M50-3903142

Headers, Male Pins Overview

The Harwin M50-3903142 is a 62-position dual-in-line pin header from the Archer M50 series. It features a 1.27 mm pitch and two rows of contacts designed for through-hole mounting. The connector utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. Constructed with a black polybutylene terephthalate (PBT) housing, it supports a maximum operating temperature of 105°C and a minimum of -40°C. Rated for 1A current, this component provides secure board-to-board or wire-to-board interconnections in compact electronic assemblies.

Headers, Male Pins Feature Summary

• Dual-row configuration with 1.27 mm spacing for high-density circuit integration
• Gold-plated phosphor bronze contacts for durable electrical conductivity
• Through-hole termination style ensuring stable mechanical PCB attachment
• Black PBT housing material providing thermal stability up to 105°C

Headers, Male Pins Applications

• Industrial control systems requiring robust board-to-board connections
• Medical equipment utilizing high-reliability signal interconnects
• Automotive electronics demanding stable performance under vibration
• Test and measurement instrumentation needing precise signal routing

Headers, Male Pins Procurement Notes

Verify the specific contact count and row configuration against the official Harwin datasheet before ordering. Confirm that the through-hole mounting style aligns with your PCB fabrication capabilities. Ensure the 1.27 mm pitch matches the mating connector specifications to prevent assembly errors. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Headers, Male Pins Selection Notes

Select this component when a high-density, dual-row connection is required on a single-sided or double-sided PCB. The 1.27 mm pitch allows for significant I/O density within limited board space. Consider the 1A current rating for signal integrity rather than high-power applications. The straight orientation suits standard vertical stacking or direct panel mounting scenarios.
