M20-9970346

Headers, Male Pins Overview

The Harwin M20-9970346 is a male pin header from the M20 series, designed for board-to-board and wire-to-board connections. It features a 2.54 mm pitch with a 3+3 (6-position) dual in-line configuration. The connector utilizes through-hole solder termination and straight mounting orientation. Rated for 3 A current and 750 VAC dielectric withstand voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon, while contacts are brass with tin plating over a nickel barrier.

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish against project requirements, as datasheet descriptions may vary between tin and gold options for this series. Confirm that the 3A current rating aligns with the thermal management capabilities of the target circuit board layout. Ensure the 750VAC insulation rating meets the safety standards required for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a compact, low-profile interconnect solution is required for high-density PCB layouts. The dual-row format supports higher pin counts within a limited footprint compared to single-row alternatives. Verify compatibility with mating sockets in the M20 series to ensure proper mechanical engagement and electrical continuity.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely adopted standard for industrial and consumer electronics. The series offers various configurations including single and double rows with different pin counts.
