Ethernet cables are terminated with RJ45 connectors. It is known that there are various RJ45 connectors, among which pass through RJ45 connectors have become very popular these years. So, what do pass through RJ45 connectors look like and why are they so popular? We’ll take a closer look at differences between pass through and non pass-through connectors in this article. Pass Through vs. Non Pass-Through RJ45 and Ethernet are two terms that go hand in hand. Developed by IEEE in the 1980s, the Ethernet standard (IEEE 802.3) defines the rules for configuring an Ethernet network (connections), the number of conductors required for a connection, the expected performance, and a data transmission framework. It remains the most widely used and popular LAN technology around the world due to its ease of use, cost, speed, and broad network protocol support with RJ45 connectors being the standard devices utilized in network set-up. This is important because they need to be sharp enough to cut off the tiny wires so they don't mash out and touch each other.

Non pass-through connectors are standard ones used to terminate Ethernet cables. But if you are network beginners, you may find it a frustrating thing to install non pass-through RJ45 connectors. Different from standard RJ45 connectors, pass through RJ45 connectors allow Ethernet cable wires to pass through and out of the whole body. So, you can easily make sure these wires are aligned and the color sequence is correct before crimping. Compared to traditional RJ45 connectors, pass through connectors have their own pros and cons. Connector Type: Choose the correct type according to your requirements (straight-through, crossover, rollover, or keyed). CUI Devices offers a wide range of RJ45 connectorsfeaturing a variety of options including integrated magnetics, PoE, LED indicators, and more.Cabling used in Ethernet and EtherCAT networks is offered in several different types from Cat5 and Cat6 to now Cat7 and even the new Cat8. Each of the cable standards offer greatly different performance metrics, but all still utilize the same RJ45 connectors. This means that each cable, regardless of the standard, will consist of 8 wires and 4 twisted wire pairs, which matches the RJ45’s 8P8C configuration.

Two: have a good set of small sharp wire cutters handy to cut off the excess wire after you push them through but don't cut off the wires just yet, wait till you have all of them through the connector. Better Connection: Pass through RJ45 connectors have a higher success rate of successful termination and a perfect termination can achieve a more stable and reliable connection.

RJ45 basics

The RJ45 Pass through connector is a great choice for many network installation applications for its ease use and efficiency. By following the step-by-step tutorial, these RJ45 connectors can be easy to install. For example, here is an installation guide for two-piece pass-through RJ45 connectors. Buy more connectors than you need. It is wise to test terminate (crimp) the connectors onto the cable to make sure you can work with them. In addition, if you make a bad crimp then you can simply use any extras. Even the most experienced installers make a bad crimp from time to time. Straight-through connectors: These are the most commonly used type and they connect two devices with a straight connection, such as computers connected to routers or switches. So, armed with those requirements we would need to choose the trueCABLE Cat6/6A Pass-Through RJ45 connector (if you wish to use pass through). Once you have decided on whether the RJ45 connector (also referred to as a plug) should be shielded or not, the next thing is… Research for the right cable & plug

No more load bars means less waste and frustration. The ability to see the conductors come through the front of the plug allows you to verify the correct TIA 568A or 568B color sequence which minimizes bad terminations. Less Durable: The pass through design makes copper wires exposed to oxygen, so the RJ45 connectors are easy to damage. If you are new to this kind of activity, then practice as much as practical. The more terminations you make, the better you will get. Crossover connectors: These are used when connecting two similar devices, such as two computers or two switches. RJ45 connectors that will be interfacing with an Ethernet network have several technical considerations to keep in mind during design. At the board level, the focus is on reducing EMI, preserving electrical signal isolation, and maintaining signal integrity. Without diving too far into the details of circuit design, it is important to pay close attention to the length and position of traces on the board. Physical placement of the connectors on the PCB should also be considered.

Table 1: Ethernet cable category specifications (Image source: CUI Devices) Power over Ethernet (PoE) Do not shop by Category for the best RJ45 connector, as this can be misleading when mixing components from different vendors! “Category” stated on any bag of RJ45 plugs can be misleading when it comes to proper fitment, period. There is little, if any, correlation between the two. Are you, the consumer, being lied to? Not precisely. When a manufacturer (that only makes plugs and not the cable, for example) states a category on their plug it’s because they assume the consumer is not technically savvy enough to choose based upon technical data. This is not only a bit insulting, it is confusing. A properly documented and advertised plug would be listed as “Unshielded RJ45 Plug, 3 prong for solid copper Ethernet cable, fits up to 7.00mm OD and 0.94 to 1.04mm insulated conductors.” So, what did the “XYZ Manufacturer” do? They advertised their plug as “Cat6”, leaving out all the important stuff, and this leaves you guessing. trueCABLE is the exception here since we sell a system. We go the extra mile of testing our components together. So, a trueCABLE CatX unshielded RJ45 plug will fit and function on all of our unshielded CatX Ethernet (we will note exceptions as necessary). We also thoroughly document our connecting hardware so you can make an informed choice if you are not using trueCABLE brand Ethernet cable. Most often, you will be able to identify the type of RJ45 Connector you need by looking at the devices and cables that you are connecting. For example, a straight-through connector is needed if you are connecting two computers. What is the best way to crimp an RJ45 Connector?

The ability to supply DC power over these wire pairs eliminates the need for separate power wiring. With no need for separate electrical cables, outlets, or installation, PoE has grown rapidly thanks to those provided cost savings and flexibility. PoE is also designed to be safe, reliable, and scalable. Yes, you can use twisted pair cables with RJ45 Connectors. This is a popular and cost-effective choice for many networking applications. What if I accidentally plug in the wrong type of RJ45 Connector?
