SnapN


The SnapN connector range is backwards compatible with N connectors. It means that SnapN jacks (f) can be mated with N plugs (m). Compared to the threaded N connectors, the SnapN connectors have a reliable quick-lock mechanism, which prevents an unintentional disengagement by shock, vibration or pulling the cable.

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

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