M20-9974045

Headers, Male Pins Overview

The M20-9974045 is a vertical pin header from the Harwin M20 series, designed for board-to-board or cable connections. It features a 2.54 mm (0.100 inch) pitch with 40 positions arranged in a dual in-line configuration. The connector utilizes brass contacts with gold plating for mating surfaces and square contact shapes. Constructed with polyamide (PA6T) insulation rated UL94 V-0, it supports through-hole solder termination. The unit operates within a temperature range of -40°C to 105°C and carries a current rating of 3A per contact.
