Hardware for the Ethernet of the future

Hardware for the Ethernet of the future

The increasing level of digitalisation of industrial plants calls for the further development of existing Ethernet cabling. For sensors and local, modular control units in particular, conventional cabling concepts are no longer able to meet the new demands with regard to space requirements and installation effort.

Weidmüller and partners from the field of electrical connectivity all rely on the innovative Single Pair Ethernet technology when developing new industry standards.

Instead of two or four pairs of wires, Single Pair Ethernet cabling requires just one pair of wires for the transmission of data and power. The simple design and the associated reduction in weight, space requirements and installation costs offer many advantages in an industrial environment. Single Pair Ethernet enables the end-to-end, economical connection of a large number of terminal devices in the Industrial IOT, from sensors in the field to the cloud.

Weidmüller supports connector development of the IEC 63171-2 variant for the IP20 environment and the IEC 63171-5 variant for the IP67 environment, in the AWG 26 to AWG 22 range. The new connector range is freely combinable and supports end-to-end, application-independent transmission, from the workstation through the industrial cabling to the cloud.

  • Twice the port density thanks to the ultra-compact design. Only half the size compared to an RJ45 socket, with a pitch of just 7.62 mm
  • Suitable for industrial deployment thanks to a robust locking mechanism
  • M8 pin and socket variants enable pin-socket exchange at the device as well as free field couplings
  • IP20 and IP67 patch cable and device connectors, supporting Power over Data Line (PoDL)
  • IP20 device plug-in connectors with and without LED
  • Plug-in connectors for simple attachment in the field

Even more flexibility with the 4-chamber variant

Four SPE cabling connections (cable-sharing) can be achieved with the 4-chamber variant. The arrangement of contacts ensures ideal electrical properties. The vertically aligned contact pairs minimise interferences between the individual cables. Residual interferences are reduced by the additional shielded cross. Thanks to this ultra-compact design, four Single Pair Ethernet ports are possible in the installation space normally taken up by one RJ45 plug-in connector.

Standardisation, the key to success

Standardisation, the key to success

When developing new standards, the most important task is to establish a uniform and application-independent plug-in-connector face. Together with other manufacturers Weidmüller supports the currently submitted standardization variants according to IEC 63171-2 for IP20 and IEC 63171-5 for IP67.
