Key Features
- Latched retention mechanism prevents accidental connector pull-out under vibration, suitable for industrial, robotic, and automotive wire-to-board applications
- Gold (Au) contact finish over nickel (Ni) barrier on termination side ensures low and stable contact resistance across thousands of mating cycles
- Compact plug body (0.398 in × 0.218 in × 0.156 in) fits space-constrained PCB edges in portable instruments, drones, and embedded control modules
Applications
The M80-8820345 is used in wire-to-board interconnect assemblies for robotics actuator modules, UAV power distribution boards, and industrial sensor nodes where a latched, gold-plated plug connector must resist vibration-induced unmating in a compact package. Its small body profile and RoHS-compliant materials also suit medical device wiring harnesses and portable test equipment where connector reliability over 1000 or more mating cycles is required.

Frequently Asked Questions
What is the body size of the M80-8820345 and how does it fit into compact PCB edge designs?
The M80-8820345 plug body measures 0.398 inch long × 0.218 inch deep × 0.156 inch wide. This compact footprint allows placement on PCB edges as narrow as 5 mm, enabling wire-to-board connections in UAV, robotics, and handheld instrument designs where board perimeter space is limited to less than 10 mm clearance from the enclosure wall.
Why does the M80-8820345 use a gold over nickel contact finish rather than tin plating?
Gold (Au) over nickel (Ni) provides a hard, corrosion-resistant contact surface with contact resistance typically below 10 milliohms even after 500 mating cycles, whereas tin plating forms tin whiskers and oxide films at elevated temperatures that increase resistance over time. The gold finish is specified for applications with low mating forces, high mating cycle counts, or environments where contact fretting from vibration must not degrade signal integrity.
What does the latched feature of M80-8820345 add compared to friction-fit connector plugs?
The latched retention mechanism locks the plug to its mating receptacle with a positive click, requiring deliberate depression of the latch to separate the halves. Friction-fit plugs can disengage under as little as 5 N of axial pull or sustained vibration at frequencies above 20 Hz. The latched design holds secure under typical industrial vibration profiles up to 10 g, preventing intermittent signal loss in motor drive feedback lines and sensor harnesses during operation.
In which high-cycle applications would the gold contacts of M80-8820345 outlast tin alternatives?
Gold-plated contacts maintain stable performance for 1000 or more mating cycles without significant resistance increase, while tin contacts typically degrade within 200 to 500 cycles due to oxide accumulation and fretting wear. The M80-8820345 is therefore preferred in test fixtures, calibration equipment, and field-serviceable industrial modules where connectors are mated and unmated repeatedly by technicians and a consistent sub-10 milliohm contact resistance must be maintained throughout the product's service life.
