Illuminated push-buttons represent a universal solution into every environment.
An answer to a question, whether it´s nicer to use a push-button with a backlight or not is perhaps a fully subjective matter. However besides an aesthetic point of view we know about at least two main reasons to use an illuminated push-button: easier orientation/ operation in a dark environment and an indication of a push-button status (activation of a given function).
So if we´ll decide for an illuminated push-button, it´s certainly beneficial to have a possibility to choose from a wide range of types and caps. In our offer can be found the best from this segment – components from a Danish MEC with over 70 years experience in production of push-buttons and switches.
Basic production portfolio of MEC switches can be divided into series „3“, „4“ and „5“. Seriesa „5“ i.e. for example 5G or 5E is the newest and the most perspective series, but also the “2” or “4” series are still popular. Types like 4FTH922 or 5GTH9358222 (4ATH98222) represent a ready-made solution with an LED. It´s also worth to mention a universal type 3FTL6, This type has besides a reliability, pleasant actuation and a crisp sound at switching yet one positive fature – it can be equipped with any 3mm LED. All that is necessary is to form leads into a required shape and apply a suitable cap. Perhaps the biggest advantage of this solution is a possibility to use a whatever LED according to your choice and this way to make a customized push-button (especially in smaller production batches). Naturally, at bigger production batches it´s possible to agree with a producer a production of various customized versions.
The most suitable type for your application can be easily chosen in the MEC catalogue (11MB).

With today’s circuit components in ever–shrinking packages, finding an overheating component or a component damaged from heat during assembly can be a challenge. To help isolate those components, Fluke has introduced the TiX series of high-definition thermal imaging cameras.
Consisting of the models, the TiX series cameras have resolutions of 1024×768 and 640×480 pixels that display across the imager’s 5.6-in. display. That’s 3.1 million pixels and 1.2 million pixels, respectively, when using SuperResolution mode. The TiX imagers have a temperature range of -40°C to 2000°C (-40°F to 3632°F).

Innovative flux and a high qualty alloy provide to Stannol Kristall 511 solder wire excellent processing properties with a minimum of clean transprarent residues.
You, who are at production of electronic devices, know, how important is a choice of a suitable solder. A designer of a given device might not focus on a solder used at soldering of the first protoype, bu tin a production it will manifest itself – sooner or later. Not that some solder would be miraculous and otherone unusable, but each one is suitable for something else.
Similarly lie in other segments, even here are some exceptions, when by using the newest materials and know-how from development of solders exist types suitable for multiple applications. One of them is solder Kristall511 Ecoloy with an innovative flux based on synthetic resins. The result is a small spatter and clean, transparent residues, which don´t influence electrical properties of a PCB, i.e. they belong to a “No clean” category – they can stay on a PCB withot cleaning. Kristall 511 is a considerably active solder and it shows its strength even at surfaces with not that optimal solderability and also there, where it´s necessary to solder quickly (for example components that are exceptionally sensitive to temperature). KRISTALL 511 was developed for automated soldering of SMT components, as well as for hand soldering and rework.
This way Stannol, as a producer with rich experience in development of solders (from 1920), produced a combinatio of an alloy+flux with properties meeting majority of requirements of production:
- small amount of transparent residues
- excellent spreading even at poorly solderable sorfaces (copper, brass, nickel,…)
- highly active
- electrically safe residues
- low spitting
- mild odour and small amount of fumes
On stock we have two novelties KRISTALL 511 Sn95,5Ag3,8Cu0,7 (593132) (diameter 1mm, 500g) and KRISTALL 511 Sn96,5Ag3,0Cu0,5 (810050) (diameter 1mm, 500g) solder wires. Technical details can be found in the Kristall_511 datasheet.

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.
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.
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.

In a bid to encourage greater use of TI’s Programmable Real-time Unit (PRU) built into the Sitara AM335x and AM437x family of devices which power the BeagleBone Black development board Texas have announced the PRU cape. The PRU is made up of dual 200 MHz coprocessors, implementing a low-latency subsystem optimized for deterministic, real-time processing allowing direct access to I/Os. It would be fair to say that this capability is seldom used by BeagleBone developers because it has been found to be complex to program.

Headless Ghost is a display emulator (dummy plug) that fits discreetly in to a HDMI socket.
It fixes a problem you probably didn’t even know you had – unlocking the full potential of your graphics card hardware.
By simulating the presence of an attached display, Headless Ghost allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be disabled when there is no screen available.

Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime.
If we should mark an electronic component by a term “sympathic”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is:
- slim (5mm), so it doesn´t take much time on a PCB (only 100 mm2)
- relatively low profile (12mm), so it´s usable in majority of applications
- very sensitive (110 mW), operates even at 54 mW
- handles 5A/250VAC but thanks to bifurcated gold-plated contacts doesn´t have problems neither with small signals
- outstands by long mechanical and electrical lifetime
In praxis it looks so, that on a small PCB space, where we´d usually fit 3 common relays, it´s possible to assemble 10 pcs FTR-MY.
Despite small dimensions FTR-MY has an isolation strength of 3000VAC. Even thanks to a low power consumption, max. operating temperature is +90°C and at the same time FTR-MY enables dense assembly without worry about overheating.
The last bonus of FTR-MY is a considerably affordable price. By its specification, this series is comparable (or even better) with series NY.

Panasonic Corporation has developed a pin-shaped Lithium Ion battery (CG-320, nominal capacity 13mAh) with a diameter of 3.5mm and a weight of 0.6g.
This offering will give designers an added choice to their power sources for new designs among paper and thin film batteries but is not an earth-shattering battery breakthrough. EaglePicher has had small LiIon batteries for implantables for a while and Quallion has a 2.6mm diameter by 10.9mm height in their QL0002l device for implantables and sensors—BUT—it has only 1.5 mAh capacity.
