Frequently Asked Questions
What contact finish does the Harwin M80-8420345 use, and why does it matter for connector reliability?
The Harwin M80-8420345 features gold (Au) plating over a nickel (Ni) barrier on its termination contacts. Gold plating provides excellent corrosion resistance and maintains low contact resistance over thousands of mating cycles, making this connector highly reliable in aerospace, defense, and industrial environments where signal integrity and long service life are critical requirements.
How does the latching mechanism on the M80-8420345 improve performance in vibration-prone applications?
The M80-8420345 includes an integrated latch that locks the plug to its mating receptacle, preventing accidental unmating under mechanical shock and vibration. This feature is essential for avionics, military vehicles, and industrial machinery operating in environments with continuous vibration levels exceeding MIL-STD-810 requirements, where an unlatched connector could cause intermittent signal loss or system failure.
What is the pitch of the Harwin M80-8420345, and how many positions does it provide?
The Harwin M80-8420345 is a 3-position plug connector built on the M80 Datamate series 2 mm pitch platform. The 2 mm pitch spacing allows 3 circuits to be routed in a body measuring approximately 0.398 inches in length, providing a compact yet high-reliability solution for multi-signal connections in space-constrained PCB designs used in defense and aerospace systems.
