M20-9761946

Headers, Male Pins Overview

The M20-9761946 is a vertical pin header connector from the Harwin M20 series, designed for through-hole PCB mounting. It features a single row with 38 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes square male pins made of brass with tin plating for reliable mating. The housing is constructed from black nylon (PA6T), rated UL94 V-0 for flammability. It operates within a temperature range of -40°C to +105°C and supports a current rating of 3A per contact. This component is suitable for board-to-board or cable connections.

• Tin-plated brass contacts provide corrosion resistance and conductivity
• Black PA6T nylon insulation offers high thermal stability and flame retardancy

Headers, Male Pins Applications

• Industrial control panel interconnections
• Consumer electronics internal circuit boards
• Automotive electronic module interfaces
• Telecommunications equipment backplanes

Headers, Male Pins Procurement Notes

Verify part authenticity by checking the manufacturer's serial markings and packaging integrity against official Harwin documentation. Confirm that the received components match the specified 38-position count and 2.54mm pitch dimensions. Ensure storage conditions maintain the specified temperature limits to preserve material properties. Cross-reference the RoHS compliance statement with the latest supplier declaration to meet regulatory requirements for your specific region.

Headers, Male Pins Selection Notes

Select this component when a high-density vertical connection is required on a single-sided PCB layout. The 2.54mm pitch is standard for general-purpose interconnects, ensuring compatibility with common mating sockets. Consider the 3A current rating for power distribution lines within the same row. Verify that the board thickness allows for the required solder tail length during wave or selective soldering processes.
