With a height of only 4.5 mm are new terminal blocks able to connect LED modules and LED panels aesthetically and with a maximal reliability.

There are numerous SMT connectors on the market, which are suitable for usage on LED panels but even in other applications. That´s why it´s a logic question – why just Wago 2060?

Firstly it is because of a sophisticated construction of a terminal block with a globally known and million times proven screwless spring clamp CageClampS. This clamp has an optimum pressure on a wire ideally responding to a wire diameter, i.e. the thicker wire, the bigger pressure. Also thanks to this is the max. allowed current up to 9A (!). Further, it´s possible to install solid and ferruled wires even without tools. By a simple pressing to a terminal block (for example by a screwdriver), it´s possible to insert even fine stranded flexible leads and by similar way also to disengage. Features of a clamp don´t get worse neither after multiple disengaging of a connection and they remain stable even after a long period of operation.

From other positives it´s necessary to mention a “balcony” construction of an input portion, which makes installation of wires easier and faster. Sufficiently big flat area ensures a reliable application on assembly machines (pick-n-place). And finally – an aesthetic curved shape and a white/cream color cause, that connectors are inconspicuous and they don´t disturb on a PCB.

Terminal blocks are available in 1,2 and 3-pole version. You needn´t be in doubt that you missed development and you still don´t know a circuit operating on 1 pole :-) – naturally the single-pole version is intended for connecting of several modules into series. A big plus is also availability of interconnecting both-sided pins enabling easy and aesthetic creation of a row (string) of several modules.

Pin spacing is 4mm and there´s also available a version with 8mm pin spacing with operating voltage of up to 600V. Connector casing is made of an advanced material (glass fibre reinforced PPA) with a very wide range of operating temperatures.

Novelty is also a newer version – Wago 2061 with up to 12A max. current. Detailed information will provide you the Wago 2060 brochure.

2x UT33 – with a manual and also automatic range selection are ideal “reserve” tool for every workplace.

Majority of us already probably has its own favorite multimeter. However, sometimes it happens, that we need to measure two parameters at once (for example voltage and current) and with one device it´s usually not possible… Even though it´s obvious, that it would be ideal to have two multimeters, you didn´t buy it, because you simply don´t want or can´t invest a considerable amount into another tool (maybe even a “top level” one.
That´s why we have for you a tip how to solve this dilemma. It is the multimeter Uni-Trend UT33 and right in two versions:

  • UT33A – automatic range selection, max. count 3999
  • UT33C – manual range selection, max. count 1999

Both tools feature an excellent price/ performance ratio. For the price of approx. 8-11 Euro they offer measurement of all common parameters, incl. AC (voltage, UT33A also current). UT33A also measures hFE of transistors, UT33C a temperature by a K probe. In many cases a higher resolution of UT33A (3999) can be very beneficial. Decent accuracy, solid construction and exchangeable measuring leads (not hard-wired to a device, as usually in this price-level) belong to another pluses of this series. Naturally, multimeters UT33 are also suitable as a “main” tool for beginning amateurs and students.

Further information will provide you the attached pictures and UT33A and UT33C user manuals.

IQRF meets demands of developers and smaller companies and brings possibility to develop wireless applications without programming and with minimum initial costs.

IQRF Alliance and an advantage of usage of Direct Peripheral Access – DPA and hardware profiles were introduced to you in our article IQRF Alliance brings wireless networks without programming. By entering to an IQRF Alliance the user gains access to a full DPA functionality, what greatly simplifies development and usage of IQRF wireless modules. DPA ensures compatibility of all products using this protocol and thanks to this it´s possible to add functionality of wireless communication into your product within few days or weeks.

However if you don´t suppose so fast deployment of your product and a 1000 Euro credit/ year is uselessly too expensive for you, now you have a possibility to use DPA and hardware profiles even without entry into the IQRF Alliance. The only thing you need is to develop with modules marked with „DC“ prefix (data controlled), i.e. for example DCTR-52 … Various IQRF modules are available in two versions – standard, as well as „DC“. If you´re a member of IQRF Alliance, standard modules are the right ones for you (without marking „DC“). If you´re not a member of an IQRF Alliance but despite this you wish to use significant simplification of development in a form of DPA and hardware profiles, then the “DC” modules are ideal for you. For a slightly higher price you have a chance to develop and use wireless communication and control with a maximum simplification. It is beneficial to use “DC” modules up to approx. 400 pcs/year. Then it´s already more advantageous to become a member of IQRF Alliance.

IQRF technology features, description of a new development environment IDE and OS, as well as advantages of IQRF Alliance membership advantages can be seen in a record from our webinar Wireless MESH networks without programming.

Discovering of overheating and joints with a high resistance has never been easier and safer. With the type Flir i3 now moreover price-affordable.

