Overview
The M20-7850542 is a Harwin M20 series socket assembly featuring 10 positions arranged in a dual in-line configuration. It utilizes a 2.54 mm pitch and is designed for through-hole mounting with solder termination. The connector supports both bottom and top entry orientations, offering flexible integration options. Contact surfaces are finished with tin plating to ensure reliable electrical connections within the specified operating temperature range.
Feature Summary
- Dual in-line receptacle design accommodating two rows of contacts
- Supports versatile board integration via selectable bottom or top entry paths
- Through-hole solder termination ensures secure mechanical attachment
Applications
- General-purpose electronic interconnect systems
- Industrial control module signal routing
- Consumer electronics internal wiring harnesses
Procurement Notes
Verify component authenticity against official Harwin documentation prior to integration. Confirm that the tin-plated contact finish aligns with your system's corrosion resistance requirements. Ensure PCB layout accommodates the specific dual in-line footprint and entry orientation constraints defined in the datasheet.
Selection Notes
Select this model when a low-profile, dual-row female connector is required for standard pitch applications. The tin finish offers cost-effective conductivity suitable for non-high-frequency environments. Consider the through-hole requirement during PCB fabrication planning to ensure adequate clearance for soldering operations.
Part Context
This component belongs to the Harwin M20 family, known for compact rectangular connectors. It serves as a complementary counterpart to male pin headers within the same series, enabling standardized mating interfaces across various product lines while maintaining consistent dimensional tolerances.
Replacement Considerations
M20-7850546 is a documented alternative within the M20 series. Verify compatibility regarding contact material and entry orientation before substitution.
