M20-7852542

Overview

The M20-7852542 is a socket assembly from the Harwin M20 series, designed for board-to-board connections. It features a dual-in-line configuration with 50 positions arranged in two rows. The connector utilizes a 2.54 mm (0.1 inch) pitch to ensure compatibility with standard spacing requirements. This component is specified as a surface-mount device intended for automated PCB assembly processes.

Feature Summary

Dual-in-line socket assembly design for high-density interconnect applications
Surface-mount termination method compatible with standard SMT manufacturing lines
Gold-plated contacts to provide reliable electrical conductivity and corrosion resistance

Applications

High-density electronic circuit boards requiring robust signal transmission
Industrial control systems utilizing modular connector architectures
Telecommunications equipment interfaces demanding stable connectivity

Procurement Notes

Verify the specific contact plating finish and insulation material grade against current project specifications before procurement. Confirm that the surface-mount footprint matches the target PCB layout exactly. Check for any recent product change notifications or obsolescence alerts from the manufacturer to ensure long-term supply chain stability for the assembly phase.

Selection Notes

Select this component when a high-pin-count, dual-row socket is required for surface-mount technology. Ensure the mating header is compatible with the 2.54 mm pitch and the specific locking mechanism of the M20 series. Validate thermal performance limits against the operating environment to guarantee reliability during soldering and service life.

Part Context

This part belongs to the M20 series by Harwin Inc., which specializes in compact, high-reliability interconnect solutions. The series is widely recognized for its push-pull locking system and diverse range of configurations suitable for demanding industrial and commercial environments. This specific model represents a high-position count variant within that ecosystem.
