M20-9741046

Headers, Male Pins Overview

The Harwin M20-9741046 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 20 contacts arranged in a double row configuration. The connector utilizes a right-angle orientation for through-hole installation, allowing for perpendicular mounting on the PCB. Contacts are made of brass with tin plating to ensure reliable conductivity. The housing is constructed from nylon, providing mechanical stability and insulation. This component supports a rated current of 3A and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Right-angle design facilitates compact vertical stacking and space-efficient PCB layouts.
• Double-row configuration provides high contact density within a standard 2.54 mm pitch footprint.
• Tin-plated brass contacts offer corrosion resistance and stable electrical performance.

Headers, Male Pins Applications

• Interconnecting daughter boards to motherboards in modular electronic systems.
• Wire-to-board connections in industrial control panels and instrumentation.
• General-purpose signal and power distribution in consumer electronics assemblies.

Headers, Male Pins Procurement Notes

Verify the specific part number suffix against official Harwin documentation to confirm the right-angle orientation and contact count. Ensure that the tin plating specification meets the environmental requirements of the target application. Cross-reference the thermal rating and current capacity with system load calculations before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a right-angle connection is required to save vertical space or align connectors perpendicularly. Compare the 20-position double-row layout against single-row alternatives if higher density is needed. Confirm that the through-hole mounting method is compatible with the manufacturing process and PCB thickness constraints of the assembly.
