M20-7831246

Overview

The Harwin M20-7831246 is a dual-in-line receptacle connector from the M20 series, designed for board-to-board or cable applications. It features 24 positions arranged in two rows with a 2.54mm (0.100 inch) mating pitch and row spacing. The connector utilizes female sockets with tin-plated contacts and employs a push-pull fastening mechanism for secure engagement. Designed for through-hole termination via soldering, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon material rated UL94 V-0 for flammability, ensuring reliable performance in electronic assemblies requiring robust interconnect solutions.
