Many of you may confused on the types of RJ45 connectors. However, this article will introduce and compare the common models of RJ45 connectors with pictures.

With the development of network cable, the type of RJ45 connectors is changing fast as well. There are plenty models of RJ45 connectors. Commonly, you can divide them from different categories of network cable. Now you also can separate them from a dovetail clip , a load bar, a cable cap. Besides the demand of wire OD and AWG, more details are also considered.

In this article, I will list and introduce some typical types of RJ45 connectors. Then you may find the one you need.

For relatively new kind of cable such as Cat7, the RJ45 connectors are always with a dovetail clip, which can be fixed closely on the cable to provide a secure connection.

Now, I’d like to show you following two kinds of connectors that has the dovetail clip.

SJ650: Nickel Plated Shielded Cat7 /Cat6a Modular Plug

  • Including: Nickel Plated ShieldedRJ45 Cat7 /Cat6a modular plug with dovetail clipLoad Bar
  • Compatibility: Cat7 ,Cat6a solid or stranded conductors, backwards compatible with Cat6, Cat5e
  • Superior Transmission meets Cat6a performance requirements per ANSI/TIA-568-B.2-10 for a Gigabit Ethernet channel compliant network;
  • The Ethernet cable cap compatible with cable OD 7~8mm
  • Secure termination for shielded or outdoor-rated cable with an IP camera or security camera installation
  • Suitable for: 23 to 26 AWG round or flat solid or stranded wire, for wire core OD 1.35~1.45mm, AWG and OD MUST BOTH meet the requirements
  • Superior Construction: STP wire connectors , metal housing , 50 micron gold-plated contacts
  • Robust shield termination and strain relief allow for one-step termination process to suppress alien crosstalk and provide a secure connection
  • Faster speed with less interference
  • DIY RJ45 CABLE: Making custom length Ethernet patch cords with GJ669 rj45 crimping tool /Ethernet crimping tool /modular plug crimping tool

SJ651

As for older but more common category like Cat6, Cat5e or Cat5, there are more choices provided. I pick up 4 products, including SJ653, SJ656, SJ660 and SJ661. For most aspects they are similar, except few points.

SJ653: Nickel Plated Shielded RJ45 Cat6a /Cat6 Modular Plug

  • Including: Nickel Plated ShieldedRJ45 Cat6a /Cat6 Modular plugTransparent Cat6a/Cat6 Ethernet RJ45 Cable Cap Connector Strain Relief BootsLoad Bar

  • Superior Transmission meets Cat6a performance requirements per ANSI/TIA-568-B.2-10 for a Gigabit Ethernet channel compliant network;
  • The Ethernet cable cap compatible with cable OD 7~8mm
  • Secure termination for shielded or outdoor-rated cable with an IP camera or security camera installation
  • Suitable for: 24 to 26 AWG round or flat solid or stranded wire
  • Superior Construction: STP wire connectors , metal housing and 50 micron gold-plated contacts
  • Robust shield termination, and strain relief allow for one-step termination process so as to suppress alien crosstalk and provide a secure connection
  • Faster speed with less interference
  • With Ethernet RJ45 Cable Cap Connector Boots, protect the connector of the cable and prevent dust and water from entering the plugs.

SJ656

  • Including: Cat6/Cat5e modular plug Transparent Cable Cap Connector Strain Relief Boots
  • Compatibility: Cat6, Cat5e cable, not for Cat6a Network Cable
  • Suitable for: wire OD 0.96 ~ 1.02, multi-stranded and single-stranded cables 23 AWG ~ 26AWG. Furthermore, AWG and OD MUST BOTH meet the requirements.
  • Construction :STP 8P8C 50 micron Gold Plating Connectors
  • Limit: Not support UTP
  • Better data transmitting with less interference
  • One-piece design(without Load Bar) for easier operation
  • DIY RJ45 CABLE

SJ660

  • Including: Shielded RJ45 Cat6 Pass Through Modular Plug
  • Compatibility: RJ45 Cat6 cable’s data transmitting capability of up to 1000Mbps (1Gb). So, it can be used for CCTV, Security Cameras, Routers, Switches, Printers, and Servers.
  • Suitable for: wire OD 0.93 ~ 1.04, multi-stranded and single-stranded cables 23 AWG ~ 26AWG. Furthermore, AWG and OD MUST BOTH meet the requirements.
  • Construction: With high performance 3 prong and PASS-THRU DESIGN, terminations are simplified. Because wires are inserted through the connector and out the other side
  • 1-piece plug seats cable jackets tightly for fast crimps and connections.
  • Meet the demands of a fast paced work environment with high-quality crimp plugs. That is to say, you need a connector with shielding function. It can prevent signal loss and electromagnetic EMI/RFI interference and maintains a proper ground connection.

SJ661

  • Transparent gold plated RJ45 Cat6 Pass Through Modular Plug
  • Used for TV, TV box, HUB, PC, Modem, Router, Switch, and ADSL
  • Wire OD 0.93 ~ 1.04, multi-stranded and single-stranded cables 23AWG ~ 26AWG. Besides, AWG and OD MUST BOTH meet the requirements.
  • Next, Transparent gold plated RJ45 plugs allow you to identify wire sequence, eliminating scrap and improper crimps.
  • PASS-THRU DESIGN simplifies terminations as wires are inserted through the connector and out the other side
  • 1-piece plug seats cable jackets tightly for fast crimps and connections.
  • Meet the demands of a fast paced work environment with high-quality crimp plugs.
  • It can shield your network in case to prevent signal loss and electromagnetic EMI/RFI interference and maintains a proper ground connection.  
  • At last, let’s see how to DIY RJ45 CABLE:
