M40-4010846R

Headers, Male Pins Overview

The Harwin M40-4010846R is a male pin header from the M40 series, featuring an 8-position configuration with a 1 mm pitch. It utilizes a single-row (SIL) design intended for surface mount technology (SMT) horizontal installation. The connector incorporates a shrouded and polarized polyamide housing with SMT hold-down tabs to ensure secure board attachment. Contacts are constructed from tin over nickel-plated phosphor bronze, providing reliable electrical performance in compact interconnect applications.

Headers, Male Pins Feature Summary

• Shrouded and polarized housing design prevents misalignment during assembly
• Surface mount hold-down tabs provide mechanical stability on the PCB
• Tin over nickel-plated phosphor bronze contacts ensure durability

Headers, Male Pins Applications

• Compact electronic device interconnections
• Board-to-cable or wire connections
• Space-constrained consumer electronics assemblies

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the component matches the required surface mount orientation and pin count for your specific circuit design. Ensure compatibility with automated pick-and-place equipment due to the reel packaging format.

Headers, Male Pins Selection Notes

Select this component when a low-profile, horizontally mounted header is required for space-limited designs. The 1 mm pitch allows for high-density connections while maintaining reliable signal integrity. Consider the shrouded design if polarization and protection against incorrect mating are critical requirements for the assembly process.
