Frequently Asked Questions
How does the 3 mm pitch of the M20-9980945 compare to standard 2.54 mm pitch connectors for board layouts?
The M20-9980945 uses a 3 mm pitch rather than the common 2.54 mm pitch, resulting in slightly larger spacing between the 18 contacts. This spacing provides easier hand soldering and increased mechanical robustness, but requires dedicated PCB footprints with 3 mm center-to-center hole spacing. The connector accommodates a 6.1 mm pin length for standard board thicknesses.
What contact finish does the M20-9980945 use and how does it affect connector reliability?
The M20-9980945 features gold (Au) contact finish with a nickel (Ni) barrier over brass contacts. Gold plating provides excellent conductivity and corrosion resistance, while the nickel barrier prevents gold diffusion into the base brass material. This combination ensures reliable low-resistance connections over thousands of mating cycles in humid or mildly corrosive environments.
Which prototyping or embedded system boards are best matched to the M20-9980945 connector footprint?
The M20-9980945 is well-suited for custom embedded system boards, development platforms, and industrial control PCBs that require an 18-position dual-row through-hole header with 3 mm pitch. Its 9+9 DIL configuration maps directly to standard 0.1-inch dual-row socket connectors when using a 3 mm pitch variant, and the male pin configuration mates with corresponding female IDC or socket connectors.
