M50-4302445

Headers, Receptacles, Female Sockets Overview

The Harwin M50-4302445 is a surface-mount board-to-board receptacle connector from the Archer M50 series. It features a dual-row configuration with 48 positions and a 1.27mm (0.05 inch) pin pitch. The connector utilizes gold-plated phosphor bronze contacts for reliable signal transmission. Designed for SMT installation, it has a profile height of 4.60mm and includes board guide rails to ensure precise alignment during mating. The housing is constructed from black liquid crystal polymer (LCP), offering high thermal stability and mechanical strength.

Headers, Receptacles, Female Sockets Feature Summary

• Dual-row surface-mount architecture with integrated board guide rails for accurate alignment
• Gold-plated phosphor bronze contacts ensuring durable electrical connectivity
• Liquid crystal polymer (LCP) housing providing robust thermal and mechanical performance

Headers, Receptacles, Female Sockets Applications

• High-density board-to-board interconnections in compact electronic modules
• Signal routing in telecommunications equipment requiring precise alignment
• Industrial control systems utilizing surface-mount assembly processes

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required 48-position dual-row specification. Confirm the surface-mount package type aligns with your PCB footprint design. Ensure compatibility with standard reflow soldering profiles suitable for LCP materials. Check for RoHS compliance documentation if required by your manufacturing standards.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-pin-count board-to-board connection is needed. The 1.27mm pitch allows for dense circuit layouts while maintaining reliable contact integrity. The shrouded design with guide rails minimizes misalignment risks during automated assembly. Consider the 4.60mm height constraint within your overall device enclosure dimensions.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to the Harwin Archer M50 series, designed for demanding applications requiring high reliability. The series offers various configurations including headers, sockets, and IDC connectors.
