M50-4304945

Headers, Receptacles, Female Sockets Overview

Harwin Inc. M50-4304945 is a board-to-board receptacle from the ARCHER M50 series, designed for surface-mount technology (SMT) assembly. This component features a dual-row configuration with a total of 98 positions, arranged as 49+49 contacts. It utilizes a 1.27 mm pitch and a 1.27 mm row spacing to facilitate high-density interconnections. The connector employs gold-plated phosphor bronze contacts housed in a black thermoplastic body. With a maximum height of 4.60 mm, it supports vertical mating applications while maintaining compliance with RoHS standards and offering moisture sensitivity level 1 classification.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific manufacturer datasheet for the M50-4304945 to confirm current production status and detailed mechanical drawings. Ensure that the receiving PCB footprint matches the specified 1.27 mm pitch and row spacing dimensions. Check for any updated environmental compliance certificates required by your region. Confirm that the soldering profile aligns with the thermal characteristics of the gold-plated contacts and thermoplastic housing to prevent damage during reflow processes.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-pin-count, low-profile vertical connection is required between two printed circuit boards. The 1.27 mm pitch allows for significant I/O density within a constrained area. Consider the 4.60 mm height relative to surrounding components to ensure adequate clearance. The gold plating is suitable for environments where corrosion resistance and low contact resistance are critical for long-term reliability.
