The main difference between RJ11-6P4C connector and RJ12-6P6C connector
The standards for RJ11 and RJ12 connectors are very closely related in that they both use the same six-slot connector, the only difference between the two is how they are wired and the number of wires being used.
This article mainly introduces the difference between the RJ11-6P4C connector and the RJ12-6P6C connector.
The RJ12 connector is a 6P6C wiring standard, which means there are 6 more wires terminated in the connector, taking up all available slots
The RJ11 connector is a 6P4C wiring standard, only four wires are connected, and the remaining two slots are no longer used
Therefore, you need to pay close attention to the phone cord you are using, as a four-slot phone cord may only fit RJ11 and not RJ12, even if they look the same.
Despite the differences, both cabling standards serve the same purpose, telephone lines typically use a center pair, but there are other applications that use the RJ12 standard, and keyed telephone systems and PBXs can take advantage of the extra two connectors
So RJ12 is not common and only people with experience working with big company telephone systems are familiar with RJ12 wiring, on the other hand RJ11 is relatively very common as it is used in most telephone units and lines of some telephone companies
This even evolved into the connector itself, often referred to as RJ11
The main difference between RJ11 6P4C connector and RJ12 6P6C connector
1. RJ11-6P4C connector and RJ12-6P6C connector wiring use the same six-slot connector
2. RJ11-6P4C connector and RJ12-6P6C connector are only used for wiring
3. The RJ12-6P6C uses all six slots, while the RJ11-6P4C connector uses only four of the six available slots
4. RJ11-6P4C connectors are very common in current homes, while RJ12-6P6C connectors are very rare in some large companies
Premier Cable make a lot of RJ11-6P4C connector and RJ12-6P6C connectors
