Magnetic Attraction: Combining Connectors &


Transformers Continued from page 69


example a switch with M12 connec- tors, a transformer is placed as a sep- arate component on the PCB be- tween the Ethernet chip and every connector. This takes up a significant amount of space. In the case of a 16- port switch, the amount of required space is huge.


In these applications, discrete transformers are designed to fulfill two main functions: galvanic isola- tion and protection of the Ethernet chips, and to contribute to enhanced signal quality.


Building the magnetics into the connector is not an entirely new idea. RJ45 PCB jacks with integrated trans- formers are standard and have been widely established. Ethernet commu- nications technology has lagged behind. In order for designers to meet miniaturization requirements, compo- nents also have to shrink. Discrete transformers located all over the board make this very difficult.


M12 Connector of the Future


HARTING’s new solution com- bines a classic M12 PCB connector and a transformer, wrapping them together in a single component that takes up nearly the same amount of space as a regular M12 connector. This frees up board area significantly. Designers then have more freedom to place other components and to pack the space more densely, making devices smaller and more compact. In addition, the connector sup- ports high-quality signal transfer, since the transformer already con- tains all the relevant components. Besides meeting the general M12 requirements of IEC 61076-2- 101/109 and the Ethernet require- ments of IEEE 802.3, the new M12 connectors have been designed to meet the enhanced shock and vibra- tion standards of IEC 61373. Meeting this standard makes the connectors suitable for use in railway applications.


The company offers the new connectors in a D-coded version for fast Ethernet applications and an X- coded version to accommodate Gigabit transfer rates. All models in straight or angular structures are available with or without PoE/PoE+ (Power over Ethernet) to ensure quality data transmission, as well as to supply energy to small devices, such as switches.


With the new connectors, HARTING is reducing the space needed on the PCB for a high-quality connection. Building the transformer into the connector enables the minia- turization of devices and simplifies board layout routing through a robust surface connection. The com- pany slogan for the new devices labels the connectors with a “hard shell and a clever core” — a big devel- opment that is making things small.

authorized PC or mobile device. Intelligent databases learn the thermal dynamic relationships of each profile and quickly provide oven setup suggestions without even running a profile. Finally, almost all reflow ovens installed in any factory today can be retro- fitted to become a smart oven. Industry 4.0 technologies have matured to the point where they are affordable, and now pro- vide real value to factories of all sizes. Embarking on this new jour- ney may seem overwhelming and full of risk. When focusing on a narrow scope, such as smart oven


technologies, an electronic manufac- turer can move up the learning curve with low risk and low investment. Significant benefits, such as fast ROI and happy customers, come

After upgrading reflow, it is much easier to scale up the rest of production to realize Industry 4.0.


quickly. Perhaps the most important benefit, however, comes from the implementation process itself. Each factory will encounter hurdles and learn what works and what does not. For example, how OT and IT work together for a safe solution. Within a few weeks of implement- ing smart oven technologies, the company is far ahead of the learn- ing curve and is well-positioned to scale up the rest of its processes, realizing Industry 4.0.
