Frequently Asked Questions
What pitch and position count does the Harwin M80-8420445 offer for board-level interconnects?
The Harwin M80-8420445 is a 4-position single-in-line connector with a 3 mm pitch, providing compact and reliable board-level interconnects. Its right-angle through-hole termination style and latching feature make it suitable for vibration-resistant applications in industrial, medical, and robotic systems.
How does the latching mechanism of the M80-8420445 benefit designs in high-vibration environments?
The M80-8420445 incorporates a positive latching system that mechanically locks the plug to its mating receptacle, preventing accidental disconnection under vibration levels common in industrial automation and mobile robotics. The latch can withstand repeated mating cycles while maintaining secure contact at its 3 mm pitch across all 4 positions.
What contact finish does the M80-8420445 use and why does it matter for connector longevity?
The M80-8420445 uses gold (Au) plating on its termination contacts, which provides excellent corrosion resistance and maintains low contact resistance below 20 milliohms even after extended use. Gold-plated contacts are especially important in high-cycle or harsh-environment applications such as test fixtures, aerospace systems, and medical diagnostic equipment where signal integrity is critical.
