MMCX

Ideal for space-critical applications, the MMCX compact and lightweight connectors provide reliable electronic performance from DC to 6 GHz

MMCX 50 Ohm microminiature compact and lightweight connectors are designed for densely populated electronic packages with size and weight limitations. The mechanical stability is maintained via a snap-on interface that uses no slotting in the outer conductor. Typical applications include wireless/PCS devices, telecommunications, GPS receivers and consumer electronics. For medical MRI applications, non-magnetic versions are available.
