M20-9972046

Headers, Male Pins Overview

The Harwin M20-9972046 is a 20-position, dual-row pin header connector from the M20 series. It features a 2.54 mm (0.100 inch) pitch and is designed for through-hole termination on printed circuit boards. The connector utilizes brass contacts with tin plating to ensure reliable signal transmission. Rated for 3A per contact, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon 6T material, meeting UL94 V-0 flammability standards. This straight, unshrouded design supports board-to-board or wire-to-board applications.

Headers, Male Pins Procurement Notes

Verify the specific pin count and row configuration against the official datasheet before procurement. Confirm that the tin-plated contact finish meets the environmental requirements of the target application. Ensure the through-hole footprint dimensions align with the PCB layout guidelines provided by Harwin. Check for any RoHS compliance documentation if required by project specifications.

Headers, Male Pins Selection Notes

Select this component when a standard 2.54 mm pitch header is required for through-hole assembly. The dual-row format is suitable for applications needing multiple signal lines in a compact vertical space. Consider the 3A current rating and 105°C operating limit to ensure compatibility with the system's electrical and thermal profile. Verify that the unshrouded design does not conflict with adjacent components on the assembly.
