RJ is the industrial term Registered Jack. It is an interface standard for Ethernet connectors established by the EIA and TIA in the United States.

RJ45 network cable is a type of cable used to connect computers and network equipment. It is composed of three parts: a copper core (cable), a shielding layer (transport), and an outer layer (extension), usually with 8 contacts to transmit signals, commonly known as 8P8C

RJ45 cables can be widely used in different scenarios through customized connectors:

• Hospital: RJ45 8P8C To 4.0mm Electrode Snap Female ECG EKG EMG Cable;
• Data center, servers, and storage devices: USB Type C With Screws To RJ45 Network Card;
• Supermarket cashier system: USB A To RJ45 Coiled Spiral Extension Cable For Symbol Barcode Scanner,ect.

RJ12 telephone cables are mostly used for broadband communication, telephone switches, and other equipment. They generally have 6 contacts to transmit signals (6P6C), and the wire diameter is relatively thick, usually copper core or aluminum core; The wire diameter is generally 15 μ Above m, up to a maximum of 30 μ M; The core wire structure of RJ12 telephone line is usually oxygen free copper， it has high requirements for the quality of the line. Therefore, Goochain Electronic Technology will conduct strict testing on it to ensure its line quality.

The RJ50 connection cable is a cost-effective serial communication cable mainly used for data and telecommunications that require more wires. It has 10 contacts to transmit signals, hence the name 10P10C.

• Mobile communication: can be used for mobile communication, such as using the buttons and camera of the phone to scan barcodes,look ay Goochain this Customized Type C To RJ50 Ethernet Cable,Connect the USB port and the console port directly with one cable only.

• Data transmission: You can use the keyboard and camera of your phone to scan barcodes, or you can send data from your phone to your computer for processing
