Frequently Asked Questions
What are the pin count, pitch, and pin length specifications of Harwin M20-9981546?
The M20-9981546 is a 30-position (15+15 dual-in-line) straight through-hole plug with 2.54 mm pitch and 6.1 mm pin length. The brass contacts with tin over nickel finish provide low insertion resistance and are compatible with standard 2.54 mm pitch PCB footprints used across industrial and embedded computing designs.
How does the through-hole mounting of M20-9981546 benefit designs subject to mechanical vibration?
Through-hole mounting of the M20-9981546 creates solder joints anchored through the PCB substrate, providing significantly greater pull-out strength than SMT pads — typically 50 N or more per contact. The 6.1 mm pin length ensures adequate solder fill depth, making it preferable for industrial and automotive-adjacent applications where vibration could crack SMT solder joints.
When should engineers select the tin over nickel contact finish of M20-9981546 instead of a gold-plated alternative?
Tin over nickel is a cost-effective choice for the M20-9981546 in applications with fewer than 50 mating cycles and operating temperatures below 85°C, where gold plating's superior corrosion resistance is unnecessary. For high-cycle or signal-critical applications requiring contact resistance below 10 milliohms, a gold-plated M20 series variant would be a better alternative.
