Delta's QMA Series

Delta QMA jacks are connectors with size and performance similar to SMA connectors, but with a snap-on interface for quick mating and unmating, and brass body construction for economy. Designed to mate with all QMA plugs, they offer good electrical performance up to 6 GHz.

The PressMount mounting configuration allows QMA receptacles to be mounted securely in a single through hole, with center-to-center spacing as little as .325 inch. Flange-mounted jack receptacles are available as well.

New types are being added to our product line, so please call with your requirements for other QMA configurations.
