Type and name of network cable crystal head

1、RJ-45

Both ends of each twisted pair are connected to the network card and hub (or switch) by installing RJ-45 connector (commonly known as crystal head).

RJ-45 plug is a plastic connector that can only be inserted along the fixed direction and automatically prevent falling off. This RJ-45 plug must be installed at both ends of the twisted pair to plug into the RJ-45 interface of the network card (NIC), hub or switch for network communication.

2、RJ11

RJ11 interface is very similar to RJ45 interface, but there are only 4 pins (8 for RJ45). In computer system, RJ11 is mainly used to connect modem. RJ-11 is commonly used in telephone lines in daily applications.

3、CAT6A

Cat6a crystal head is divided into non screen integrated type, non screen split type, shielding integrated type, shielding split type, etc.

4、RJ12

Another rj12 is usually also suitable for voice communication. The structure is the same as the first two, but there are six pins (6p6c). At the same time, two kinds of six slot four needle (6p4c) and six slot two needle (6p2c) are derived.
