M20-9972146

Headers, Male Pins Overview

The M20-9972146 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 2.54 mm (0.100 inch) pitch and consists of 42 positions arranged in a dual inline configuration (two rows). The connector utilizes brass contacts with tin plating to ensure reliable conductivity. Rated for 3A per contact and 750VAC dielectric voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T), meeting UL94 V-0 flammability standards.
