Key Features
- 17-contact single-row layout on 3 mm pitch for compact board-to-board signal routing
- Gold-plated contacts and shell ensure low contact resistance and corrosion resistance over thousands of mating cycles
- Polarised body prevents incorrect mating orientation in high-reliability assemblies
- Through-board vertical mounting provides strong mechanical retention under vibration and shock
Applications
The M80-8401745 is used in defence electronics, aerospace instrumentation, and industrial robotics where board-to-board connectors must withstand vibration, shock, and wide temperature swings. Its 17-contact, 3 mm pitch SIL layout suits daughter card and backplane interconnects in rack-mounted equipment. The gold-plated contacts support low-level signal applications where contact resistance below 20 mΩ is required for reliable data transmission.

Frequently Asked Questions
What contact pitch and row count does the Harwin M80-8401745 use, and how does this affect PCB layout density?
The M80-8401745 uses a single-row (SIL) layout with 17 contacts on a 3 mm pitch, occupying approximately 48 mm of board length. Compared to 2.54 mm pitch connectors, the 3 mm spacing allows slightly larger contact pads that improve solder joint reliability, while still fitting within a compact daughter-card edge area typical of 100 mm × 80 mm Eurocard-format boards.
Why does the gold-plated contact finish on the M80-8401745 matter for low-level signal applications in industrial instruments?
Gold plating on connector contacts maintains a contact resistance typically below 20 mΩ throughout the rated mating cycles, preventing the oxide formation that tin-plated contacts can develop after exposure to industrial contaminants or humidity. For analogue sensor signals in the millivolt range, even a 50 mΩ increase in contact resistance introduces measurable voltage error, making gold-finished contacts like those on the M80-8401745 essential for precision measurement equipment.
In which defence or aerospace designs does the polarised through-board mounting of the M80-8401745 reduce assembly errors?
Defence avionics and satellite sub-assemblies that are hand-assembled under time pressure benefit from the polarised keyway, which physically prevents inserting the mating plug in the wrong orientation — an error that could short 28 V power to a 3.3 V logic rail. The through-board vertical mounting adds a mechanical lock that resists the 50 G shock loads typical in airborne equipment qualification, complementing the gold clip retention of the connector.
