M20-7872442

Overview

The M20-7872442 is a socket assembly header from the Harwin M20 series, designed for surface-mount technology. It features a dual-row configuration with 24 positions and a standard 2.54 mm (0.1 inch) pitch. The connector utilizes square contact shapes with gold plating on the mating interface to ensure reliable signal transmission. Constructed with nylon insulation and brass contacts, it supports board-to-board or cable connections. The component is rated for operation between -40°C and 105°C and carries UL94 V-0 flammability classification for safety compliance.
