However, crossover cables hardly play a role in Ethernet connections. On one end, this cable therefore requires an assignment according to T568A and on the other end one according to T568A. One pair of wires is responsible for receiving data and the other for sending data. These cores are then assigned as follows:Īs soon as two devices of the same type communicate with each other, for example between a computer and a computer, a crossover cable is always used. The eight cores of the cable are sorted in the desired assignment using an insertion aid and crimped in the connector housing. However, these are primarily found in telephone connection lines. Other standards such as RJ11 are also used in telecommunications. The RJ45 connectors are used for data transmission in networks. The term “ISDN connector” is also frequently used for the eight-pole modular connectors. They contain 8 contacts and 8 wire positions utilized for signals or power, meaning they allow for 4 twisted wire pairs. In the case of Ethernet connectors, therefore, all eight available contacts in the plug are used. At a most basic level, RJ45 connectors are modular interconnection devices paired with a cable that deliver data communication to various electronic systems. In any case, the designation for a connector concludes with the number of possible contact positions (P, for “Positions”) and the number of contacts actually fitted (C, for “Contacts”). For example, the “W” stands for “wall socket” or the “S” for an single connection. To connect the RJ45 cable to the interface, two wiring systems are usedT568A and T568B. The most common form of twisted-pair connector, it is an eight-position, eight-contact (8P8C) modular plug and jack. In some cases, there is also an addition that refers to mechanical properties. The RJ45 connector is a standard type of physical connector used for networking computers. This is followed by two numbers that specify the type of plug. The categorization follows a certain scheme, which always begins with RJ (=Registered Jack). There are different versions of plugs and sockets in terms of shape and number of contacts. A few years later, they were standardized by the Federal Communications Commission (FCC). If you have ever tried to make a RJ45 cable you’ll know how frustrating it can be and although these connectors are not cheap they will save a load of time in assembly therefore reducing workshop and installation costs.RJ connectors were introduced by Bell Laboratories (USA) in the 1970s. Let’s start with RJ45, perhaps the term most widely used to refer to Ethernet cables today. External Ground: maximum cable OD: 0.280+in.Internal Ground: maximum cable OD: 0.260in. The RJ45 connectors from L-com are the standard interface for connecting a computer to a local area network (LAN).use in Category 3, 5, 5E or 6 compliant data networks.simple one-piece design bars or liners not required.works with solid or stranded wire separate connectors not required, reducing inventory and confusion.EZ to verify wire sequence, reduces scrap. through holes allow wire pairs to be inserted through front of connector for faster terminations.It is an 8-position, 8-contact (8P8C) modular plug and jack. The wires go all the way through the connector and are trimmed off by the all-in-one action of the Crimp / Cutting tool.Īdditional features of the EZ-RJ45 shielded Cat5e/6 connectors include: The standard RJ45 is the most common twisted-pair connector. The brilliance of the connector system is you no longer have to fiddle with trimming the wires back then getting them to fit in the connectors. Reducing the distance between the wire twists and contacts also improves performance. Pulling the connector down over the cable jacket and seating it tightly in the rear of the connector optimises electrical performance of the termination. By using the new EZ-RJ45, it simplifies twisted pair terminations by allowing the wires to be inserted through the connector and out the front, to easily verify the proper wiring order. The EZ-RJ45 Connector from Platinum Tools is designed to work on both Cat5e and Cat6 cables, solid or stranded. It’s been out for a while but I don’t think it’s getting the attention it deserves.
