M52-040000S2045

Headers, Male Pins Overview

The Harwin M52-040000S2045 is a 20-position single-row male pin header from the Archer M52 series. It features a 1.27 mm (0.05 in) contact pitch and utilizes surface mount technology for PCB attachment. The connector system is designed for board-to-board applications with an unshrouded configuration. Contacts are made of brass with gold plating, rated for 1 A current. The housing is constructed from black nylon. Operating temperatures range from -40°C to +105°C. Tail dimensions include a 2.54 mm length.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' confirms the surface mount tail configuration and '2045' denotes the 20-position count with 2.54mm tail length. Ensure compatibility with standard reflow soldering profiles. Confirm that the unshrouded design meets spatial constraints within the target enclosure. Cross-reference the manufacturer datasheet for precise mechanical tolerances before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when high-density board-to-board connectivity is required with surface mount constraints. The 1.27 mm pitch allows for compact layouts compared to standard 2.54 mm headers. Consider the unshrouded nature for mating clearance requirements. Verify that the 1 A current rating suffices for the application's electrical load. Ensure the operating temperature range aligns with environmental conditions.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer M52 series, which focuses on high-density interconnect solutions. The series offers various row counts and tail lengths to accommodate different stacking heights. The M52 series is characterized by its robust construction and suitability for demanding industrial environments. It provides a reliable alternative to through-hole connectors in space-constrained designs.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 20 positions, and SMT mounting style. Verify identical tail lengths and contact materials for interchangeability. Generic equivalents may lack the specific gold plating thickness or nylon housing specifications. Always validate mechanical fit and electrical ratings against the original datasheet before substitution.
