Many small partners may still have doubts about reverse polarity connectors.Today, Xiaobian will tell you about the common sense of reverse polarity connectors.
1. The concept of reverse polarity connector:
The reverse polarity coaxial connector is a variation of the standard polarity connector, with the opposite interface polarity to the standard polarity connector. "Reverse polarity" does not refer to the signal polarity of the connector itself, but to the change in the male and female of its center contact.
Reverse-polarity connectors have the same housing as standard-polarity connectors (i.e., the same threads as the plug and receptacle connectors), but the center contact is reversed. That is to say, the center contact of the standard polarity socket connector is the female contact (jack), while the center contact of the reverse polarity socket connector is the male contact (pin); the center contact of the standard plug connector The point is the male contact (pin), while the center contact of the reverse polarity plug connector is the female contact (jack). In reality, we can simply record the reverse polarity of the connector as a female header with a pin and a male header with a hole, which is much more convenient when remembering.
2. Commonly used reverse polarity connector products:
The most commonly used reverse polarity interfaces are RP-SMA, RP-TNC, RP-BNC, etc.
3. Features and applications of commonly used reverse polarity connectors:
RP-SMA is a miniature coaxial connector. Generally, the impedance runs at 50Ω. In the way of threaded connection, it has the characteristics of wide frequency band, excellent performance, high reliability and long life. Because of its superior performance, it has many application scenarios and a large amount of consumption. Common uses include Wi-Fi, Bluetooth, ZigBee connectivity, and GPS and cellular antennas.
The RP-TNC ensures interface stability and reliable electrical performance with a familiar threaded interface, which is available in a variety of configurations, including front-mounted bulkhead receptacles that can be secured inside panels or enclosures, an option for sensitive applications. A design element that adds an extra layer of security to the system. The impedance of RP-TNC is 50Ω, which has the characteristics of wide frequency band, waterproof, tamper-proof and durable. Mostly used for antennas, remote equipment measurement, stand-alone or handheld electronic equipment, etc.
RP-BNC is a snap-on connector, which can be quickly connected and disconnected through a reliable snap-lock. It is convenient and quick to install. In the case of a compact design, less space is required for installation. The impedance is generally 50Ω or 75Ω. The frequency of BNC of large foreign manufacturers can achieve 0-12G, but the current domestic technology can't do it, generally only 0-4G. In addition, it also has the characteristics of small size, light weight and reliable performance. Commonly used in antennas, automobiles, telecommunications, base stations, satellite equipment and other scenarios.
