Applications
The Harwin M80-8401742 plug connector is designed for board-to-board interconnection in industrial control panels, embedded computing modules, and power distribution boards where polarized plug connections prevent costly wiring errors during field installation or maintenance. Its tin-over-nickel termination contacts provide reliable solder joints compatible with standard lead-free reflow profiles used in automated PCB assembly for consumer and industrial electronics. The polarized housing is widely used in motor control systems, HVAC controllers, and telecommunications interface cards where multiple similar connectors on the same board must be keyed to prevent incorrect cable harness insertion.

Frequently Asked Questions
How does the polarization feature on M80-8401742 prevent wiring errors in multi-connector PCB assemblies?
The M80-8401742 incorporates a physical polarization key in its 1.462-inch plug housing that constrains the mating socket to a single correct insertion orientation, making it impossible to insert the connector 180° reversed or into an adjacent non-mating socket. This feature is critical in industrial control panels and embedded systems where multiple identical connectors are mounted within 5 mm of each other, as mis-mating any of the signal pins could damage components rated for 5 V logic if accidentally connected to a 12 V power pin.
What soldering process is recommended for the tin-over-nickel contacts on M80-8401742 to achieve reliable solder joints?
The tin (Sn) over nickel (Ni) barrier termination contacts on the M80-8401742 are designed for compatibility with standard lead-free solder alloys such as SAC305, using a reflow peak temperature of 245°C to 260°C per IPC/JEDEC J-STD-020 guidelines. The nickel barrier layer prevents tin whisker growth and copper diffusion at elevated temperatures, ensuring reliable solder joint integrity over the connector's rated service life of greater than 1,000 thermal cycles between -40°C and +85°C.
For industrial automation wiring, how many mating cycles does the M80-8401742 plug connector support before replacement?
The Harwin M80-8401742 plug connector is rated for a minimum of 30 mating cycles under standard operating conditions, which is suitable for field-service applications where the connector is disconnected during annual maintenance intervals over a 30-year equipment service life. For applications requiring more frequent disconnection such as test fixture interfaces or modular reconfigurable systems, Harwin's high-cycle M80 series variants rated for 200 or more insertions with gold-plated contacts would be a more appropriate selection.
How does the M80-8401742 body size compare to equivalent-position connectors from other pitch families for PCB footprint planning?
At 1.462 inches in body length and 0.204 inches in body depth, the M80-8401742 plug connector presents a compact profile suitable for placement along PCB edges in systems with limited board space, with the 0.138-inch body breadth allowing connectors to be placed within standard 4 mm component-keep-out zones from the PCB perimeter. Designers should allocate at least 5 mm of clearance above the connector body height for cable routing when the mating harness uses standard 26 AWG to 22 AWG wire, which requires a minimum bend radius of 6 mm at the connector entry.
