M20-7832842

Overview

The M20-7832842 is a card edge connector manufactured by Harwin Inc., designed for surface mount applications. It features a dual-row configuration with 56 contact positions and a standard 0.1-inch (2.54mm) pitch. The connector utilizes female contacts suitable for mating with card edge PCBs. Constructed with a black insulator, it employs solder terminals for secure board attachment. This component belongs to the M20 series, offering reliable interconnection in compact electronic assemblies requiring high-density pin counts.

Feature Summary

• Dual-row female contact design for card edge interface
• Surface mount termination method for automated assembly
• Standard 0.1 inch pitch for broad compatibility

Applications

• Industrial control systems
• Telecommunications equipment
• Consumer electronics modules

Procurement Notes

Verify the specific datasheet version for precise mechanical dimensions and plating thickness requirements before integration. Confirm that the target card edge PCB thickness aligns with the connector's retention specifications. Ensure compliance with RoHS directives if required by the end product regulations. Cross-reference the pin count and row configuration against the schematic to prevent mismatch errors during procurement.

Selection Notes

Select this model when a high-density 56-position interface is required on a single footprint. The dual-row layout maximizes signal capacity within limited board areas. Consider the surface mount profile for low-profile design constraints. Evaluate the mechanical locking features provided by the series to ensure stability during vibration or thermal cycling in the final application environment.
