M20-7921042R

Overview

The Harwin M20-7921042R is a 20-position receptacle connector from the M20 series, designed for surface-mount applications. It features a right-angle package with a 0.100 inch (2.54 mm) pitch. The contacts are gold-plated to ensure reliable signal transmission. This component serves as a female socket assembly, intended for board-to-board or cable connections in electronic systems requiring robust interconnect solutions.

Feature Summary

• Right-angle surface-mount design for compact PCB integration
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• 20-position configuration with standard 2.54 mm spacing

Applications

• Board-to-board interconnections
• Cable-to-board assemblies
• High-density electronic modules

Procurement Notes

Verify the specific suffix 'R' indicates the right-angle orientation during procurement. Confirm RoHS compliance status through official datasheets. Ensure compatibility with mating header pins of matching pitch and contact count. Check for end-of-life notices as availability may vary by region.

Selection Notes

Select this model when right-angle mounting is required for space-constrained designs. The 20-position count suits moderate density needs. Gold plating is preferred for environments requiring high reliability. Verify that the surface-mount footprint matches the target PCB layout constraints.

Part Context
