M50-4804245

Headers, Male Pins Overview

The Harwin M50-4804245 is a board-to-board connector from the Archer M50 series, designed for surface-mount technology (SMT) applications. It features a dual in-line configuration with 42 positions arranged in two rows of 21 contacts each. The connector utilizes a 1.27 mm pitch and incorporates a shrouded design to ensure precise alignment during mating. Contacts are gold-plated copper alloy pins, providing reliable electrical performance. The housing is constructed from black thermoplastic material rated UL 94 V-0 for flammability. This component operates within a temperature range of -40°C to +105°C and supports a current rating of 1 A per contact.

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required termination style and packaging format. Confirm compliance with RoHS directives and lead-free requirements for environmental standards. Ensure compatibility with existing PCB footprint dimensions and reflow soldering profiles. Check for any updated datasheet revisions that may affect mechanical tolerances or material specifications before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required between adjacent printed circuit boards. The 1.27 mm pitch allows for significant I/O density within limited board areas. Consider the shrouded feature if lateral guidance is critical for assembly accuracy. Evaluate the 1 A current rating against the total power dissipation requirements of the target application to ensure safe operational margins.

Headers, Male Pins Part Context
