N

The N threaded interface connectors are suitable for high frequency, low intermodulation and low return loss applications. Several styles within this range are supplied with sealing rings. Therefore, they are suitable for outdoor applications.

This connector range is suitable for the standard ranges of flexible and semi-rigid cables and is also available in panel mount versions.

The characteristic impedance of the N coaxial connectors is 50 ohm.

N coaxial connectors meet the specification of IEC 169-16 and
MIL-C-39012.
