Turn with it with a minimum effort


Wiha Proturn® screwdrivers enable a comfortable work, even in case you need to gain a high torque.

As we know, the “power” (torque) we´re able to reach by a common screwdriver depends mainly from two factors – from a screwdriver handle size and design and – from our own strength :-). Strength of our hand can be changed only by hard training but a screwdriver intended to gain a maximu “power” is available immediately. The Proturn series from compant Wiha is one of suitable series for this purpose. Series Proturn features a robust two-component handle, with parts made of hard plastic and a soft rubber resulting in a very good grip. Quality chrome-plated and through hardened CrVMo steel guarantees long lifetime.Practical opening in a handle enables comfortable and well-arranged hanging on a wall of your workshop.

FUN but REAL: Nanotechnologies already in SOS electronic…


You certainly all know that you cannot trust Wikipedia completely. In our case, it’s not about the lack of credibility but more about incompleteness. It is generally respected that there are more things that belong in the area of nanotechnologies – when something needs to be done from scratch, iPod Nano or Nano-SIM card holder.

With these, there is undoubted trend towards reduction (we heard about Pico-SIMs / but that is more of a pikotechnologies that are not object of our interest as of now).
In conventional applications, size of a SIM is not critical. But in portable devices, every nanometer saved is good. That’s why we offer new Nano-SIM card holders. All are universal – they accept red, green, acorns or bells nano-SIM cards. In higher society hearts, diamonds, clubs and spades are used – these also can be crammed in the holders.

19″ system of enclosures will provide you unexpected space


With plug-in enclosures from Fischer Elektronik, it´s easy to solve placing your device into a 19“ „rack“.

What enclosure to use for your electronic device and how to sort them when there are several ones on one place? That´s the question reaching almost to beginnings of electronics. No wonder, that since those times a lot of solutions were developed, which were so good, that they´re actual even nowadays. One of such examples is also a known modular 19“ system (482,6 mm wide), where various electronic devices are placed into a carrying rack.
This system is highly modular and at a fixed width it enables to use various height of devices. That´s why in a 19“ system can often be found thin (slim) devices only few centimeters high, but also giants with a height of several tens of centimeters.

Company Fischer Elektronik as a well known producer of device enclosures, heatsinks and connectors, produces a wide range of enclosures suitable for the 19“ system, where you certainly can find a type suitable for your application. A good example is the VESA series. VESA is a universal series of robust enclosures with removable top plate (cover). It´s available in width of 1U to 6U, what represents 43,8 – 264 mm.

Available are three various depths – 260, 300 and 360 mm. The enclosure consists of easy-to-assemble aluminium profiles. Guiding slots inside enable easy installation of PCBs and also available are various accessories and modifications like hands, lock and panels with ventilation openings. Into the enclosure, it´s possible to place a mounting plate (MPH) into the enclosure, which creates as if a double deck and also TS CE mounting rail. Drawings and detailed information about this enclosure can be found on page N8 in the Fischer enlosures catalogue.

How to ensure a stabile RS485 communication?


LTM2881 allows RS485 or RS422 communication even in harsh environment.

RS485 is often used as physical layer for industrial buses like ModBus, ProfiBus, InterBus, P-Net, BACnet and Bit-Bus. Bus length depends on data rate and can reach as much as 1000m.

Correct function of RS485 transceiver requires return path between GND of particular transceivers. This path can be created by connecting GND to earth potential (earthing) or by additional wire. In practical RS485 systems, ground potentials vary widely from node to node, often exceeding the tolerable range. This can result in an interruption of communications or destruction of a transceiver. Standard RS485 transceiver LTC485 is fully functional if GND potential difference is within ±7V. If difference exceeds ±14V damage or destruction can occurs.Using of additional wire which connects together all transceivers GND may looks like a good way how to avoid potential differences. But this leads to creation of ground loops that can even worsen situation.

