M20-9964045

Headers, Male Pins Overview

The M20-9964045 is a vertical pin header connector from the Harwin M20 series, designed for board-to-board or wire-to-board applications. It features a 2.54 mm (0.100 inch) pitch with 40 positions in a single row configuration. The connector utilizes square male pins made of brass with gold plating on the mating interface, housed in black polyamide insulation rated UL94 V-0. It supports through-hole termination and operates within a temperature range of -40°C to +105°C, carrying a current rating of 3A per contact.

Headers, Male Pins Feature Summary

• Features a robust push-pull locking mechanism for secure mating connections.
• Utilizes gold-plated square brass contacts to ensure reliable signal transmission.
• Constructed with high-temperature resistant polyamide insulation for thermal stability.

Headers, Male Pins Applications

• Industrial control systems requiring durable interconnects
• Consumer electronics assembly
• General-purpose circuit board expansion

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact pin count and orientation. Ensure compatibility with mating sockets regarding stacking height and locking mechanisms. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row, 40-position header is required with a standard 2.54mm pitch. Consider the M20 series if push-pull retention and high reliability are prioritized over simple friction-fit headers. Evaluate available stacking heights to ensure sufficient clearance for adjacent components on the PCB.

Headers, Male Pins Part Context

This part belongs to the M20 series, a family of connectors known for their modular design and high-density capabilities. The series offers various row counts and lengths, allowing engineers to customize connector configurations while maintaining consistent electrical and mechanical performance across different product lines.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical 40-position single-row specifications. Verify that alternative parts maintain the same 2.54mm pitch and push-pull locking style to ensure mechanical interchangeability without redesigning the PCB footprint.
