M40-3010346R

Headers, Male Pins Overview

The M40-3010346R is a surface mount pin header from the Harwin M40 series, designed for wire-to-board connections. It features a single row of three male contacts with a 1 mm (0.039 inch) pitch. The connector utilizes a straight orientation and includes a shrouded housing with polarized design to ensure correct mating alignment. The terminals are finished with matte tin over a nickel barrier, providing reliable soldering performance on printed circuit boards.

Headers, Male Pins Feature Summary

• Shrouded and polarized housing design ensures precise alignment during assembly
• Surface mount construction with hold-down tabs for secure PCB attachment
• Single row configuration with straight male pins for direct board connection

Headers, Male Pins Applications

• Wire-to-board interconnections in compact electronic assemblies
• Signal transmission in space-constrained consumer electronics
• Industrial control modules requiring reliable surface mount headers

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'R' against official Harwin documentation to confirm the presence of hold-down tabs and shrouding details. Ensure compatibility with mating wire harnesses by checking terminal dimensions and insulation types. Confirm RoHS compliance status through current manufacturer declarations prior to procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row surface mount header is required for 1 mm pitch applications. Consider the shrouded design for environments where misalignment risks exist. Evaluate the straight orientation against available board space and mating cable routing requirements to ensure mechanical fit.

Headers, Male Pins Part Context

This part belongs to the M40 series, characterized by its 1 mm pitch and surface mount capabilities. The series offers various contact counts and configurations, making it suitable for diverse connectivity needs.
