An RJ11 connector is typically used for telephone lines and is part of a family of connectors often used in networking and telecommunications. The RJ11 connector generally comes with 4 or 6 pins but can also have a 2-pin configuration.

In the case of an RJ11 2-pin connector, only two of the available positions are used to connect a pair of wires. This 2-pin version is typically used for a basic telephone connection or a simple device that only requires two conductors for communication, such as a landline phone or a modem.

Some key features of an RJ11 2-pin connector:

• Size: It is a small, modular connector, often measuring around 9.6mm wide.
• Pins: The 2-pin version uses just the two central contacts of the connector.
• Wiring: It usually connects to two wires: one for the "tip" and the other for the "ring" of the telephone circuit.
