Headers, Male Pins datasheet and documents for M20-9703946

M20-9703946

Headers, Male Pins Overview

The Harwin M20-9703946 is a card edge connector featuring 78 contacts arranged in two rows. It utilizes a 0.1-inch (2.54 mm) pitch and employs a right-angle configuration for board-to-board connections. The component uses solder terminals for secure attachment and features a black insulator. This male header design supports standard PCB mounting requirements within the M20 series.

Headers, Male Pins Feature Summary

Right-angle orientation facilitates compact vertical stacking of circuit boards.
Dual-row layout provides high-density signal routing capabilities.
Solder terminal construction ensures robust mechanical fixation to the substrate.

Headers, Male Pins Applications

Board-to-board interconnects requiring right-angle alignment
High-density signal routing in modular electronic assemblies
Vertical stacking configurations in compact hardware designs

Headers, Male Pins Procurement Notes

Verify the specific contact count and row configuration against project schematics, as the M20 series includes various pin counts. Confirm that the right-angle orientation matches the mechanical constraints of the assembly. Ensure the solder terminal type is compatible with the manufacturing process used for the target printed circuit board.

Headers, Male Pins Selection Notes

Select this component when a right-angle, dual-row connection is required for space-constrained applications. The 0.1-inch pitch offers compatibility with standard PCB layouts. Consider the mechanical stability provided by the solder terminals versus surface mount alternatives if vibration resistance is a primary concern for the final assembly environment.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which provides versatile PCB header solutions. The series includes both single and double-row options in various orientations. The M20-9703946 specifically addresses needs for high-contact density in a right-angle form factor, distinguishing it from straight or single-row variants within the same product family.
