M20-9750442

Headers, Male Pins Overview

The M20-9750442 is a Harwin M20 series board connector featuring a single row of four male pin headers. It utilizes a 2.54 mm (0.1 inch) pitch and is designed for horizontal orientation to facilitate 90-degree board-to-board applications. The contacts are constructed from brass with gold plating, while the housing is made of nylon. This component supports through-hole termination and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Horizontal pin header configuration optimized for 90-degree board-to-board interconnections
• Gold-plated brass contacts ensure reliable electrical performance in single-row layouts
• Nylon housing provides structural integrity for surface or through-hole mounting

Headers, Male Pins Applications

• 90-degree board-to-board connections
• Interconnecting circuit boards at right angles
• Compact electronic assemblies requiring horizontal header profiles

Headers, Male Pins Procurement Notes

Verify the specific contact plating and terminal type against official datasheets, as distributor listings may vary. Confirm that the horizontal orientation matches the mechanical requirements for 90-degree mating. Ensure compatibility with corresponding female connectors or jumper sockets specified by the manufacturer for proper engagement.

Headers, Male Pins Selection Notes

Select this component when a low-profile horizontal header is required for perpendicular board stacking. The single-row design suits applications with limited width constraints. Verify that the mating interface accepts male pins and that the board layout accommodates the specific footprint dimensions associated with the M20 series.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of board-to-board and wire-to-board connectors. The series offers various configurations including vertical, horizontal, and angled options in single and double rows. The M20-9750442 specifically addresses the need for horizontal mounting solutions within this standardized ecosystem.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other M20 series horizontal headers such as M20-9712042 or M20-9740442, provided they match the required position count and orientation. Always verify mechanical dimensions and mating compatibility before substitution.
