Overview
The M20-7810445R is a rectangular connector receptacle from the Harwin M20 series, designed for surface mount technology. It features an 8-position configuration with a dual in-line layout (4+4) and a 2.54 mm pitch. The contacts are female sockets with gold plating on the mating interface to ensure reliable signal transmission. This component utilizes a push-pull fastening mechanism for secure board-to-board or cable stacking connections.
Feature Summary
- Dual in-line socket assembly with 8 positions
- Gold-plated contact surfaces for enhanced conductivity
- Push-pull locking system for secure retention
- Surface mount termination for automated PCB assembly
Applications
- Board-to-board interconnections
- Cable-to-board stacking applications
- High-density electronic module interfaces
- Industrial control system connectors
Procurement Notes
Verify the specific suffix 'R' against the official datasheet to confirm reel packaging requirements. Ensure compatibility with standard reflow soldering profiles for surface mount components. Confirm that the gold finish meets the required environmental standards for the intended application environment before finalizing procurement orders.
Selection Notes
Select this model when a low-profile, high-reliability connection is needed for dense circuit layouts. The push-pull feature simplifies mating cycles compared to screw-lock variants. Consider the 2.54 mm pitch constraints and verify that the 8-pin count aligns precisely with the design schematic requirements.
Part Context
This part belongs to the M20 family of connectors, which are engineered for demanding industrial and telecommunications environments. The series emphasizes robust mechanical performance and consistent electrical characteristics across various pin counts and configurations.
Replacement Considerations
Consult the manufacturer's obsolescence notices for direct substitutes. Verify that any alternative maintains the identical 2.54 mm pitch and dual-row geometry to ensure mechanical fit without redesigning the footprint.
FAQ
What is the contact material composition?
The contacts are constructed from phosphor bronze with a gold plating finish.
Does this connector support top entry?
Yes, the receptacle allows for both bottom and top entry mating options.
