Overview
The Harwin M20-7822746 is a 27-position double-row socket assembly from the M20 series. It features a 2.54 mm pitch and utilizes copper alloy contacts with gold plating for reliable signal transmission. The housing is constructed from high-temperature UL 94V-0 rated material, ensuring stability under thermal stress. Designed for board-to-board applications, this component supports jackscrew fixing mechanisms to secure connections in demanding environments.
Feature Summary
- Double-row configuration with jackscrew fixing for enhanced mechanical security
- High-temperature UL 94V-0 housing material for thermal resilience
- Gold-plated copper alloy contacts ensuring durable electrical performance
Applications
- Industrial control systems requiring robust interconnects
- Aerospace electronic assemblies
- Data center infrastructure hardware
Procurement Notes
Verify the specific contact plating thickness and housing color code against the official datasheet before ordering. Confirm that the jackscrew mechanism aligns with your panel mounting requirements. Ensure compatibility with mating headers regarding pin count and row spacing to prevent installation errors.
Selection Notes
Select this model when high mechanical retention is required via jackscrews rather than standard latching. It is suitable for designs needing superior thermal resistance compared to standard nylon housings. Consider the 27-position density for compact board-to-board layouts where space is limited but reliability is critical.
Part Context
This component belongs to the Harwin M20 series, known for industrial-grade connectivity solutions. The series offers various configurations including single and double rows with different fixing methods. This specific part represents a high-reliability option within the broader connector portfolio.
Replacement Considerations
Check for direct substitutes within the M20 series that may offer alternative fixing mechanisms or position counts. Verify cross-compatibility with existing mating connectors if considering alternative suppliers.
