M20-7832642

Overview

The Harwin M20-7832642 is a 52-position (26+26) dual in-line vertical female socket assembly from the M20 series. It features a 2.54 mm (0.100 inch) row spacing and utilizes through-hole termination for secure board mounting. The connector supports a voltage rating of 1000V and employs gold plating on contacts to ensure reliable signal transmission. Designed as a receptacle, it facilitates board-to-board or cable connections within electronic assemblies requiring high-density interconnects.

Feature Summary

• Dual in-line configuration with 26 positions per row for high-density connectivity
• Vertical orientation designed for standard through-hole PCB mounting
• Gold contact plating provides durable and low-resistance electrical interfaces
• High voltage insulation rating suitable for demanding power applications

Applications

• High-density board-to-board interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Automotive electronics modules

Procurement Notes

Verify the specific gold plating thickness and material composition against the official datasheet before integration. Confirm that the vertical height and footprint align with the target PCB design constraints. Ensure compliance with RoHS directives if required by the final product specifications. Cross-reference the pin count to avoid mating errors with incompatible headers.

Selection Notes

Select this component when a robust, high-voltage female socket is required for vertical through-hole assembly. The 2.54mm pitch offers compatibility with standard header systems. Consider the mechanical stability provided by the dual-row layout for heavy cabling loads. Evaluate the gold finish requirements against environmental exposure conditions to ensure long-term reliability.

Part Context

This part belongs to the Harwin M20 series, known for its versatility in mixed-signal and power applications. The M20 family includes various header and socket configurations with different pitches and orientations. This specific model represents a high-count vertical socket option, distinct from the lower-count or surface-mount variants available in the same product line.

Replacement Considerations

M20-7832642 is currently listed as an obsolete or end-of-life product. Engineers should consult the manufacturer's obsolescence notification for direct replacements. Alternative solutions may include newer series connectors with similar form factors or updated pin counts. Verify mechanical compatibility before substituting with generic equivalents.
