M20-7881046

Overview

The Harwin M20-7881046 is a 20-position right-angle receptacle connector from the M20 series, designed for board-to-board or cable-to-board applications. It features a 2.54mm (0.100 inch) pitch with two rows of ten contacts each. The connector utilizes through-hole termination and includes tin-plated contacts. Constructed with a durable housing, it supports reliable interconnection in electronic assemblies requiring vertical mating interfaces.

Feature Summary

Right-angle design facilitates compact vertical stacking in dense PCB layouts
Dual-row configuration provides high contact density within a standard pitch footprint
Through-hole soldering ensures secure mechanical attachment to the circuit board

Applications

Board-to-board interconnections in industrial control systems
Cable-to-board connections for peripheral device integration
High-density electronic assembly mounting

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current availability status, as distribution channels may list obsolete or discontinued variants. Ensure compatibility with mating header specifications regarding pin count, row configuration, and plating type before procurement. Cross-reference datasheets for mechanical dimensions to validate fitment within the target enclosure constraints.

Selection Notes

Select this component when a right-angle female receptacle is required for rigid board-to-board or cable connections. The 2.54mm pitch aligns with standard industry spacing, while the dual-row layout maximizes I/O capacity. Consider the through-hole mounting method for robust mechanical stability compared to surface-mount alternatives in vibration-prone environments.

Part Context

This component belongs to the Harwin M20 series, a family of connectors known for their compact design and reliability in demanding applications. The series offers various configurations including straight and right-angle options, single and double rows, and different termination methods to suit diverse electronic design requirements.