Optimal solution is to use galvanically isolated RS485 transceiver powered from galvanically isolated power supply. In such a way GND of transceiver is fully isolated from earth potential and additional wire can be used to connect all transmitters GND together without creation of dangerous earth loops.

LTM2881 integrates all necessary components for galvanically isolated RS485/RS422 interface including isolated DC/DC converter into one compact part. No external components are required. Isolation is rated to 2500VRMS/1min and 560Vpeak-peak for continuous operation.

How to test a power supply or solar system?


Electronic loads, programmable and with a recovery function are the best choice for dynamic testing simulating real conditions.

Usually you don´t test your power supply and you assume it is working well with your equipment. But what if not? Sometimes your equipment fails without any evident reason and it might be because your power supply is not sufficient for your application. We have a solution which helps you identify the problems with the power supple – electronic load.
With electronic load you can test your power supply or solar system and you can easily program the behavior of your device or even a bigger load. Elektro Automatik offers a wide range of electronic loads, even with energy recovering function.Further information can be found in the electronic loads catalogue (14,5 MB). Upon request, we´re able to provide you with any product from the Electro Automatik catalogue (14,5 MB).

FLIR TG165 for only 299EUR – it is a bargain!


If prices of thermal imaging cameras seem to you to be high, but you´d like to take advantage of a graphic temperature displaying, then the TG165 is the right device for you for only 299EUR and limited time. Do not hesitate, this price is valid only in October!

Now for only 299EUR and limited time. Do not hesitate, this price is valid only in October!  Infrared thermometer or infrared camera? A typical dilemma, which device to choose can be solved very simply – by a purchase of imaging thermometer Flir TG165!
Thermal imaging camera is a great thing for various industrial segments, as we described to you for example in our article „Even hidden faults can be found with FLIR thermal cameras”. Perhaps the only disadvantage of quality thermal cameras are their prices. Especially for a casual usage perhaps majority of us will consider the 1000+ EURO investment for such a device.

The price of this perfect device now dropped to 299EUR!

A good job can be also done by an IR thermometer but by its usage we´re missing a unique feature of visual imaging of a temperature distribution in a given device. In reality perhaps nobody is able to make for example 3600 measurements ( 60x60px) within few seconds and consequently to make an idea how it looks with a temperature in a given device.

  From this point of view – the novelty of company Flir – TG165 is a unique device intended for everyone, who wants to have a visual idea about temperature for an affordable price. TG165 is a combination of a quality IR “point” thermometer (24:1) with an IR camera with a new Flir „LeptonR“ chip.

Without a useless “going around” it can be straightly said, that the imaging functionality of TG165 has a fix-set range and that it´s not possible to exactly determine temperature from a displayed image (except a middle of the image, where it is measured exactly by a central thermometer). However, usually in praxis it doesn´t matter at all, because such imaging is sufficient to discover warmer/ colder places and consequently – it´s possible to focus a center of a measured field on a given “suspected” place.
In result, we get a device, which is in praxis fully usable for a visual inspection of distribution boxes, motors, compressors, PCBs and other for a roughly half price of a usual thermal camera.

Also beneficial is a double (diverging) laser, which visually shows a measured area – independently of a distance from a measured object. Professional construction and a sturdy construction is also underlined by a fact, that the device is designed to withstand a fall from a 2m height.

Detailed information will provide you the TG165 brochure and datasheet TG165.

Have you tried Serial to Ethernet communication?


More than 50 developers tested Wiznet modules during Pizza workshops in Brno, Bratislava and Budapest.

The main topic of Pizzaworkshop was Ethernet communication via Wiznet modules. Developers had a chance to test how fast and simple it is to connect the device to Ethernet and all of this was led by Joachim Wülbeck from Wiznet.Developers also tried working with EVB kits WIZ550S2E, as well as innovative WiZwiki-W7500. There were also answers for many questions about settings, programming, sending and receiving serial data via Ethernet, as well as troubleshooting the proposed applications.

Pictures will tell you more about how it looked like during the workshop… :-)
