Description

1mm spacing dual row female headers are fine-pitch PCB connectors designed for high-density applications where space is at a premium. These connectors feature 1.0mm pitch spacing (compared to the standard 2.54mm), allowing for significantly more connections in a smaller footprint. They are commonly used in compact electronics, embedded systems, industrial applications, and anywhere that high pin density is required. The dual row configuration maximizes pin count while maintaining mechanical stability.

Notes

These 1mm spacing dual row female headers are specialized components for high-density applications. They require careful PCB design, precise manufacturing, and skilled assembly. While more expensive and challenging to work with than standard 0.1” pitch headers, they enable significant space savings in compact designs. Essential for embedded systems, industrial controls, and any application where maximum pin density is required. Store carefully and handle with appropriate ESD precautions. Consider the total system cost including design, manufacturing, and assembly when specifying these connectors.
