M20-7852042

Overview

The M20-7852042 is a dual-in-line (DIL) socket assembly from the Harwin M20 series, designed for board-to-board connections. It features 40 contacts arranged in two rows with a 2.54 mm pitch. The connector utilizes phosphor bronze contacts with gold plating and terminates via nickel-plated tin tails for through-hole mounting. Constructed with a nylon housing, it supports a current rating of 12A and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-entry socket design facilitates flexible circuit board integration
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Nylon housing provides structural stability and electrical insulation

Applications

• High-density electronic assemblies requiring board-to-board interconnects
• Industrial control systems utilizing DIL socket architectures
• Consumer electronics manufacturing involving modular PCB designs

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number M20-7852042 with official Harwin documentation. Ensure compliance with RoHS standards and confirm that the specific contact configuration matches the required 40-pin dual-row layout before finalizing procurement orders.

Selection Notes

Select this component when a 2.54 mm pitch through-hole socket is required for high-current applications up to 12A. The dual-entry feature offers installation flexibility compared to single-entry variants. Consider the operating temperature range and material compatibility with mating connectors during the design phase.

Part Context

This receptacle belongs to the M20 series, a widely used line of connectors known for their reliability in demanding environments. The M20-7852042 specifically addresses needs for robust, high-contact-count interfaces where space efficiency and secure mechanical locking are critical for long-term performance.

Replacement Considerations

Direct substitutes must maintain the 2.54 mm pitch, 40-position count, and dual-row configuration. Verify that alternative sockets support the same 12A current rating and through-hole termination method to ensure mechanical and electrical compatibility.
