M22-2541905

Headers, Male Pins Overview

The M22-2541905 is a Harwin Inc. connector header in the M22 series, designed for through-hole mounting with right-angle termination. It features a double-row configuration with 38 total positions (19+19) and a 2.00mm pitch. The contacts are gold-plated phosphor bronze pins, rated for 1A per contact. The housing is black polyamide (PA6T) with UL94 V-0 flammability rating, supporting an operating temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Double-row design with jackscrew fixing mechanism for secure board-to-board connection
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• High-temperature resistant PA6T insulation material meets UL94 V-0 standards

Headers, Male Pins Applications

• Board-to-board interconnections in industrial equipment
• Signal routing in high-density electronic assemblies
• Automotive control unit interfaces requiring robust latching

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm contact plating and row configuration. Ensure compatibility with mating sockets from the same M22 family. Confirm that the right-angle orientation matches the PCB layout requirements. Check for any updated environmental compliance declarations prior to final procurement approval.

Headers, Male Pins Selection Notes

Select this model when a double-row, right-angle header with jackscrew retention is required. The 2.00mm pitch suits applications needing moderate pin density. Gold plating is preferred for signal integrity over tin variants. Ensure the PCB hole pattern aligns with the 19+19 DIL specification.

Headers, Male Pins Part Context

Part of the Harwin M22 Datamate L-Tek series, known for mixed-signal capabilities. The M22-254xx series specifically denotes horizontal headers. This component complements mating receptacles like the M22-634 or M22-636 series. It serves as a critical interface node in modular electronic systems.

Headers, Male Pins Replacement Considerations

M22-2541946 is a similar horizontal header but uses tin plating instead of gold. Verify if the reduced cost of tin plating is acceptable for the application environment. No direct cross-brand substitutes are officially confirmed.
