HARTING introduces M12 connector in IEC 61076

November 13, 2018 --- The M12 is a common circular connector and is known as an interface for data and signals. In order to offer a similarly dimensioned interface for energy-intensive applications, the M12 is now also available in the IEC 61076-2-111 standard K-coding. With four power contacts and a PE it is possible to safely transmit 7kW at 630V and 16 A - a lot of power in the interface. HARTING will present the connector at the "electronica" trade fair (13 to 16 November 2018 in Munich / Hall C2, Booth 548).

Ongoing miniaturisation is having an increasing impact on the supply of voltage to drives as well as on networks. The step towards developing and standardising the K-coding was therefore a logical and necessary one. Voltage supplies for circular connectors have up to now been realised via 7/8 inch solutions. In PROFINET, the M12 L-coding with 0.75kW at 63V and 16A is a firmly established standard. In order to offer the M12 form factor to device manufacturers for voltage supply, HARTING will be supplying the K-coding with 7kW at 630V and 16A from Spring 2019, allowing the integrated transmission of data, signals and power.

With the high voltages, the PCB socket must be protected from flashover on the contact side. To this end, all the hold-downs are separated from each other with an insulator. K-coded cable is available in a crimp version. The connection will be secured with the familiar screw fitting typical of the M12 design. There will also be a new PushPull variant which clicks audibly into place.
