Frequently Asked Questions
How many positions does the Harwin M80-8410842 have, and what is its contact pitch?
The M80-8410842 is a 42-position board connector with a 0.8mm pitch, enabling dense signal routing in a small PCB footprint of approximately 0.457 x 0.311 inches. This compact format supports both signal and low-current power connections between stacked boards in space-constrained assemblies.
What contact finish does the M80-8410842 use, and how does it affect mating reliability?
The M80-8410842 uses tin (Sn) with a nickel (Ni) barrier as the termination contact finish, providing corrosion resistance and stable contact resistance over thousands of mating cycles. The nickel barrier prevents tin diffusion, maintaining low-resistance connections across the 42 contacts in demanding industrial and commercial applications.
In which applications is the Harwin M80-8410842 a suitable board-to-board connector choice?
This 42-pin plug connector fits modular embedded computing systems, portable diagnostic equipment, and industrial control modules where board-to-board distances of a few millimeters and 0.8mm pitch density are required. Its RoHS-compliant materials make it compatible with EU-market products, and the compact 0.23-inch body depth suits low-profile stack-up designs with limited vertical clearance.
