The Perfect Time to Switch to Single Pair Ethernet.
Single Pair Ethernet is now an established solution, and the high demand seen recently shows it. Weidmuller have the best hardware lineup, waiting to maximise your operation,
so you can count on them!
Single Pair Ethernet has become an unstoppable force, ultimately also due to the increasing industrial use of Ethernet. According to a study by HMS Industrial Networks, in 2016 around 64% of all communication in industry was still based on fieldbuses, with just 30% based on Ethernet. This ratio was almost exactly reversed in 2021, only the 5% share for wireless solutions remained unchanged.
"In the past year we have been approached by many of the large sensor
manufacturers at trade fairs asking about Single Pair Ethernet. Sensors are
becoming increasingly complex, but space remains tight. This makes a system
that can supply a sensor with energy and Ethernet data using a single cable
extremely attractive. We have also received a great deal of feedback from plant
manufacturers from the process and building industry as well as from the factory
and machine construction sectors. All now want to finally use Single Pair Ethernet."
- Simon Seereiner, Head of Product Management IE & SAI at Weidmuller
But this is not the only advantage of the system in the last mile of the plant environment. Normal fieldbuses generally only offer low bandwidths in the kilobit range. A fraction of that supplies by Single Pair Ethernet. Across applications, it impresses with ranges of up to 1000m at 10 Mbit and at shorter distances, it provides transmission properties of up to 1 Gbit/s. At the same time, the potential savings are huge, as Single Pair Ethernet can be used without gateways between machines, controllers and a group-wide IP-based network.
Single Pair Ethernet only differs from the classic Ethernet used in the IT environment at the physical layer. All layers above this, the protocols, transports and application remain unchanged - literally a direct wire from the sensor to the cloud, for which Weidmuller supplies the complete infrastructure. The company is also an active founding member of the Single Pair Ethernet System Alliance, an association of leading technology companies from different sectors and areas of application that are bundling their know-how in the Single Pair Ethernet field to drive this technology forward for the Industrial IoT and all other applications.
Weidmuller offers a complete portfolio of user-assembled plug-in connectors for on-site assembly as well as finished patch cables and all of the device connectivity for all connection tasks in the plant environment in protection classes IP20 and IP67. The connectors currently have the smallest mating face according to IEC 63171 on the market. By the way of comparison: the volume is only 20% of that of an RJ45 socket. The components can be integrated into standardised M8 housing and plug-in connectors, as is used for IO-Link or PROFINET. The system provides full compatibility between IEC 63171-2 )IP20) and IEC 63171-5 (IP67). For instance, an IP20 plug can be used as a service plug for IP67. Switches will be added to the portfolio in the second quatre of 2023. A pure data switch with seven ports and SFP module will be joined by a version with four ports and PoDL (Power over Data Line). This enables a power supply of up to 50 W.
"Single Pair Ethernet will reach market maturity in 2023, and Weidmuller will play an
important role. We have cables, plugs and will soon also have switches. This establishes
us as a developer of technology that will provide clear benefits for the communication
architecture in the factory of the future. To our customers, I can only recommend, start
now because you can be sure that your competition already has. Better an Early Adopter
than letting this development pass you by."
