The difference between a classic connector and its reverse version can often lead to confusion. Therefore, in this article we will go into the origins and differences of these connector types using the example of an SMA connector.
The difference between a classic connector and its reverse version can often lead to confusion. Therefore, in this article we will go into the origins and differences of these connector types using the example of an SMA connector.
An SMA connector (SMA = Sub-Miniature Version A) is primarily used for applications in frequency ranges from 1GHz to 18 / 26.5 GHz (depending on the version). The characteristic impedance is usually 50 Ohm.
An SMA plug has a union nut with a pin as the inner conductor. The SMA socket is equipped with an external thread and metal tube as the inner conductor.
The RP-SMA connector (RP = Reverse Polarity) is externally the same as the SMA connector, but the RP-SMA connector (also called Reverse SMA) has a small metal tube as the inner conductor, whereas the RP-SMA socket has a pin. The inner workings of the connectors are therefore reversed, whereas the housing is the same as the classic design (RP-SMA plug: internal thread; RP-SMA socket: external thread).
Originally, this variant was developed so that no SMA connector could be connected to a stronger antenna, but it has now established itself in several areas. Areas of application for reverse SMA connectors are, for example, antenna connections on WLAN devices, GPS antennas or in the automotive sector.
However reverse connectors are not only available as SMA variants; for example, this type also exists in the field of TNC and BNC connectors.
Since an ordinary connector is not compatible with a reverse connector, simply because of the different design, it is advisable to seek an expert opinion if you are unsure.

What are IP protection types?
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.

Many coaxial cables are designed to withstand high temperatures of up to 200°C without damage. These usually have a dielectric made of PTFE and an outer sheath made of FEB, PFA or PTFE. Cables with a dielectric and sheath made of Kapton are even temperature-resistant up to 250°C.
Please note: If temperature-resistant cables are assembled with the matching connectors and bend protectors, the maximum temperature is always that of the component with the lowest temperature resistance. If the coaxial cable is suitable for temperatures up to 200°C, but the connectors are only suitable for temperatures up to 100°C, the maximum temperature for the entire assembly is 100°C. If the maximum temperature is exceeded, the cable must be assembled properly. If this is exceeded, proper functioning is no longer guaranteed.
Many of our cables have standardised fire properties according to IEC60332-3 or DIN VDE 0472-804. As a rule, the basic requirement for this is that the cables do not contain halogens, whose fire properties would be very unfavourable. When substances such as chlorine or bromine burn, toxic substances are produced and a lot of smoke is emitted, which is why they are banned in many areas of application. Cable sheaths made of PVC contain halogens and are therefore not suitable for these areas. Their advantage, on the other hand, is the cheaper price compared to other materials.
In our range, many halogen-free cables are provided with a manufacturer-specific additive. Examples are LSNH (Low Smoke No Halogen), LSZH (Low Smoke Zero Halogen) or FRNC.

It is not uncommon for a coaxial cable to be exposed to substances that can possibly impair its effect. In this case, it is useful to know the chemical resistance of the material in order to select the right cable for your application in advance. As you can see from the table below, in addition to the sheath material of the cable, the temperature of your application is also crucial. This is due to the fact that the structure of plastics changes at different temperatures. The most common plastics of our cable sheaths are considered here: PVC and PE. You can find more information about the different sheath materials in our online shop, also here.

In the meantime, the general trend of cost development has also reached us. Despite the current situation, however, you can be sure that arnotec GmbH is taking all measures to delay passing on increased costs for purchased parts for as long as possible. Nevertheless, the constantly rising prices for energy, transport and materials present us with a challenge, even though our efforts to date have been sufficient to keep our prices largely constant.
Nevertheless, we reserve the right to renegotiate the sales price with you should our sources of supply increase their prices by more than 5%.
Delivery dates
You may also have noticed that delivery dates can change quickly in the current situation. As we only receive insufficient information from our suppliers, we are unfortunately unable to give reliable information on delivery times until we have the material in stock. As soon as we have received all the required parts, you will receive an order confirmation with a reliable delivery date.
Please also note that deliveries can take longer, especially before Christmas. Therefore, it is better to order with a little more lead time or use the express delivery service from UPS.
However, Arnotec always tries to avoid delays in the delivery of goods. Always contact us directly if you have any problems.
Here’s to continued good cooperation.
