M22-2042005

Headers, Male Pins Overview

The M22-2042005 is a 40-position, dual-in-line male pin header from the Harwin M22 series. It features a 2.00mm (0.079 inch) pitch and is designed for right-angle, through-hole mounting on printed circuit boards. The connector utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. It operates within a temperature range of -40°C to +105°C and supports a current rating of 1A per contact. The unit includes a rectangular contact pattern and offers mechanical durability rated for 300 mating cycles.

Headers, Male Pins Feature Summary

• Features a 2.00mm pitch male pin connection system for board-to-board applications
• Constructed with phosphor bronze contacts finished in gold for corrosion resistance
• Designed for right-angle through-hole installation with a cuttable strip format
• Utilizes UL94V-0 rated plastic insulation for thermal stability

Headers, Male Pins Applications

• Board-to-board interconnections requiring high-density routing
• Industrial control systems operating in moderate thermal environments
• Test and measurement equipment interfaces
• General electronic assemblies needing reliable signal paths

Headers, Male Pins Procurement Notes

Verify that the specific order matches the M22-2042005 part number exactly, as the M22 series contains numerous variants with different pin counts and orientations. Confirm that the required current rating of 1A aligns with the application's electrical load requirements. Ensure that the right-angle through-hole mounting style is compatible with the target PCB layout and assembly process. Check for RoHS compliance documentation if environmental regulations apply to the final product deployment.

Headers, Male Pins Selection Notes

Select this component when a rigid, right-angle male header is required for permanent board connections. The 2.00mm pitch allows for higher density compared to standard 2.54mm headers. Consider the gold plating for improved conductivity and oxidation resistance over tin alternatives. Evaluate the 300-cycle durability against expected maintenance or rework frequencies. Ensure the 1A current rating suffices for all connected circuits without derating issues.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, which specializes in 2.00mm pitch connectors. The series is known for its robust mechanical design and square pin contact system. The M22-2042005 specifically represents a 40-position variant, providing a balance between connectivity density and physical footprint. It is distinct from the M20 series, which typically features smaller pitches and different contact geometries.

Headers, Male Pins Replacement Considerations

M22-2412042 is listed as a potential substitute in distributor records, though it may be end-of-life. Verify compatibility regarding pin count, pitch, and orientation before substitution. No other direct cross-model replacements are confirmed in public data.
