Applications
The M80-8420742 is used in industrial control equipment, robotics, and embedded computing systems where secure, vibration-resistant wire-to-board connections are essential. Its latched design prevents accidental unmating in applications subject to mechanical shock or continuous vibration, such as motor drives, servo controllers, and mobile data loggers. The tin-over-nickel contact finish also provides long-term reliability in mildly corrosive environments, making the connector suitable for outdoor instrumentation enclosures and harsh-environment industrial panels.

Frequently Asked Questions
What does the latched design of the M80-8420742 provide in vibration-prone environments?
The M80-8420742 uses a positive latching mechanism that locks the plug to its mating receptacle, preventing disconnection due to vibration, shock, or cable pull forces. In applications such as industrial motor drives or mobile robotics operating under continuous mechanical vibration up to several g-force levels, the latch maintains connection integrity that an unlatched connector cannot guarantee.
What contact finish does the M80-8420742 use and how does it affect long-term reliability?
The M80-8420742 uses tin (Sn) over a nickel (Ni) barrier contact finish. The nickel barrier prevents tin migration to the base metal, while tin provides a solderable and low-resistance mating surface with contact resistance typically below 10 milliohms. This finish maintains stable electrical contact through thousands of mating cycles in mildly corrosive environments without gold plating costs.
What are the body dimensions of the M80-8420742 and how do they influence PCB real-estate usage?
The M80-8420742 plug body measures 0.713 inches in length, 0.242 inches in depth, and 0.156 inches in breadth. These compact dimensions allow the connector to be placed in tight PCB areas adjacent to other components, reducing the board area consumed by wire-to-board interconnects while still providing a mechanically robust latched mating interface.
Is the M80-8420742 RoHS compliant, and what does its lead-free status mean for manufacturing?
Yes, the M80-8420742 carries a lead-free (Pb-free) designation, confirming RoHS compliance. This means the connector can be used in products destined for the EU market and other regions with lead restrictions, and it is compatible with lead-free soldering profiles typically peaking at 260°C, allowing standard SAC305 or similar lead-free solder paste without special process adjustments.
Which Harwin connector series is the M80-8420742 part of, and what mating receptacle does it require?
The M80-8420742 belongs to Harwin's M80 series of board connectors, which uses a 2mm pitch and a robust latching housing. It mates with corresponding M80-series board-mount receptacles from Harwin. The M80 series is designed for applications requiring 2A to 3A per contact ratings in a compact, keyed, latched format suitable for industrial and defense-grade interconnect designs.
