M20-7811545R

Overview

The Harwin M20-7811545R is a 30-position receptacle connector from the M20 series, designed for surface mount technology (SMT) installation. It features a 2.54 mm (0.100 inch) pitch and utilizes gold-plated contacts to ensure reliable signal transmission. The component is supplied in reel, cut tape, or MouseReel packaging formats.

Feature Summary

• Surface mount receptacle design for automated PCB assembly
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Standard 2.54 mm pitch for broad compatibility with mating headers

Applications

• Board-to-board interconnections in compact electronic modules
• High-density circuit board assemblies requiring SMT processes
• Industrial control systems utilizing standard pin header interfaces

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official datasheets prior to integration. Ensure procurement channels provide valid traceability for this discontinued or limited-stock item variant.

Selection Notes

Select this part for applications requiring a 30-position SMT socket with gold contacts. Verify that the PCB footprint matches the M20 series 2.54 mm pitch specifications. Consider mechanical retention requirements inherent to surface mount receptacles during design phase.

Part Context

This component belongs to the Harwin M20 series, a widely used line of board-to-board connectors. The M20-7811545R specifically denotes a 30-position right-angle or vertical SMT socket variant within this family, distinguished by its contact plating and mounting style.

Replacement Considerations

M20-7811545 is the non-reel version of the same connector specification.
