M20-9970445

Headers, Male Pins Overview

The Harwin M20-9970445 is a vertical pin header connector from the M20 series, designed for board-to-board and wire-to-board applications. It features an unshrouded design with 8 positions arranged in a single row. The connector utilizes a 2.54 mm pitch and is intended for through-hole soldering termination. Constructed with brass contacts that are gold-plated for reliable signal transmission, the housing is made of black nylon (PA6T) rated UL94 V-0 for flammability. It operates within a temperature range of -40°C to +105°C and supports a current rating of 3A per contact.
