M20-9990345

Headers, Male Pins Overview

The M20-9990345 is a vertical pin header assembly from the Harwin M20 series, designed for board-to-board or cable connections. It features a 2.54mm (0.100 inch) pitch with three positions in a single row. The connector utilizes brass contacts with gold plating for reliable signal transmission and operates within a temperature range of -40°C to 105°C. Rated at 3A per contact, it employs a push-pull locking mechanism and is constructed from black polyamide (PA6T) insulation rated UL94 V-0. The unit supports through-hole soldering with a 3mm PC tail length.
