Description
The FME (For Mobile Equipment) series is a specialized subminiature RF interface specifically designed for applications requiring cable routing through narrow passages. This male (plug) variant is optimized for the 5mm (0.195″) diameter cable class, which includes the flexible RG58, the high-temperature RG142, and the low-loss LMR195/LMR200 series. The FME interface is highly valued in the automotive and telematics industries because its slim profile allows it to be pulled through vehicle conduits and narrow apertures that would otherwise obstruct larger connectors.
Maintaining a consistent 50-Ohm impedance, this connector is vital for ensuring signal integrity in cellular boosters, GPS systems, and VHF/UHF radio communications. It utilizes a high-reliability dual-crimp termination system for both the center pin and the outer ferrule, providing a gas-tight mechanical bond that resists vibration and cable strain—crucial for mobile environments. Manufactured with a plated brass body and premium PTFE (Teflon) insulation, it delivers superior electrical stability and protection against environmental oxidation in outdoor and vehicle-mounted applications.
