M50-3552042

Headers, Male Pins Overview

The Harwin M50-3552042 is a 1.27mm pitch dual-in-line connector header from the Archer M50 series, featuring 40 positions arranged in two rows. Designed for vertical through-hole mounting, it incorporates an ejector mechanism with PC tails and a latch system for secure mating. The contacts are male pins made of phosphor bronze with gold plating, rated for 500mA at 250V. It supports wire-to-board applications within an operating temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical through-hole mounting configuration with integrated ejector mechanism
• Male pin contacts with gold plating for reliable signal transmission
• Latch system ensures secure connection during operation

Headers, Male Pins Applications

• Wire-to-board interconnections
• High-density electronic assemblies requiring secure locking
• Industrial control systems needing robust connectors

Headers, Male Pins Procurement Notes

Verify the specific suffix '42' corresponds to the required contact count and row configuration against official datasheets. Confirm that the ejector and latch features are necessary for the mechanical design, as these add complexity compared to standard headers. Ensure compatibility with mating receptacles from the same M50 series family.

Headers, Male Pins Selection Notes

Select this component when a secure, latched connection is required for high-density wiring. The vertical orientation and ejector feature simplify assembly and maintenance. Consider the 500mA current rating and 1.27mm pitch constraints relative to board space and electrical requirements compared to higher-current or larger-pitch alternatives.

Headers, Male Pins Part Context

This part belongs to the Archer M50 series, known for its compact 1.27mm pitch and robust construction. The M50-3552042 specifically addresses needs for secure, removable connections in dense layouts, distinguishing itself from standard headers by including mechanical retention features like ejectors and latches.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M50 series headers with matching 40-position, 2-row configurations and similar mechanical features. Verify pitch, mounting style, and contact type before substitution.
