Overview
The Harwin M20-7823146 is a 31-position socket assembly from the M20 series, designed for board-to-board applications. It features a 2.54 mm (0.1 in) pitch and utilizes a single-row configuration. The connector employs through-hole termination with a tin-plated contact finish to ensure reliable electrical connections. Constructed as a receptacle, it is intended for vertical mounting on printed circuit boards.
Feature Summary
- Single-row receptacle design optimized for high-density PCB layouts
- Through-hole termination method ensures secure mechanical fixation
- Tin-plated contacts provide corrosion resistance and conductivity
Applications
- Board-to-board interconnection systems
- Industrial control unit signal routing
- High-density electronic module integration
Procurement Notes
Verify component authenticity against official Harwin documentation due to potential obsolescence or supply chain variations. Confirm that the specific ordering suffix matches the required pin count and plating specifications. Ensure compatibility with mating header assemblies within the same M20 series family before finalizing procurement orders.
Selection Notes
Select this component when a 31-position single-row interface is required for direct board-to-board connection. The 2.54 mm pitch aligns with standard industrial spacing requirements. Consider the through-hole mounting style for robust mechanical stability in environments subject to vibration or thermal cycling.
Part Context
This part belongs to the Harwin M20 series, which offers various configurations including straight and right-angle headers. The series is characterized by its compact footprint and reliability for general-purpose electronic interconnects. The M20-7823146 specifically addresses the need for higher pin counts in a single-row format.
Replacement Considerations
Consult official Harwin resources for confirmed substitute part numbers. Verify that any replacement maintains the 2.54 mm pitch, 31-position count, and single-row receptacle form factor to ensure mechanical and electrical compatibility.
