Frequently Asked Questions
What are the body dimensions of the M80-8400442 plug connector for PCB layout planning?
The M80-8400442 has a body measuring 0.438 inches in length, 0.204 inches in depth, and 0.138 inches in breadth, allowing engineers to plan accurate PCB keep-out zones and connector clearance when routing traces near the mounting footprint.
How does the polarization feature of M80-8400442 benefit maintenance and field service operations?
The polarized plug design of M80-8400442 physically prevents incorrect orientation during mating, reducing the risk of reverse-polarity damage in field service environments. This keying feature is especially valuable on boards with multiple identical connectors where technicians must reconnect quickly and accurately.
What contact finish does M80-8400442 use, and how does it compare to gold-plated alternatives?
M80-8400442 uses tin-over-nickel contact finish, which provides adequate corrosion resistance and low contact resistance at a lower cost than gold-plated contacts. For moderate mating cycles in industrial environments, tin-over-nickel delivers sufficient durability for up to several hundred insertion cycles without significant performance degradation.
