M20-9740942

Headers, Male Pins Overview

The Harwin M20-9740942 is a 40-position, dual-row female PCB header from the M20 series. It features a 2.54 mm pitch and is designed for board-to-board applications. The connector utilizes through-hole termination with straight orientation. Electrical ratings include a current capacity of 12A and an operating temperature range from -40°C to +105°C. The housing is constructed from nylon, while contacts are made of bronze with nickel-tin plating. This component complies with RoHS standards.

Headers, Male Pins Feature Summary

• Dual-beam contact design ensures reliable electrical connections and improved durability.
• Compact form factor accommodates high-density PCB layouts within height constraints.
• Housing material withstands reflow soldering processes compatible with SMT models.

Headers, Male Pins Applications

• Board-to-board interconnections in industrial equipment
• High-density circuit board assemblies
• Electronic systems requiring robust vertical mating

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm pin count, row configuration, and termination style. Ensure the selected variant matches the required current rating and environmental specifications for the target application. Cross-reference the manufacturer part number to avoid confusion with similar single-row or surface-mount alternatives.

Headers, Male Pins Selection Notes

Select this component when a high-current, dual-row solution is required for vertical board stacking. The 12A rating supports significant power distribution needs compared to standard signal headers. Consider the through-hole mounting requirement and ensure PCB drill patterns align with the 2.54 mm grid spacing for proper assembly.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which provides industry-standard connectors for demanding environments. The series offers various configurations including male and female headers in single and double rows. These connectors are engineered for cost-effective reliability while maintaining strict dimensional tolerances for consistent mating performance.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other M20 series female headers with matching 40-pin counts and 2.54 mm pitch. Verify that alternative parts maintain the same 12A current rating and through-hole termination type to ensure functional equivalence in existing designs.
