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…

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.

Lutze cables keeping Eden Project’s quarantined plants under control.

Photography of the Eden Biomes by Tamsyn Williams

At the Eden Project, as well as maintaining all the mechanical plant on site, there is also the need to maintain the living plant displays in the biomes and surrounding areas. This is done mostly by growing new specimens from seed or cuttings, and sometimes buying in new plant material. Every seed/plant which comes to our nursery site is inspected for any unwanted pests or diseases, and depending on perceived risk, may be quarantined. All tropical material is quarantined for several months before it can join the main collections in order to eliminate the chance of a damaging pest outbreak in the biomes.

At the nursery there was initially a 2MW oil fired boiler which heated the main 5000m2 glasshouse, and also the physically remote quarantine houses. In 2009 this was replaced by a fully modulating gas boiler set 0-600kw, controlled by a custom programmed Priva BMS system and heated area reduced to 2000m2. At that time, the quarantine facility was not heated from the main system, but by a very basic local control gas air heater.

In 2013 the basic gas air heater had deteriorated to such an extent in the warm moist conditions, that it was no longer economic to keep it in operation. It was replaced by a sturdy LPG fired cabinet modulating air heater (36-72kw output) and linked to the BMS system.eden 1

Michael Cutler, Horticultural Technical Engineer at Eden Project explains, “In order to control the heater we needed to run control cables all the way back to the control room and pick up the BMS wiring. To ensure the best chance of reliability of operation for this heater, we installed a good quality branded cable – 200metres of Lütze Silflex 12C, 0.75mm2, YY. The 12 cores enable: control of the relays which activate the fan and enable heat output, modulation level 0-20mA, and supply/return duct temperatures, and lock out signal.

We also used 3C, 2.5mm2, CY cable (also obtained from Lütze) to run power from the DB in at the quarantine house door to the heater and control panel.eden 3

The cables were easy to work with, the outer jacket stripped nicely without sticking to the cores, the individual cores was flexible enough to enable forming and wiring into DIN rail terminals, and the core numbers were easily identifiable. On top of that, prices were better than our hitherto existing suppliers, and customer service had been excellent. We would always consider using Lütze cables, where appropriate, for our projects or maintenance activities”.

Two does go into One! New LÜTZE Cables

New LÜTZE SUPERFLEX® cable is compatible with the digital interface HIPERFACE-DSL® by SICK®

New Lutze Superflex CableServo motor technology continues to develop further, with the aim of making the technology more user friendly. A new trend for servo motors is integration of the encoder feedback in the transfer cable. The main advantage here is the connection technology, as the connection can be established with just one cable and one connector per motor. With the separate connecting lead becoming superfluous for data transfer, not only is material saved, but a source of error is also eliminated and the installation effort is decreased. LÜTZE added a new innovation to its range and now offers a special servo cable which is compatible with the digital interface HIPERFACE-DSL® from SICK®. This cable is specially designed as a hybrid servo cable, and consists of three elements: a power supply, a separately shielded motor brake pair and a separately shielded data pair for digital data transfer.

The new LÜTZE SUPERFLEX® PLUS M© PUR HYBRID

SERVO 0.6/1 kV has been designed for consistently moving operation in C-tracks. In order to guarantee trouble-free functional integrity of the motor in moving applications, the elements in the cable must remain in their position during movement. Furthermore, electrical interferences between the power supply and ­the data pair must be ruled out through respective shielding. LÜTZE SUPERFLEX® PLUS M© PUR HYBRID SERVO 0.6/1 kV provides all these characteristics, and therefore represents a reliable solution for the connection of all servomotors with HIPERFACE DSL® technology. LÜTZE also provides this new cable fully assembled.
