Overview
The M20-7821846 is a Harwin M20 series header socket assembly designed for board-to-board applications. It features a dual in-line configuration with 18 positions arranged in a single row. The connector utilizes a 2.54 mm pitch and employs vertical through-hole termination for secure PCB mounting. Contact surfaces are finished with tin plating to ensure reliable signal transmission. This component serves as a standard interconnection solution within the M20 product family.
Feature Summary
- Dual in-line socket assembly structure
- Vertical through-hole termination method
- Tin-plated contact surface finish
Applications
- Board-to-board interconnection systems
- Industrial electronic assemblies
- General purpose circuit integration
Procurement Notes
Verify the specific pin count and termination style against design requirements before ordering. Confirm that the tin plating specification meets the environmental and conductivity needs of the target application. Ensure compatibility with mating headers from the same M20 series to maintain mechanical alignment and electrical integrity during assembly processes.
Selection Notes
Select this component when a single-row, 18-position vertical header is required. The 2.54 mm pitch ensures compatibility with standard PCB layouts. Consider the tin plating for general use cases where gold plating is not strictly necessary. Verify that the through-hole mounting method aligns with the manufacturing capabilities and structural constraints of the final assembly design.
Part Context
This part belongs to the Harwin M20 series, which provides industrial standard connectors. The series offers various configurations including different pin counts and termination types. The M20-7821846 specifically addresses needs for moderate density connections using a single row format. It represents a standard offering within the broader range of board-to-board interconnect solutions provided by the manufacturer.
Replacement Considerations
