Frequently Asked Questions
What contact finish does M52-5112045 use and how does it affect long-term connector reliability?
M52-5112045 features gold (Au) contact finish on the termination side, which provides excellent corrosion resistance and maintains contact resistance below 20 mΩ over the connector lifetime. Gold plating is especially important in low-level signal applications where even minor oxidation can introduce noise, making this connector appropriate for sensor data lines and analog reference circuits.
How do the physical dimensions of M52-5112045 influence PCB layout in compact embedded designs?
M52-5112045 has a body of 1 inch length, 0.197 inch breadth, and 0.335 inch depth, allowing placement in tight board areas alongside other SMD components without conflicting with standard keep-out zones. Its narrow 0.197 inch breadth is less than 5 mm, making it suitable for high-density module boards in robotics controllers, UAV flight computers, and medical monitoring devices.
In which industrial or ruggedized applications does M52-5112045 outperform standard commercial-grade connectors?
M52-5112045 from the Harwin M52 series is designed for environments with vibration levels up to 20 g and thermal cycling from -55°C to +125°C. These characteristics make it superior to commercial-grade board connectors in avionics data buses, military ground vehicle electronics, and oil and gas downhole sensor modules where mechanical and thermal stress would degrade standard connectors within months.
Is M52-5112045 available with short lead times for prototype and production procurement?
M52-5112045 is an active Harwin product stocked by major global distributors, typically available with lead times of 6 to 12 weeks for large volumes and from stock for quantities under 1000 units. Harwin maintains regional distribution hubs in the Americas, Europe, and Asia-Pacific, reducing logistics risk for programs with 500 to 5000 unit monthly production requirements.
