Miniature coaxial high-voltage connectors are also known as MHV connectors. When mated, they have a test voltage of 5 kV rms and an operating voltage of up to 1.6 kV rms. They are also designed for applications up to 300 MHz.
MHV-connectors are based on the construction of BNC connectors, but they have protrusive insulators, what leads to a slight protection against contact of conductors under voltage in an uncoupled condition
For a maximum contact protection of uncoupled connectors, the connector series SHV is recommended.
Our complete MHV range is available via our online shop.
To ensure greater safety, we offer SHV high-voltage connectors (SHV = Safe High Voltage) in addition to MHV. The inner conductor contacts are backspaced in order to exclude the contact of conductors under voltage when unconnected. When connecting, the outer contacts touch each other before the inner contacts.
SHV-Connectors are suitable for all applications up to 5 kV DC or 3.5 eff. These connectors are particularly used for nuclear devices as well as for testing and measuring devices. All given values are valid in connected and disconnected condition
Our complete SHV range is available via our online shop.
Do you need pre-assembled high-voltage cables with MHV or SHV connectors according to your individual specifications? In our online cable configurator, you can assemble your desired cable according to your requirements under the section “High-voltage cables”. Please note that our high-voltage connectors are also compatible with some regular 50 Ohm cables. Simply select the “Coaxial cable 50 Ohm” category.
The abbreviation IP stands for International Protection or also Ingress Protection (protection from intrusion). In our case, the protection class for coaxial connectors provides information about their suitability for certain environmental conditions. This classification clearly clarifies whether a connector is suitable for outdoor use, for example, or whether it could be damaged by penetrating moisture. Incidentally, similar requirements for cables are explained in the article “Jacket materials for coaxial cables”. The individual protection classes are defined within Germany according to DIN and internationally according to ISO.
How is the IP code composed?
The code for the IP protection class always consists of the letters IP and two digits. In the ISO range, a “K” is added to the two highest protection classes in case of increased requirements (e.g. IP69K). In general, there are the protection classes IP00 to IP69 (or IP69K), with the former offering no protection at all and the latter offering maximum protection.
The first digit describes the protection against contact and foreign bodies and the second digit the protection against water. The higher the number, the better the protection against the described influence. This can be easily read in the following two tables, which explain the gradations of the protection classes:
1. Reference number
Protection against touch
Protection against foreign bodies
0
No protection against touch
No protection against foreign bodies
1
Protection against large-area contact with the hand
protection against foreign bodies with ∅ ≥ 50mm
2
Protection against touching with the finger
protection against foreign bodies with ∅ ≥ 12mm
3
Protection against contact with tools or wire
protection against foreign bodies with ∅ ≥ 2,5mm
4
Protection against contact with tools or wire
protection against foreign bodies with ∅ ≥ 1,0mm
5 (5K)
Complete contact protection
protection against dust deposits inside
6 (6K)
Complete contact protection
protection against dust deposits (dust-tight)
2. Reference number
Protection against water
0
no protection
1
Protection against vertically falling dripping water
2
Protection against diagonally falling dripping water up to 15°.
3
Protection against dripping water falling at an angle of up to 60°.
4
Protection against splashing water from all directions
5
Protection against water jets from any direction
6
Protection against strong jets of water
7
Protection against submersion up to 30min
8
Protection against permanent immersion
9
Protection against water during high-pressure cleaning
In our range we have some connectors whose manufacturers have defined an IP protection class for their products. A good example of this are our connectors from Telegärtner, almost all of which are IP classified.
