Circular coding

• Typical application: Transmission of signals for sensors and actuators

• Sizes M8 (IEC 61076-2-104) and M12 (IEC 61076-2-101)

• Rated current 1.5 – 7.5 A

• Rated voltage 30 - 250 V

• Number of contacts 3 - 12

The A-coding in 3 – 5 poles is used for the power supply of field devices. The 8 –12 pole A-coding is a typical coding for transmitting signals.

• Typical application: Data transmission for fieldbus systems (PROFIBUS)

• Size M12 (IEC 61076-2-101)

• 2, 4 and 5 poles

The B-coding is used for PROFIBUS transmissions.

• Typical application: Data transmission for Industrial Ethernet networks

• Size M12 (IEC 61076-2-101), M8 (IEC 61076-2-114)

• Data rate 100 Mbit/s

D-coding is used in circular connectors for transmitting data for Industrial Ethernet applications. D-coding is specified for data rates up to 100Mbit/s Fast Ethernet.

• Typical application: Power transmission of small drives

• Size M12 (IEC 61076-2-111)

• Electricity / voltage 12 A / 630 V

• 4 poles + PE

K-coding is one of the codings used for transmitting power. M12 circular connectors in K-coding are typically used for drives up to 7.5 kW. M12 Power is a space-saving solution that can be used to supply power to other devices.

• Typical application: Transmission of high currents and voltages

• Size M12 (IEC 61076-2-111)

• 4 poles + FE

• Rated current up to 16 A / 63 V

The L-coding is used for supplying power to devices. Compared to K-coding, it has a FE contact and is designed for a different voltage range.

• Typical applications: Data & power transmission for EtherCAT P applications

• Size M8 (IEC 61076-2-114)

• 4 poles

• Rated current: 4 A / 60 V

• 100 Mbit/s

The P-coding is used for transmitting data in EtherCAT P protocols. It manages to simultaneously supply data and voltages up to 240 W.

• Typical application: Power connector for smaller devices

• Size M12 (IEC 61076-2-111)

• 3 poles + PE

• Electricity / voltage 12 A / 630 V

The S-coding is preferred for supplying power to smaller devices.

• Typical application: Hybrid transmission of signals and power in one connector

• Size M12 (IEC 61076-2-113)

• 8 poles (Type 4)

  • 4 x power: 6 A, 50 V

  • 4 x data: Kat. 5, 0.5 A, 50 V

Y-coding has a hybrid mating face. It simultaneously supplies devices with both essential lifelines of power and data. The four data contacts enable transmission rates of up to 100 Mbit/s Fast Ethernet. The four power contacts transmit power of up to 300 W. Hybrid connections, such as Y-coding, can simultaneous supply multiple lifelines. This avoids using separate interfaces, saves resources and actively supports the miniaturisation of devices.

• Typical application: Data interface for Industrial Ethernet networks

• Size M12 (IEC 61076-2-109)

• Data rate 1; 2.5; 10 Gbit/s

• 8 poles

X-coding is used for transmitting Industrial Ethernet in demanding environments. With its excellent shielding, this coding enables transmission rates of up to 10 Gbit/s. Data streams are well protected from electromagnetic influences by the robust metal housing.
