M20-9981546

Headers, Male Pins Overview

The M20-9981546 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a dual-in-line configuration with 30 positions arranged in two rows of 15 pins each. The connector utilizes a 2.54 mm (0.100 inch) pitch and accepts male pin contacts made of brass with tin plating. Rated for 3A per contact, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon (PA6T) with UL94 V-0 flammability rating.
