M20-9734045

Headers, Male Pins Overview

The M20-9734045 is a single-row pin header from the Harwin M20 series, designed for through-hole mounting. It features 40 positions with a 2.54 mm pitch and straight installation angle. The connector utilizes male pins with gold plating and a black nylon housing. Rated for 3 A current and 750 V voltage, it operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Single row configuration for compact board-to-board or wire-to-board connections
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Black nylon housing provides structural integrity and insulation
• Through-hole solder pin termination supports robust PCB attachment

Headers, Male Pins Applications

• Industrial control systems requiring high-density interconnects
• Consumer electronics utilizing standard 2.54 mm spacing
• Automotive electronic modules operating in varied thermal environments
• Test and measurement equipment interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish against project requirements, as M20 series variants may differ between tin and gold options. Confirm that the single-row, 40-position specification aligns with the target PCB footprint. Ensure compatibility with mating sockets from the same M20 family to maintain mechanical and electrical integrity during assembly.

Headers, Male Pins Selection Notes

Select this component when a single-row, 40-pin interface is required with gold contact plating for enhanced durability. The 2.54 mm pitch ensures compatibility with standard prototyping and production PCBs. Consider the 750 V rating and 3 A current capacity for appropriate circuit loading. Verify that the straight, through-hole mounting style fits the enclosure constraints.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of connectors known for their reliability in harsh environments. The M20 series offers various configurations including single and double rows with different pin counts. This specific model represents the high-contact-count single-row variant, providing a dense connection solution for complex electronic assemblies.

Headers, Male Pins Replacement Considerations

M20-9734046 serves as a vertical alternative within the same series. For tin-plated equivalents, verify specific suffixes in the M20 catalog. Cross-reference with other manufacturers offering 2.54 mm pitch headers if supply chain constraints exist, ensuring identical mechanical dimensions and electrical ratings.
