M50-4902445

Headers, Male Pins Overview

The Harwin M50-4902445 is a surface-mount shrouded header from the ARCHER series, designed for high-density interconnects. It features a 1.27 mm pitch and a dual-row configuration with 48 positions. The connector utilizes gold-plated brass contacts rated for 1 A current and 300 V voltage. Constructed with a black liquid crystal polymer (LCP) housing, it supports a straight installation angle and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Shrouded four-wall design ensures precise mating alignment and protects contacts during assembly.
• Gold plating on brass contacts provides reliable conductivity and corrosion resistance.
• Liquid crystal polymer insulation offers high thermal stability and UL 94 V-0 flammability rating.

Headers, Male Pins Applications

• High-density board-to-board connections in compact electronic modules
• Signal routing in telecommunications equipment requiring stable SMT interfaces
• Industrial control systems utilizing robust surface-mount header arrays

Headers, Male Pins Procurement Notes

Verify the specific pin count and row configuration against the datasheet before ordering, as the M50 series contains numerous similar part numbers. Confirm that the surface-mount footprint matches the target PCB layout. Check for end-of-life status or discontinuation notices, as availability may vary significantly across distributors. Ensure compatibility with automated pick-and-place equipment specifications.

Headers, Male Pins Selection Notes

Select this component when a low-profile, double-row surface-mount header is required for dense signal routing. The 1.27 mm pitch allows for higher connection density compared to standard 2.54 mm headers. Choose this model if gold-plated contacts are necessary for signal integrity in low-voltage applications. Consider the LCP material properties for environments requiring elevated thermal performance during soldering.
