their floating feature, provide additional reliability in harsh vibration environments. These connectors are USCAR V2 and LV214 compliant and ensure designs are compatible with existing vehicle architectures.

Tolerance Compensation

The Float Stack connector design supports high-current applications, while a large floating range of +0.75mm compensates for tolerance variations, enabling smooth automated assembly.
