M22-2040805

Headers, Male Pins Overview

The Harwin M22-2040805 is a 16-position, double-row right-angle pin header from the M22 series. It features a 2 mm pitch and utilizes through-hole termination for PCB mounting. The connector system employs 0.5 mm square male pins made of phosphor bronze with gold plating. Rated for 1 A current and 650 VAC voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon compliant with UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Utilizes a 0.5 mm square male pin connection system for reliable board-to-board interfacing.
• Features right-angle orientation with through-hole soldering for secure PCB attachment.
• Constructed with UL 94 V-0 rated black nylon insulation for thermal stability.

Headers, Male Pins Applications

• Board-to-board interconnections in industrial control systems
• Signal routing in automotive electronic modules
• General-purpose connections in consumer electronics hardware

Headers, Male Pins Procurement Notes

Verify the specific part number M22-2040805 against project requirements to ensure compatibility with mating sockets. Confirm that the gold-plated phosphor bronze contacts meet the necessary conductivity and corrosion resistance standards for the intended environment. Check RoHS compliance documentation if required by regional regulations. Ensure the through-hole footprint on the PCB matches the specified 3.5 mm pin length and 2 mm pitch dimensions to guarantee proper mechanical fit and electrical performance.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connection is required for high-density applications. The 2 mm pitch allows for compact board layouts while maintaining adequate spacing. The gold plating offers superior signal integrity compared to tin alternatives, making it suitable for sensitive data lines. Consider the 1 A current rating to ensure the connector can handle the expected load without overheating.

Headers, Male Pins Part Context

This part belongs to the Harwin M22 series, which is designed for space-constrained environments requiring robust connectivity. The series is characterized by its small form factor and high reliability. The M22-2040805 specifically addresses needs for 16-way connections in a double-row configuration, providing a standardized solution for modern electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes include other M22 series headers with identical 2 mm pitch and 16-pin configurations, such as M22-2040807 or M22-2040809, depending on contact finish variations. Verify that any replacement maintains the same right-angle orientation and through-hole termination style to ensure mechanical compatibility.
