M50-3552542

Headers, Male Pins Overview

The Harwin M50-3552542 is a male header connector from the Archer M50 series, designed for board-to-board and wire-to-board applications. It features a 1.27 mm pitch with 50 positions arranged in two rows. The connector utilizes through-hole termination and includes an ejector latch mechanism for secure mating. Constructed with gold-plated phosphor bronze contacts and UL94V-0 rated LCP housing, it supports 500V voltage ratings and operates within a temperature range of -55°C to +125°C.

Headers, Male Pins Feature Summary

• Ejector latch mechanism ensures secure connection and facilitates easy disengagement
• Gold-plated phosphor bronze contacts provide reliable conductivity and corrosion resistance
• High-temperature LCP housing offers superior thermal stability and UL94V-0 flammability rating

Headers, Male Pins Applications

• Board-to-board interconnections in high-density electronic assemblies
• Wire-to-board connections requiring robust mechanical retention
• Industrial control systems operating in elevated temperature environments

Headers, Male Pins Procurement Notes

Verify that the specific part number M50-3552542 matches the required 50-position, dual-row configuration with an integrated ejector latch. Confirm that the through-hole mounting style and LCP housing material are compatible with your PCB design and thermal requirements. Ensure compatibility with mating connectors in the Archer M50 series to guarantee proper alignment and electrical performance.

Headers, Male Pins Selection Notes

Select this component when high reliability and secure mechanical retention are critical. The ejector latch feature distinguishes it from standard headers, making it suitable for applications where vibration resistance and ease of maintenance are priorities. Consider the 1.27 mm pitch constraint and the need for through-hole assembly when evaluating alternative connector options.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, which is engineered for demanding industrial and commercial applications. The series is characterized by its compact 1.27 mm pitch, high current carrying capacity, and robust construction materials. The M50-3552542 specifically integrates an ejector latch, enhancing its utility in dense packaging scenarios where secure locking is essential.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 1.27 mm pitch, 50-position count, dual-row layout, and ejector latch functionality. Verify that any replacement part shares the same through-hole termination method and compatible housing material properties to ensure mechanical and electrical interchangeability.
