M20-7852242

Overview

The M20-7852242 is a 44-position receptacle connector from the Harwin M20 series, designed for through-hole mounting. It features a 2.54 mm (0.1 in) pitch and supports both bottom and top entry configurations. The assembly utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. The housing is constructed from high-temperature material rated UL 94V-0, providing robust thermal stability. This socket assembly is engineered for secure mechanical connections in dense board layouts.

Feature Summary

• Supports dual entry orientation options for flexible PCB routing
• Utilizes gold-plated copper alloy contacts for enhanced conductivity
• Features high-temperature UL 94V-0 rated housing material

Applications

• High-density electronic assemblies requiring reliable interconnects
• Industrial control systems with thermal stress requirements
• Test and measurement equipment interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Harwin documentation. Confirm that the specific variant matches the required entry type and contact configuration. Ensure compliance with RoHS directives if applicable to the target application environment.

Selection Notes

Select this component when a 44-position through-hole socket is required with versatile entry options. The gold plating offers superior corrosion resistance compared to tin variants. Consider the UL 94V-0 rating for applications involving elevated operating temperatures or strict fire safety standards.

Part Context

This receptacle belongs to the M20 series, known for its modular design and high reliability. The 44-position count accommodates complex signal routing needs. As a socket assembly, it pairs with corresponding pin headers to establish board-to-board or cable-to-board connections within electronic systems.

Replacement Considerations

Check for direct substitutes within the M20 series offering identical position counts and entry types. Verify that alternative components maintain the same 2.54 mm pitch and through-hole termination style to ensure mechanical compatibility.
