M50-3902042

Headers, Male Pins Overview

The Harwin M50-3902042 is a 40-position male pin header from the Archer M50 series, featuring a 1.27 mm pitch and two rows of contacts. Designed for through-hole installation with right-angle orientation, it utilizes phosphor bronze contacts gold-plated for conductivity. The housing is constructed from liquid crystal polymer (LCP), supporting operating temperatures between -40°C and +105°C. Rated for 1A current and 500V AC, this connector system facilitates board-to-board and wire-to-board connections.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting configuration for compact PCB integration
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• Liquid crystal polymer housing providing high thermal stability

Headers, Male Pins Applications

• Board-to-board interconnections in industrial control systems
• Wire-to-board connections in consumer electronics assemblies
• High-density signal routing in telecommunications equipment

Headers, Male Pins Procurement Notes

Verify that the specific part number M50-3902042 matches the required 40-pin, right-angle, through-hole specification. Confirm compatibility with mating sockets within the Archer M50 series to ensure correct pitch and row alignment. Check for RoHS compliance requirements if applicable to your manufacturing standards. Ensure the selected variant meets the necessary current and voltage ratings for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a right-angle male header is required for space-constrained designs. The 1.27 mm pitch allows for high density without sacrificing electrical isolation. Consider the LCP material properties for applications involving higher thermal loads during soldering or operation. Ensure the PCB layout accommodates the right-angle tail dimensions and through-hole drilling specifications.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, known for its robust performance in demanding environments. The series offers various configurations including straight and right-angle headers, as well as IDC options. The M50-3902042 specifically addresses needs for horizontal male pin strips with selective gold and tin plating on the contacts.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same family include other pin counts such as M50-3802042. Verify that any replacement maintains the identical 1.27 mm pitch, 2-row configuration, and right-angle orientation to ensure mechanical and electrical compatibility.
