HARTING ix Industrial® - RJ45 Ethernet Interface

The HARTING ix Industrial® is our answer to the future challenges posed by Industry 4.0 and the IoT.

The HARTING ix Industrial® is our answer to the future challenges posed by Industry 4.0 and the IoT.

The RJ45 connector has been the standard Ethernet interface in IP20 environments for many years.  However, as the demand for smaller devices and sensors increases, the RJ45’s size limits the potential for miniaturization. This is why HARTING developed the ix Industrial® mini RJ45 Ethernet connector, which is a smaller and more rugged connector than the standard RJ45.  It also offers Cat. 6A performance for 1/10Gbit/s Ethernet at the control Level.

The socket size of the ix Industrial® is 70% smaller than the standard RJ45 and enables device manufacturers to use the ix Industrial® in much smaller devices. Making it a "mini RJ45." For device integration, a small yet robust socket with five THR shielding contacts is available for maximum stability on the PCB. The ix Industrial® features stable latching through the use of two metal hooks, and together with the new socket ensures an absolutely secure and vibration-proof connection from the cable to the circuit board -- for a minimum 5,000 mating cycles. 

In regards to device wiring, users can take advantage of flexible, thin system cables with a tight bending radius.  The ix Industrial® can be assembled with the mating face on both ends or mixed, i.e. with the ix Industrial® and the RJ45 connector on opposite ends. This enables a gradual adaptation of individual elements in the control level without the need to directly revise all systems. 

The HARTING ix Industrial® interface is also standardized in accordance with IEC/PAS 61076-3-124.

Captain ix  

The world of industrial production is faced with major upheaval. New problems and risks – but also challenges and great opportunities – must be managed and utilized. In uncertain times, we need orientation points and role models. Sometimes even little heroes. HARTING's Captain ix is a pioneer and a symbolic figure for a new generation of Ethernet interfaces and for a cooperation establishing the new ix Industrial® connector as a new global standard.

Future-Proof with Cat. 6A Performance


Cat. 6A performance means the ix Industrial® mating face is engineered future-proof for 1/10 Gbit/s Ethernet, while its high current-carrying capacity enables current and future PoE applications. This interface consequently combines data transmission and power supply in a single interface, thereby additionally reducing the installation space required for termination technology in your applications.


Working in tandem with its technology partner Hirose, HARTING has developed the little giant and standardized the ix Industrial® mating face according to IEC 61076-3-124. This standardization gives users investment security and, thanks to a broad technological basis, consistently offers them the right contact point for future applications in the IoT (Internet of Things).

Maximum Robustness for Harsh Applications

For Harsh Applications  

The active locking of the socket and connector is achieved using two stable snap-in hooks made of metal, providing clear haptic feedback which confirms a secure connection. The connection between cable sheath and plug connection is engineered in the form of a robust crimp connection. This ensures a perfect and robust interface that even meets the high shock and vibration resistance established in EN 50155 railway specifications, guaranteeing a long service life that boasts 5,000 mating cycles.

Smaller Space Requirements   

The ix Industrial® interface boasts 70 % less installation space compared to typical RJ45 sockets and makes it possible to significantly reduce the size of the full spectrum of device types.
