MHz or Megabits? Understanding the requirements of Industrial Ethernet cables with LUTZE UK.

In today’s industrial automation systems, Ethernet plays a major part. The network relies on data being passed through the system at high rates to underpin the performance of the network.

The digital performance of a network is subject to the active devices within the network, such as switches and controllers. However it is the passive devices such as cable and connectors which can ultimately determine a networks performance.

The frequency performance of a component dictates its performance. Let us take Cat 5 cable as an example. Cat 5 cable is specified for operating frequencies up to 100MHz. However the cable is suitable for 100MBIT applications using two pairs and gigabit applications (1,000MBIT) using a 4 pair cable in association with the correct connector.

It is easy to confuse MHz performance with the MEGABIT.

Class                                                       Frequency                Data Rate Capability
Range                     100Mbit                   1GBIT

Cat 5/5e                     100MHz                   2 Pair                       4 Pair

Cat 6                          350MHz                   ✔                             ✔

Cat 6A                       500MHz                   ✔                             ✔

 

Clearly cables of a higher category (Class) meet all the transmission characteristics of the lower classes, they therefore provide additional performance margin in a given application.

 

 

 

Conductor Size  Stranded Ethernet cable does not have the same performance characteristics as solid conductor. This must be remembered when distance is a factor. Ethernet conductors are typically 26AWG and 24AWG, and it is always best to use the largest size when requiring high data rates over long distance. The Profinet standard saw 22AWG cables being introduced, with this wire size there is significant transmission performance advantage over 26AWG and 24AWG, full 100m segment length can be achieved with stranded or solid cable types. Three types have been defined within the Profinet standard (see table below). Care must be taken to select the correct RJ45 connector when using 22AWG cables as many are not compatible with the increased wire size and the larger o/d of Profinet cables.

 

Power Over Ethernet  Spare conductors in an Ethernet cable can be used to provide power to Ethernet devices. Clearly, wire size is important in the calculation of voltage drop in POE applications, and is important to bear in mind in cable selection.

 

Cable Selection  The industrial environment requires suitable cables which have far more robust constructions than those used in office environments. Materials such as PUR are often used to provide mineral oil resistance, high abrasion resistance and are halogen free.

Ethernet cables are available with solid conductors which are only suitable for static applications.

Stranded conductors typically 7 strand for flexible use.  Highly stranded, typically 19 strands for continuous movement e.g drag chain applications.

Lutze VSD Cables

 

 

Have you ever thought about the effects of using just standard cabling for your VSD applications?

Cables are often an afterthought in the planning process but represents actually a very important component in the whole application.

Variable Frequency Drive applications can cause unique electrical issues that are unlike other standard power transmission in machine applications. There are higher demands on the cable connecting the motor to the drive.  Standard multi-conductor cables rated for 500V will most likely not meet the requirements of VSD applications, and can cause operating malfunctions and early failures.

 

Advantages of Lutze Drive Cables

  • Cable is 10-15% lighter than other products – this helps with cable installation.
  • Smaller bend radius means the cable is easier to route and terminate.
  • Low capacitance of the cable aids compliance with EN 50598 as cable losses are reduced.
  • Low capacitance, concentric earth system and effective shielding allows longer
    cable runs in drive applications.
  • Voltages withstand gives protection against transients produced by VSDs
  • Low screen DC resistance affording protection agianst AC harmonics.

 

So for any of your VSD applications, look no further than Lutze, the cable specialists who can offer you the correct cables for the right applications! For further information please click here…

ILME UK Industrial Plugs and Sockets

ILME UK Industrial Plugs and Sockets cover a wide range of different installation requirements. The plugs and socket-outlets are suitable for fixed or mobile installations. The fixed plugs and socket-outlets may be wall or flush mounted.ilme

Due to the wide range of Ilme enclosures of the FM, FC, TM, QM and BK series (types BC…) the flush-mounting plugs and socket outlets can be assembled rapidly in a group configuration. These construction features enable Ilme plugs and socket outlets to be suitable for use in a lot of demanding applications such as:-

  • Mechanical Industry
  • Shipbuilding
  • Chemical and petrochemica
  • Services sector
  • Building industry
  • Agricultural and livestock breeding sector

When selecting the correct type of plugs and socket-outlets, you must consider the following parameters:-

  • The rated current of the equipment to be power supplied via the plug and socket
  • The rated voltage of the power supply and the type of distribution (single or 3 phase, with or without the neutral conductor)  to determine the number of poles for the hour position.  The 1h (hour position) is available for all those voltages or voltage ranges of >50V and for frequencies not covered by the standards.
  • Fixed or mobile installation to determine the construction type of the plug and socket.  (flush mounting straight or inclined, wall, mobile, mobile angled).
  • The location of the installation to determine the level of protection required, IP44 or IP67.  In some areas the installation standard requires a very low voltage so check that too.

