The "secret" of reverse polarity connectors

What is a reverse polarity connector? What is the use of reverse polarity connectors? When do I need to use reverse polarity connectors? If you are troubled by these problems, tossing and turning, sleepless at night, or you just want to learn more about this, then this article can meet your needs. Below, we will take a closer look at the "secret" of the reverse polarity connector.

The reverse polarity coaxial connector is a modification of the standard polarity connector that reverses the polarity of the interface. The term "reverse polarity" refers only to the polarity of the pins and has nothing to do with the signal polarity of the connector.

The shell (socket or plug thread) of the reverse polarity connector is exactly the same as that of the standard polarity connector. The difference is that the center pin of the reverse polarity connector is set in the opposite way. In other words, the reverse polarity socket replaces the female jack of the standard polarity connector with a male pin, and the reverse polarity plug replaces the male pin of the standard polarity connector with a center female jack.

The purpose of the initial development of the reverse polarity connector was to distinguish between professional and commercially available equipment, in order to prevent people from violating federal or international regulations and using high-gain professional antennas for commercial wireless equipment. However, nowadays, like standard polarity connectors, reverse polarity connectors are available everywhere, which adds a choice for people and makes installation easier.

The most commonly used reverse polarity interfaces are RP-SMA and RP-TNC, and their most common uses are Wi-Fi, Bluetooth, ZigBee connections, and GPS and cellular antennas.

When describing reverse-polarity connectors during the ordering process, always use the terms "plug" and "socket" to refer to the main structure of the connector (such as reverse-polarity TNC plugs). Do not use "male" or "female". Statement. The words "male" and "female" should only be used to describe the pins. This helps to avoid confusion during the ordering process.
