M20-7832042

Overview

The M20-7832042 is a dual in-line vertical socket assembly from the Harwin M20 series, designed for board-to-board or cable connections. It features a 2.54mm (0.100 inch) pitch with 40 positions arranged in two rows. The connector utilizes square contacts made of phosphor bronze, finished with gold plating on the mating interface and tin on the tail. It supports a rated current of 3A per contact and a voltage rating of 1000V. The housing is constructed from black polyamide (PA6T/nylon 6T) with an insulation height of 8.51mm and a UL94 V-0 flammability rating. Operating temperatures range from -40°C to 105°C.

Feature Summary

• High-voltage capability with a 1000V rating suitable for demanding industrial applications
• Robust construction using PA6T insulation material for enhanced thermal stability
• Gold-plated square contacts ensure reliable signal transmission and low contact resistance
• Vertical through-hole design facilitates standard PCB mounting processes

Applications

• Industrial control systems requiring high-voltage isolation
• Telecommunications equipment interfaces
• General-purpose electronic assemblies needing robust board-to-board connectivity

Procurement Notes

Verify component authenticity by checking the manufacturer part number against official Harwin documentation. Confirm that the specific suffix matches the required contact finish and housing color specifications. Ensure compliance with RoHS directives if applicable to your manufacturing environment. Cross-reference the datasheet for any recent updates regarding lead-free soldering profiles or storage conditions to maintain connector integrity during assembly.

Selection Notes

Select this component when a vertical, through-hole socket with high-voltage ratings is required. The 40-position configuration suits applications needing dense interconnects without excessive board space usage. Consider the 1000V rating for safety margins in power distribution circuits. Verify that the 2.54mm pitch aligns with the mating header dimensions and that the PCB hole pattern accommodates the specified contact length and tail geometry for proper solder joint formation.

Part Context

This socket assembly belongs to the M20 series, a family of connectors known for their versatility in various electronic environments. The M20 line offers multiple configurations including surface mount and through-hole options with varying pin counts. This specific model represents a standard dual-in-line variant optimized for reliability in harsh conditions, complementing matching headers within the same product ecosystem for consistent mechanical and electrical performance.
