- Introduction to RJ11 connector
RJ11 connector refers to the connector of the telephone line
The name RJ stands for Registered Jack, which is derived from the USOC (Universal Service Ordering Codes, Universal Service Classification Code) code of the Bell System. It was originally the common name of a connector developed by the American Western ElectricCompany.
- Difference Between RJ11 and RJ45 connectors
1. Different structures
There are only four wires inside the RJ11 connector, and eight wires inside the RJ45 connector. Since more wires must be accommodated, the RJ45 connector is also a little larger than the RG11. The RJ11 crystal head can usually be inserted into the RJ45 connector, but not vice versa, but it is recommended not to RJ11 crystal head for RJ45 connector.
2. Application differences
The biggest difference between RJ45 and RJ11 connectors is where they are used.
● RJ45 connector
Connectors are used in networks, routers, and switches to connect computers or other network elements to each other.
● RJ11 connector
Is used for telephones, ADSL, modems
3. Wiring scheme
● RJ11 connector
The connector has six terminals, usually only the middle four pins are used
● RJ45 connector
It has two different wiring schemes T-568A and T-568B which can be used to create crossover cables or straight-through cables
- JY electronics’RJ11 Connector ESD/EOS Solution
In electronic products, the RJ11 connector is widely used. However, due to the harsh working electromagnetic environment and the fact that the product is often near high-voltage power supplies, the RJ11 connector often experiences overvoltage or overcurrent.
Therefore, reliable circuit protection devices need to be added to the circuit design. In order to meet the above requirements, JY Electronics launched its product TS61089B-H for the RJ11 connector ESD/EOS protection solution.
