QMA

The QMA connector series was developed as a quick mating replacement for the standard SMA connector. With identical internal construction, the connector exhibits the same RF performance characteristics and mechanical durability with the added benefit of a 360º rotating snap-on locking interface. This snap-locking design improves packing density as no torque wrench clearance is necessary. While operating up to 18 GHz, like SMA the QMA connector exhibits best performance up to 6 GHz.

4-Hole Flange, Front Mount

Connector is fed through and mounted from the front. Used to transmit signal from internal circuitry through a panel, using a flange with four holes to accommodate mounting screws or bolts. Best suited for use with thin panels.