Thermal cameras, i.e. cameras sensitive in infrared range bring a useful information – picture with virtual colors responding to a temperature of a scanned surface. Maybe, at the word “thermal camera” you too get an idea about a well known usage in buildings – inspection of a heat leakage (thermal bridges) = status of a thermal insulation of buildings. But that´s only one of many ways to use these devices. In electronics and power engineering it´s far more interesting for example:

  • searching for faults on a PCB, optimizing of layout in respect to an even heat distribution
  • inspection of distribution boxes with cables, terminal blocks and circuit breakers
  • inspection of motors and transformers
  • inspection of cables interconnections (overheating caused by a high resistance)
  • inspection of cooling efficiency – heatsinks, fans, …
  • inspection of solar panels

…and all this at full operation and under (often high) voltage.

„I have an infrared thermometer, thus I need no camera” – this is a frequent opinion – until the time, you once try working with a camera. The joke is, that one picture from for example camera Flir i3 with resolution of “only” 60×60 pixels equals to 3600 measurements of an IR thermometer. It can be said, that one picture taken by the camera even exceeds 3600 measurements (done by an IR thermometer), because a spatial resolution of the thermal camera is usually better (surface measured by one pixel is smaller) than that of IR thermometers. This way it can happen, that a small source of heat (for example a small overheated component) can´t be discovered by an IR thermometer, while with a camera it will be clearly visible. Naturally, there are many applications where only an IR thermometer is sufficient, but cameras are far better for a professional usage and a maximum work efficiency.

That´s why we decided to incorporate into our offer the world renowned cameras from company FLIR, which is on the edge of development in this segment. As a standard stock item can be found type Flir i3 (3600 px) with resolution of 0.15°C and a viewing angle 12,5°x 12,5°. Big 2,8“ TFT display shows all necessary information and settings. Very advantageous is a possibility to store up to 5000 snapshots into a uSD card (2GB, jpg) and a consequent transfer of files into a PC through a USB. Further detailed information will provide you the Flir i3 datasheet.
Upon order we´re able to supply you any other type from company FLIR in a short leadtime..

With components from Belden, Hirschmann, Lumberg automation and other brands of company Belden group you´ll solve any challenge in industrial automation.

If you work with sensors, signals and a data transfer in industry in general, then you´re probably familiar with brands like Belden, Hirschmann and Lumberg automation. It´s a less known fact, that all these brands (and other) belong to company Belden group.

We mention all this mainly because some components from Belden group could be found in our portfolio already for some time. As an authorized distributor of Belden we enlarged our cooperation even more and enhanced our offer with another products.

In the Belden group portfolio can be found solutions for:

● industrial networking
● industrial connectivity
● cables and cable assemblies
● machine control (MCS – machine control solutions)
● broadcasting and AV, and many other …

From the point of view of producers of various industrial devices are very interesting industrial connectors, i.e. mechanically very stable and reliable connectors with IP rating for transmission of signals from sensors and also in an opposite way – for controlling (driving) of various actuators. It can be said, that they´re „internationally standardized” and widely used , whether in round versions – so called „sensor connectors“(IEC 61076-2-xxx) of various sizes (M8, M12, M20, …) or rectangular – „valve connectors “ according to DIN EN 175 301-803.

Universal connectors usable for power supply, control and data transmission are another very interesting group of components. Here belong for example CA series connectors.

In many cases it´s more convenient and simpler to use ready-made cables with a connector, often hermetically sealed, providing the highest protection against harsh environment and pollution. Cables are available with a PVC or PUR insulation, and also a welding sparks resistant PUR. Cables are available with one connector (the other end is free, suitable for soldering in or insertion into a connector) and also with connectors on both sided (the same or different types). Also available are cables with an approval for usage in a food industry.

For all cases, when several connectors should be interconnected on one place, are suitable so called distribution boxes (I/O modules) with a various count of connectors (ports).

Another interesting group are components for „Industrial Ethernet“. Here can be found for example Ethernet switch, RJ45/M12 adapters and various interconnecting cables.

In respect to a huge amount of versions and series, we recommend you to have a look at the „Belden Industrial Connecting solutions” catalogue, where you can find particular products comprehensively sorted by given groups. Solutions for other segments can be found on http://www.beldensolutions.com website.

Modified connector Euroclamp SHM-F is simply more robust. Thanks to this change, it provides a higher reliability and more space for labeling of signals.

Usually, a miniaturization is a trend almost everywhere where we look. However it´s suitable to miniaturize some things/ components only until some level. This trend is very obvious for example in mobile phones, when many of us disappointed by a „micro-miniature“ keyboard rather bought something bigger. Also nowadays smartphones with a touch display are considerably big, as a size of display brings advantages in this case.

Similar situation is also at new cable connectors (terminal blocks) Euroclamp SHM-F. It is an innovated version of the SHM series. Both are screwless, intended for connection with SV or PV series connectors, which we introduced to you in our article -„Do you already have solved a connection to a PCB?“.

Comparison of both versions is best illustrated on the attached pictures – the original version is on the left side and on the right side is the new version. The main fifference is in the thickness of the connector body, which provides bigger robustness ad a sufficient space for signal marking. Also a positon of a release knob of a screwless clamp is “on the opposite side” in comparison to original version, what should provide a more convenient position of wires to a PCB.

Terminal blocks are declared for 160V/8A and a max. wire cross-section is 1.5 mm2. Screwless construction enables a fast connection and eventua exchange of conductors. New version SHM-F replaces type SHM (only available till stock sell-out).