The following types of plug and socket outlets are available:-

  • Wall mounting plugs and socket outlets, low and extra low voltage.
  • Plug and socket outlets and straight flush mounting sockets, low and extra low voltage.
  • Plugs and inclined flush mounting socket outlets, low voltage.

Westermo Release New Industrial Routing Ethernet Switches

Westermo has announced the release of 7 new industrial routing switches signalling a step forward in networking performance at the edge of industrial mission critical networks.westermo

The density of equipment at the network edge has increased as well as needs such as enhanced security and network resilience, hence the need for a new generation of industrial Ethernet switches.

RedFox is a high performance layer 3 industrial Ethernet switch designed for high network traffic applications. Seven new switch configurations are available that can be  customised further with SFP transceivers. Two models, the RFI-207-F4G-T3G and RFI-211-F4G-T7G, offer gigabit connections on all ports. The RFI-219-F4G-T7G offers 19 ports altogether including 7 SFP fibre ports in a robust and compact DIN rail mount industrial housing.

The RedFox is designed for use in heavy duty industrial applications in it’s robust aluminium housing and has been tested both by Westermo and external test houses to meet many EMC, isolation, vi­bration and shock standards, all to the highest levels suitable for heavy industrial environments and rail track side application.

RedFox is powered by the Westermo WeOS network operating system which is now delivered in 70 different models in the Westermo range.  WeOS has been developed by Westermo to allow us to offer cross platform and future proof solutions. WeOS can deliver unique IP security functionality for this class of product, for instance a Multiport DMZ can be constructed by utilising the firewall function available in every port.  Remote secure access to a network can be provided using encrypted VPNs.

As a Layer 3 routing switch the RedFox is capable of delivering enterprise type routing functionality with OSPF, RIP and VRRP as well as process level ring recovery times of around 20ms even at speeds of 1 gbit/sec utilising Westermo’s FRNT protocol.

It has wide power range 19-60VDC on dual power inputs for resilience and requires 30% less power than the previous generation of products, a significant benefit for lifetime running costs. A wide operating temperature range –40 to +70°C (–40 to +158°F) can be achieved with no moving parts or cooling holes in the case.

New – Lutze Electronic Housing

LÜTZE has introduced a new electronic housing – the LCOS, which is an intelligent housing solution that can be individually adapted to the requirements of the control cabinet.LCOS

The LCOS from LÜTZE is an IP20 electronic housing system that can be used for both modular housings or as a stand-alone solution, it can also be expanded into a complete modular I/O system via the toll-free connection of data or energy modules. The LCOS’ electronic housing is based on a device carrier that holds the separate housings or the plug-in function units. The patented four-wire bus allows the field side to be supplied with up to 16A of nominal current per conductor. This facilitates the realisation of three-phase functions with an operating voltage of 500V or also 24V applications with a current load of DC 64A. The LÜTZE electronic housing LCOS has UL-approval and can therefore be used worldwide. The temperature application range lies between -40° C and +85° C. On the basis of the various approvals and fire tests, such as V-0, NFF I2 and NFF F2, the LCOS housing is also suitable for use in rough ambient conditions.

Various models allow individual solutions.

If the LCOS housing system is used in a modular way, plug-in data or power modules with supply options supply power to the system and allow the creation of a data and power bus. The modules are interchangeable so that four results are possible: 2x data; 2x power, 1x power/data, 1x data/power. A further advantage: The connection between the modules does not need to be wired, it is connected via insulated bridges. The LCOS function housing is available in four models: Either as a housing that is 22.5 mm or 35 mm wide, or alternatively with or without side terminals. In combination with the supply the construction width is 57.5 or 70 mm. The LCOS housing is equipped with three standard markers so that a total of 18 characters can be used for labelling purposes. As an additional service, LÜTZE supplies both customised front plates and also individual colours to implement the Corporate Identity of the device manufacturer. Thanks to 64 freely selectable codes, it is impossible to connect the modules incorrectly. They are connected directly to the carrier rail via PE contacts. Regardless of the housing configuration, the LCOS system has 42 connection points. The data bus is equipped for future purposes with 12 data contacts to allow the individual design of the device communication system e.g. the connection of the power modules or bus-capable load monitoring modules.
