M40-4010446R

Headers, Male Pins Overview

The Harwin M40-4010446R is a male pin header connector from the M40 series, designed for surface mount technology. It features a single row of four positions with a 1 mm (0.039 in) pitch. The connector utilizes a horizontal orientation and includes shrouded housing with SMT hold-down tabs to ensure secure board attachment during assembly. Rated for 50 V ac/dc and 1 A current, it employs matte tin contacts over a nickel barrier.

Headers, Male Pins Feature Summary

• Horizontal surface mount design with integrated hold-down tabs for mechanical stability
• Shrouded and polarized housing structure to prevent misalignment
• Single row configuration with 1 mm pitch for compact circuit integration

Headers, Male Pins Applications

• Surface mount interconnection on printed circuit boards
• Wire-to-board connections requiring horizontal alignment
• Compact electronic assemblies needing polarized header solutions

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'R' corresponds to tape and reel packaging requirements. Confirm that the horizontal orientation matches the PCB footprint design. Ensure compatibility with automated pick-and-place equipment due to the surface mount tab design. Check RoHS compliance documentation for regulatory adherence.

Headers, Male Pins Selection Notes

Select this component when a low-profile, horizontal connection is required for space-constrained designs. The 1 mm pitch allows for high density without sacrificing reliability. The shrouded design provides protection against accidental contact and ensures correct mating orientation. Suitable for applications where vertical headers are impractical.

Headers, Male Pins Part Context

This part belongs to the Harwin M40 series, which specializes in fine-pitch connectors. The series offers various configurations including vertical and horizontal options. The M40-4010446R specifically addresses needs for small form-factor electronics requiring robust surface mount connectivity with precise alignment features.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include other position counts like M40-4010246R or M40-4010846R. Verify that any replacement maintains the 1 mm pitch and horizontal orientation. Cross-model replacements require careful footprint and electrical rating validation.
