M20-9743542

Headers, Male Pins Overview

The Harwin M20-9743542 is a 70-position (35+35) double-row pin header from the M20 series. It features a 2.54 mm pitch and horizontal orientation for board-to-board connections. The connector utilizes gold-plated contacts with tin plating on specific sections, housed in a high-temperature UL 94V-0 nylon casing. Designed for through-hole mounting, it supports a current rating of 3A per contact and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Horizontal double-row configuration with secure latching mechanism
• High-temperature resistant housing meeting UL 94V-0 standards
• Mixed plating finish combining gold and tin for optimized conductivity

Headers, Male Pins Applications

• Board-to-board interconnections in industrial control systems
• High-density signal routing in telecommunications equipment
• Automotive electronic module interfaces requiring thermal stability

Headers, Male Pins Procurement Notes

Verify the exact pin count and row configuration against project requirements before ordering. Confirm that the mixed gold and tin plating specification aligns with the mating interface constraints. Ensure the horizontal mounting style fits within the available PCB real estate and clearance limits. Check for any specific handling instructions related to the latching mechanism during assembly.

Headers, Male Pins Selection Notes

Select this component when a high-density horizontal connection is required alongside robust thermal performance. The dual-row layout maximizes pin density while maintaining standard 2.54 mm spacing. Consider the mixed plating option if cost efficiency is needed without sacrificing critical contact reliability. Ensure the through-hole footprint matches the target PCB design rules.
