M40-3010446

Headers, Male Pins Overview

The Harwin M40-3010446 is a single-row, surface-mount pin header featuring a 1.0 mm pitch and four positions. Designed for vertical wire-to-board connections, it utilizes a shrouded tab housing constructed from polyamide (nylon) 9T with natural insulation color. The contacts are tin-plated over nickel-phosphor bronze, supporting a current rating of 1A and a voltage rating defined by the series specifications. Operating temperature ranges from -25°C to 85°C, with UL94 V-0 material flammability rating.
