M20-7821246

Overview

The Harwin M20-7821246 is a PCB receptacle connector from the M20 series, designed for board-to-board applications. It features 12 contacts arranged in a single row with a 2.54 mm pitch. The connector utilizes through-hole mounting and tin-plated phosphor bronze contacts. Rated for 3A current and 1000V voltage, it employs polyamide insulation material. This component supports general purpose, industrial, and telecommunications environments.

Feature Summary

• Single-row female socket configuration for vertical PCB mounting
• Tin-plated phosphor bronze contacts ensuring reliable electrical connection
• Polyamide insulation housing providing structural stability

Applications

• General purpose electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific contact count and plating finish against official datasheets before procurement. Confirm that the through-hole mounting style aligns with the target PCB design requirements. Ensure the voltage and current ratings meet the operational demands of the intended application circuit to prevent performance issues.

Selection Notes

Select this component when a single-row, vertical board-to-board interface is required. The 2.54 mm pitch ensures compatibility with standard spacing layouts. Consider the tin plating for cost-effective solutions where gold plating is not strictly necessary for corrosion resistance or low impedance needs.

Part Context

This part belongs to the Harwin M20 series, which offers compact industrial standard sockets. The series is engineered to meet PCB density and height constraints while maintaining durability. The M20-7821246 specifically provides a 12-position solution within this robust connector family.

Replacement Considerations
