Overview
The Harwin M20-7822646 is a 52-position dual-row socket assembly from the M20 series, designed for board-to-board applications. It features a 2.54 mm pitch and utilizes through-hole termination for secure PCB mounting. The connector employs nickel-plated tin contacts housed in a black nylon insulator, rated for operation between -40°C and +105°C. This vertical straight configuration supports high-density interconnects while maintaining reliable electrical performance in industrial environments.
Feature Summary
- Dual-row socket design optimized for board-to-board connectivity
- Through-hole termination ensures robust mechanical stability
- Vertical orientation facilitates compact circuit board stacking
Applications
- Industrial control systems requiring dense signal routing
- Communication equipment with multi-layer PCB architectures
- Automotive electronics utilizing standard 2.54mm spacing
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official Harwin documentation. Confirm that the specific suffix matches the required contact plating and housing material specifications. Ensure compatibility with mating pin headers before finalizing procurement orders to prevent interface mismatches.
Selection Notes
Select this model when a high-contact-count, dual-row solution is required for rigid board-to-board connections. The 2.54 mm pitch aligns with industry-standard spacing, simplifying layout design. Consider the through-hole mounting style for applications prioritizing mechanical durability over surface-mount space constraints.
Part Context
This component belongs to the Harwin M20 series, a widely adopted line of rectangular connectors known for their reliability in harsh environments. The series offers various configurations including single and double rows, with options for both through-hole and surface-mount terminations, catering to diverse electronic packaging needs.
Replacement Considerations
Direct substitutes within the same series include M20-7822946 (29-pin) or other variants with matching 2.54 mm pitch and dual-row socket characteristics. Verify pin count and housing dimensions to ensure mechanical fitment before substitution.
