Overview
The M20-7850646 is a socket assembly from the Harwin M20 series, designed for wire-to-board and board-to-board interconnections. It features a single row with 12 positions and a 2.54 mm pitch. The connector utilizes a through-hole termination method with a bottom entry configuration. The housing is constructed from nylon, while contacts are made of brass with tin plating. This component supports standard PCB mounting techniques for reliable signal transmission.
Feature Summary
- Single-row receptacle design for compact circuit layouts
- Bottom entry contact orientation for streamlined wiring
- Tin-plated brass contacts for corrosion resistance
- Nylon housing material providing structural stability
Applications
- Wire-to-board connections in industrial control systems
- Board-to-board interconnects in consumer electronics
- Signal routing in telecommunications equipment
- General-purpose electronic module interfaces
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain housing integrity. Check for obsolescence notices as availability may be limited. Validate pin compatibility with mating headers prior to procurement.
Selection Notes
Select this model when a single-row, 12-position female connector is required. The 2.54 mm pitch ensures compatibility with standard PCB spacing. Bottom entry design simplifies wire insertion compared to top-entry variants. Tin plating offers cost-effective performance for non-high-frequency applications. Verify current ratings against system requirements.
Part Context
Part of the M20 series, known for robust mechanical performance and wide availability. Designed for general-purpose electronic assemblies requiring reliable connectivity. Complements male header counterparts within the same product family. Suitable for high-volume manufacturing processes due to standardized dimensions.
Replacement Considerations
M20-7880646 serves as a verified substitute offering identical 12-position specifications with right-angle orientation. Cross-reference pinout configurations to ensure mechanical fit. Validate electrical parameters match original design requirements before substitution.
