MHF® 4L LK Receptacle and Harnesses

I-PEX connectors have patented locking technology for enhanced durability in high-vibration environments

Image of I-PEX MHF® 4L LK Receptacle and HarnessesThe MHF 4L LK connector from I-PEX is a robust evolution of the MHF 4L series designed for secure, high-performance RF connections in environments subject to continuous shock and vibration. This micro-RF coaxial connector features a patented mechanical locking system that ensures a reliable connection, even under the most demanding conditions. With a compact mated height of just 2.00 mm and a frequency range of 12 GHz, the MHF 4L LK is ideal for applications requiring both space efficiency and signal integrity. It mates with the standard MHF 4/4L receptacles, making it a drop-in upgrade for existing designs that require enhanced retention force. The locking mechanism of the MHF 4L LK greatly enhances connection reliability by preventing accidental disconnection. This is a crucial feature for automotive, industrial, and ruggedized IoT applications. As a result, the MHF 4L LK is ideally suited for devices that are exposed to mechanical stress, such as drones, robotics, and mobile communication equipment.
