RJ25

RJ25 is a type of connector commonly used in telecommunications and networking. It is a 25-pin modular connector that is part of the RJ series of connectors, which are standardized by the Telecommunications Industry Association (TIA). The RJ25 connector is typically used for connecting telephone lines and is also known as a 25-pin telephone connector. It is a smaller version of the RJ11 connector, which has six pins.

The RJ25 connector is designed to be used with twisted pair wiring, which is a type of wiring that consists of pairs of wires twisted together. This type of wiring is commonly used in telephone and networking applications because it helps to reduce interference and crosstalk. The RJ25 connector is typically used to connect the twisted pair wiring to a telephone or networking device.

The RJ25 connector is a male connector, meaning that it has pins that extend from the connector and are inserted into a corresponding female connector. The female connector is typically a 25-pin jack, which has holes that the pins of the male connector are inserted into. The RJ25 connector is designed to be used with Category 3 (Cat 3) or Category 5 (Cat 5) twisted pair wiring, which are types of wiring that are commonly used in telephone and networking applications.

The RJ25 connector is a legacy connector and is not commonly used in modern telecommunications and networking applications. It has been largely replaced by more modern connectors such as the RJ45 connector, which is a 8-pin modular connector that is commonly used for connecting Ethernet cables. However, the RJ25 connector is still used in some legacy telephone and networking applications.
