Difference Between RJ12 and RJ45

The RJ12 is a six slot connector. The RJ45 is an eight slot connector. Therefore the difference between the RJ12 and RJ45 is in how they are wired and the number of the wires that are being used. ... This means that there are also 6 wires that are terminated in the connector, occupying all the available slots.

Does RJ12 fit RJ45?

The plugs and jacks are wider than their RJ12 counterparts - 7/16"vs 3/8". An RJ45 male plug won't fit into an RJ12 female jack. But an RJ12 male plug will fit into an RJ45 female jack. A lot of RJ12 female jacks are really RJ45 jacks in disguise!

Is RJ12 Ethernet?

Being mainly a connector for Ethernet cables, this device has a configuration of 8P8C. This indicates that it has 8 positions and 8 connection points. This means that it has the capacity to hold 8 wires at a go. The Rj12 has a configuration pattern of 6P6C, meaning that it has 6 positions and 6 connection points.

Can you use RJ45 for telephone?

Cat5, Cat5e, Cat6 cable is frequently used for wiring telephone jacks. You can send up to 4 telephone lines on one 4 pair cable that terminates at a RJ45 (8P8C) jack. The problem is most phones, even multi-line phones, don't directly plug into an RJ45 jack.

What is RJ12 cable used for?

RJ12 is the most common, being used on flat line cords that connect the base of a telephone to the wall. RJ11 is an older version of RJ12, and they are the same size. The difference is that RJ11 uses four internal wires (called conductors) while RJ12 uses six.

Can I use RJ45 instead of RJ11?

Because of dimensional differences between the two (RJ11 is a 4 or 6-pin and RJ45 an 8-pin connector), it is obvious that an RJ45 plug cannot be used in an RJ11 socket.

Can you convert RJ45 to RJ11?

There is no such thing as a RJ45 to RJ11 converter. Two different types of connectors for two totally different standards of communication. RJ11 is a standardized jack using a 6P2C (6 position 2 contact) modular connector, commonly used for single line telephone systems.

What are the 3 types of connectors?

By Michael Pecht and San Kyeong electrical connectors

Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors.

Why is it called RJ45?

RJ45 is a type of connector commonly used for Ethernet networking. ... The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard. Each RJ45 connector has eight pins, which means an RJ45 cable contains eight separate wires.

Can I plug my ethernet cable into a phone jack?

Can Ethernet cable go into phone jack? Yes, as long as there is a ethernet (probably Cat5) cable directly running from the router to the wall jack (obviously the wall jack must be for ethernet, not phone) you would then be able to plug in a patch cable between the jack and your PC.

Does DSL use RJ11 or RJ45?

It has no RJ11 because it's not meant to be connected directly to a phone line. Putting the ADSL signal through the RJ45 port will not give you internet on it, (and may actually damage the unit). The correct way to use it is as you stated, ADSL modem in Bridge mode.

Is phone cable and Ethernet cable same?

Ethernet and telephone cables look fairly similar and it is not uncommon to get the two mixed up. The key difference between the two is the size of the plastic connectors on the ends of the cable. Telephones use an RJ11/RJ12 connector whereas Ethernet uses RJ45.
