HARTING M12 with Magnetics
RJ45 sockets with integrated transformer have long been in existence. However, till now an IP65/67 class circuit board connector with transformer has been sought in vain. With the M12 Magnetics, HARTING is now the sole manufacturer to offer this world-first innovation, and HARTING has the central requirements in mind of the markets and customers in the areas of transportation and automation. The interfaces for Ethernet networks must become smaller and, at the same time, more robust.
Interfaces for Ethernet networks must become smaller and, at the same time, more robust
A solution must be found if there is the prospect of moisture, dust or strong vibrations during operation. M12 Magnetics combines the functions of the connector and the transformer required for Ethernet with no increase in size. This component is installed wherever Ethernet-capable components are connected to networks. It protects the chips in devices by means of galvanic separation and at the same time ensures the decoupling of the ground potential between the cabling and the terminal. Till now, the standard has been to partition the individual components on the board. Consequently, connectors, transformers and PHY chips always sit side-by-side.
Your benefits at a glance:
- Space saving of up to 30%
- Simplification of design and design-in of circuit cards
In addition to dispensing with the transformer, the M12 Magnetics does away with additional components such as capacitors and resistors, with the result that up to 30% space is saved in the circuit board layout compared to the area employing the M12 without transformer. This allows customers to reduce housing size while also enabling them to eliminate additional part numbers. In return, the customer obtains power transfer via POE+ as well as better signal integrity, since connectors and transformers work in a coordinated manner. Also, the design and design-in of circuit cards is simplified. Reduced space requirements and fewer components also make routing conducting paths easier.
