What do you need to know about the RJ45 connector?
Introduction to RJ45 RJ45 is a type of connector, mainly used for Ethernet networking including connection with PC network cards, data switches, WiFi access points, and routers. It is connected to each end of Ethernet cables and acts as the main source for transferring data.
What’s the difference between RJ45 and CAT5 ethernet cables?
In simple words, connectors at the end of ethernet cables are known as RJ45 connectors which also indicate how the cables are wired, while ethernet cables are termed as CAT5 (also RJ cables) which show the maximum speed the cable can attain. RJ connector comes with eight pins which indicate it can house eight wires inside.
Where does the PHY connect to the RJ-45?
The output from the PHY (whether integrated in the processor, from a controller IC, or from a standalone expansion PHY) connects to an RJ-45 connector. These connectors require a specific termination scheme (see below) to preserve signal integrity.
What’s the difference between RJ connectors and RJ ports?
In serial and ISDN protocols, all pins take part in the communication and are wired in a straight through configuration. Don’t get confused between RJ connectors and RJ ports. Both are the part of RJ protocol where connectors serve as a (male) connector and port that receives the connector is known as (female) port.
What is the data transmission speed of the RJ45 jack?
This allows data packets to be easily driven over a copper line at ranges from 125 MHz all the way up to 20.0GHz. The RJ45 jack has played a critical role in data transfer, from an integrated circuit (IC) all the way through to the receiver end.
How big is a Harting RJ45 ethernet cable?
Our system cables also feature Power over Ethernet (PoE: up to 15.4 W according to IEEE802.3af and bus 25.5 W according to IEEE802.3at) in order to simultaneously supply devices with power. Our HARTING RJ45 Ethernet system cables are designed, tested and additionally certified for industrial and industry-related applications.
