M20-7811245R

Overview

The M20-7811245R is a surface-mount PCB receptacle from the Harwin M20 series, designed for board-to-board interconnection. It features a 2-row configuration with 24 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes gold-plated contacts to ensure reliable signal transmission in high-density applications. This component supports both bottom and top entry cable connections, offering flexibility in assembly orientation. It is supplied in tape and reel packaging for automated manufacturing processes.

Feature Summary

• Supports dual-entry cable routing options for flexible system integration
• Gold-plated contact surfaces provide enhanced corrosion resistance and conductivity
• Surface-mount design enables efficient placement on printed circuit boards

Applications

• High-density board-to-board interconnections
• Automated surface-mount assembly lines
• Telecommunications equipment internal wiring

Procurement Notes

Verify that the specific suffix 'R' corresponds to the tape and reel packaging format required for your automated pick-and-place equipment. Confirm that the gold plating specification matches your environmental durability requirements. Ensure the 24-position count aligns with your schematic design before finalizing orders.

Selection Notes

Select this model when a low-profile surface-mount solution is required for 2.54 mm pitch applications. Consider the dual-entry capability if space constraints dictate cable routing from either side of the board. Verify compatibility with mating headers within the same M20 series family to ensure proper mechanical engagement.

Part Context

This component belongs to the M20 series, which offers a range of rectangular connectors for various mounting styles. The M20-7811245R specifically addresses the need for surface-mount receptacles with robust contact materials. It complements other variants in the series that may offer through-hole or IDC options.

Replacement Considerations

Direct substitutes within the M20 series include M20-7811245 without the reel suffix, though packaging will differ. Other Harwin M20 series receptacles with matching pin counts and pitch can serve as functional alternatives if mechanical footprint compatibility is verified.
