M20-9952845

Headers, Male Pins Overview

The Harwin M20-9952845 is a dual in-line horizontal pin header from the M20 series, designed for board-to-board or wire-to-board connections. It features 28 positions with a 2.54 mm (0.1 inch) pitch and utilizes gold-plated contacts for high temperature resistance. The connector supports through-hole mounting with solder pin termination. Rated at 3A per contact, it operates within a temperature range of -40°C to +105°C. Constructed with brass contacts and nylon insulation, this component ensures reliable electrical performance in demanding electronic assemblies.
