M50-3550742

Headers, Male Pins Overview

The Harwin M50-3550742 is a male pin header from the Archer M50 series, featuring a 1.27 mm pitch and double row configuration with 7 positions. Designed for vertical through-hole mounting, it utilizes ejector pins to facilitate board removal. The connector supports a rated current of 1A and operates within a temperature range of -40°C to 105°C. It employs gold-plated phosphor bronze contacts housed in nylon insulation, ensuring reliable electrical performance in compact electronic assemblies.

Headers, Male Pins Feature Summary

• Incorporates integrated ejector pins to enable mechanical release of the connector from the mating socket during maintenance or replacement.
• Features vertical orientation design optimized for standard printed circuit board assembly processes.
• Utilizes high-conductivity gold-plated contacts on phosphor bronze substrates for stable signal transmission.

Headers, Male Pins Applications

• Compact consumer electronics requiring serviceable interconnects
• Industrial control modules needing reliable board-to-board connections
• Medical devices demanding secure and maintainable wiring harness interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and housing material grade against the official Harwin datasheet before finalizing procurement. Confirm that the ejector pin mechanism aligns with the mating socket's retention requirements. Ensure the selected variant matches the required current rating and thermal operating limits for the target application environment.

Headers, Male Pins Selection Notes

Select this component when a serviceable, low-profile connection is required in space-constrained designs. The ejector feature distinguishes it from standard headers, making it suitable for applications where frequent disassembly is anticipated. Ensure compatibility with mating sockets designed for 1.27 mm pitch double-row headers with ejection mechanisms.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer M50 series, a family of high-density connectors known for their reliability in harsh environments. The M50 series offers various configurations including IDC, wire-to-board, and board-to-board options, all sharing the consistent 1.27 mm pitch architecture for system-wide interoperability.

Headers, Male Pins Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires identical mechanical dimensions, ejector pin functionality, and electrical specifications from compatible manufacturers.
