M50-4902845

Headers, Male Pins Overview

The M50-4902845 is a surface-mount pin header from the Harwin Archer M50 series. It features 56 positions arranged in a dual inline configuration with two rows. The connector utilizes a 1.27 mm (0.05 inch) pitch for both contact and row spacing. Contacts are gold-plated phosphor bronze pins designed for solder termination. The housing is constructed from black liquid crystal polymer (LCP) with UL 94 V-0 flammability rating. It operates within a temperature range of -40°C to +105°C and supports a current rating of 1 A per contact.

Headers, Male Pins Feature Summary

• Four-wall shrouded design provides mechanical alignment and protection during board-to-board mating.
• Push-pull locking mechanism ensures secure connection retention between assembled boards.
• Square contact shape enhances stability and prevents rotation within the housing.
• Gold plating on contacts ensures reliable signal transmission and corrosion resistance.

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic assemblies
• High-density signal routing in telecommunications equipment
• Industrial control systems requiring robust surface-mount headers

Headers, Male Pins Procurement Notes

Verify component status as this part is classified as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Check for valid replacement part numbers such as SBH31-NBPB-D28-SM-BK if sourcing new production units is required. Ensure compatibility with existing PCB footprints before procurement.

Headers, Male Pins Selection Notes

Select this component only if the specific 56-position, 1.27mm pitch SMT form factor is mandatory for the design. Consider the four-wall shroud and push-pull lock requirements against alternative standard headers. Evaluate the obsolete status impact on long-term supply chain stability and potential redesign needs.
