M40-4012046R

Headers, Male Pins Overview

The M40-4012046R is a male header connector from the Harwin M40 series, designed for surface mount technology applications. It features a single row of twenty positions with a 1.00 mm pitch. The component utilizes a horizontal side-entry configuration and includes a shrouded housing with tab locks to secure mating cables. Constructed for reliable electrical connections in compact assemblies, it supports automated SMT assembly processes while maintaining signal integrity through precise pin alignment.

Headers, Male Pins Feature Summary

• Horizontal side-entry design facilitates efficient cable routing and board space optimization
• Shrouded housing structure provides mechanical stability and prevents misalignment during mating
• Tab lock mechanism ensures secure retention of connected wire harnesses

Headers, Male Pins Applications

• Compact consumer electronics assemblies requiring high-density interconnects
• Industrial control modules with limited vertical clearance constraints
• Automotive infotainment systems utilizing surface-mounted wiring solutions

Headers, Male Pins Procurement Notes

Verify the specific RoHS compliance status and lead times directly with authorized distributors or the manufacturer before ordering. Confirm that the surface mount footprint matches your PCB design requirements. Ensure compatibility with standard reflow soldering profiles to maintain connection reliability and prevent thermal damage to the plastic housing during assembly.

Headers, Male Pins Selection Notes

Select this part when a low-profile, single-row header is required for horizontal cable attachment. The 1.00 mm pitch allows for dense packing compared to larger spacing options. Consider the shrouded design if lateral stability is critical. Verify that the current rating and voltage specifications meet the circuit demands, as these are not explicitly detailed in general summaries but are inherent to the series design.

Headers, Male Pins Part Context

This component belongs to the M40 series, which focuses on fine-pitch connectivity solutions. The series offers various configurations including different pin counts and mounting styles. The M40-4012046R specifically addresses needs for horizontal, shrouded headers in space-constrained environments, providing a robust alternative to traditional vertical connectors in modern electronic manufacturing.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M40-4010446R (4-position) and M40-4011046R (10-position). For identical 20-position specifications, verify cross-references with other manufacturers offering 1.00 mm pitch SMT headers. Ensure mechanical dimensions and locking mechanisms match to avoid redesign efforts.
