M20-7832246

Overview

The Harwin M20-7832246 is a 40-position, dual-row PCB socket connector from the M20 series. It features a 2.54 mm pitch and utilizes vertical through-hole termination for board-to-board applications. The housing is constructed from high-temperature liquid crystal polymer rated UL94V-0, ensuring compatibility with surface mount reflow processes. Contacts are made of bronze with nickel plating and tin overplating to provide durable electrical connections. The component supports a current rating of 12A and operates within a temperature range of -40°C to 105°C.

Feature Summary

Dual-beam contact design improves electrical connection reliability
High-temperature LCP housing withstands SMT reflow profiles
Vertical orientation facilitates dense PCB mounting

Applications

Board-to-board interconnections in industrial electronics
High-density PCB assembly requiring robust mechanical stability
Automotive control modules operating in extreme temperatures

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm pin count and termination style. Ensure the ordering quantity matches the required package configuration. Confirm RoHS compliance status if restricted substances are a project constraint. Cross-reference the manufacturing date code to ensure component freshness. Validate that the supplier provides original manufacturer documentation.

Selection Notes

Select this model when a 40-pin dual-row interface is required for rigid board stacking. The vertical form factor suits applications with limited lateral space but available height. Verify that the mating header pins align with the 2.54 mm grid standard. Consider the thermal resistance of the LCP housing for high-heat environments.

Part Context

This component belongs to the Harwin M20 series, which offers industrial-grade connectivity solutions. The series is characterized by compact designs suitable for modern PCB density requirements. These connectors are engineered for durability and consistent performance across various electronic systems.
