FME cables are a practical and versatile cable assembly for environments that require performance with mobility. You can route and use these versatile selection cables and adapters in a range of indoor and outdoor environments thanks to the reliability and durability of this hard wearing miniature connector.
FME to “other” cable assemblies
Coaxial cable types used in FME cable assemblies
FME cables are assembled using a smaller diameter flexible coaxial cable that allows the connector and cable to be naked through tight spaces led by the narrow FME jack. Here are the main cable types used in FME cables:
RG 58 is commonly used in FME cable assemblies. It often has slight variances in physical specs between manufacturers but is a 50-Ohm impedance cable with a diameter of 4.95 millimeters (0.195 inches). Its center conductor is either solid or stranded and the cable has a single layer of tinned copper braided shield. The minimum bend radius of G 58 is 24.89 millimeters (0.98 inches). Low-loss versions of RG 58 have an additional aluminum foil layer that can achieve 90dB shielding effectiveness and a velocity of propagation of 80 percent. Its maximum frequency is 5 GHz.
RG 174 had a diameter of 2.79 millimeters (0.11 inches). It is highly flexible with a bend radius of 9.9 millimeters (0.393 inches) due to its 7-stranded inner conductor and a single shield layer. of shielding. The impedance of RG 174 is 50 Ohms and it has a frequency limit of 1 GHz.
LMR 100 is an extremely low-loss, double-shielded cable that is known for its superior quality, flexibility, and performance. Though it has a diameter of 2.79 millimeters (0.11 inches), equivalent to RG 174, it has lower losses because it is double shielded. LMR 100 has an aluminum foil layer and braided shield.
The impedance of LMR 100 is 63 GHz with shielding effectiveness greater than 90 decibels. It is highly flexible and has a minimum bend radius of 6.4mm (0.25 inches).
LMR 200 is a larger diameter version of LMR 100 that is also low-loss and flexible and suitable for outdoor use. It has an overall diameter of 4.95 millimeters (1.95 inches) with double shielding. LMR 200 also has an expansile foam dielectric to increase its flexibility.
