huber suhner wire Connector
Connector: usually it attached on the cable or equipment.
Detachable components (except adapters) for electrical connection of transmission line systems.
1. RF connector: It is a connector used in the radio frequency range.
2. Video: Radio waves with a frequency range of 3HZ∽30MHZ.
3. Radio frequency: radio waves with a frequency range of 3,000HZ∽3000GHZ.
4. High frequency: radio waves with a frequency range of 3MHZ∽30MHZ.
5. Coaxial: The inner conductor has a dielectric support, and the structure can obtain the smallest internal reflection coefficient in the frequency range used in the measurement.
6. Triaxial: A transmission line composed of three layers of concentric conductors with a common axis and insulated from each other.


8, grade : The level of mechanical and electrical precision of radio frequency connectors, especially in terms of specified reflection coefficient.

9. Universal radio frequency connector (level 2): A connector that is manufactured with the widest allowable dimensional deviation (tolerance), but can still guarantee the minimum specified performance and interoperability.
Note: The requirements for reflection coefficient may or may not be specified.

10. High-performance RF connector (level 1): A radio frequency connector that specifies the limit value of the reflection coefficient according to the frequency change. Generally, the specified dimensional tolerances are not stricter than the corresponding level 2 connectors, but when it is necessary to ensure that the RF connector meets the requirements of the reflection coefficient, the manufacturer is responsible for choosing a stricter tolerance.

11. Standard test radio frequency connector (level 0): A specific type of precisely manufactured RF connector used to measure the reflection coefficient of level 1 and level 2 connectors, and the error caused by the measurement results can be ignored.

Note: Standard test RF connectors are usually part of different types of adapters, and the connection between the adapter and the precision connector forms part of the test equipment.

12. RF connector sealing
12.1 Sealed connector: It has connectors that can meet the specified gas, moisture or liquid tightness requirements.
12.2 Barrier sealing: The seal prevents gas, moisture or liquid from entering the connector housing along the axial direction.
12.3 Panel sealing: Prevent gas, moisture or liquid from entering the fixing or the seal between the adapter housing and the panel through the mounting hole.
Note: The seal is usually provided as a separate product.
12.4 Sealing of mating surface: The seal to prevent gas, moisture or liquid from entering the interface of a pair of plug connectors.
12.5 Hermetic sealing: Meet the sealing requirements of test Qk in IEC60068-2-17 "Basic Environmental Test Regulations Part 2: Test-Test Q: Seal".
