M20-9742442

Headers, Male Pins Overview

The M20-9742442 is a rectangular header connector from the Harwin M20 series, designed for surface-mount or through-hole applications with a right-angle configuration. It features 48 positions arranged in a dual inline layout with a 2.54 mm (0.100 inch) pitch. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the termination pins, housed in black polyamide insulation rated UL94 V-0. It supports a rated current of 3A per contact and a voltage of 250V, operating within a temperature range of -40°C to +105°C.
