Enclosure 1455 NHD won’t be scared by a hot summer

obr1744_1

The latest extruded aluminium enclosure from Hammond production – 1455 NHD is suitable even for devices requiring more intensive cooling.

The latest addition to the family of the popular 1455 enclosure series is the enclosure with “NHD” suffix – where “HD” marks “Heat Dissipating” design. Six fins (zones) with cooling ribs significantly improve cooling. With its “N” size it´s suitable for PCB of the “Eurocard” size (100x160mm).

Possibilities of the new enclosure
They´re really wide. Thanks to seven inner slots, it´s easy to find a suitable position for your PCB. Removable front panels consequently secure a PCB against movement and at the same time they can be easily machined by drilling/ milling for usage of various connectors, switches, LEDs,…

And it´s still not all …
As the body of the enclosure consists of two pieces – with a removable base plate, it provides excellent reach to inner electronics even in case, when we don´t want to remove the PCB from the enclosure. The enclosure also contains six internal and two external T slots enabling installation of various components inside (by fixings sliding into the slot) or enables fixing of the enclosure to a panel/wall or similar.
Upon request we´re able to provide you any of the two versions – 1455NHD1601 (natural elox) as well as 1455NHD1601BK (black).

Visaton Exciter – an exciting loudspeaker

obr1743_uvod

A loudspeaker without a membrane which can be mounted on any flat surface solves aesthetical and technical problems.

Fans of HiFi sound and similar „audiophils“ usually don´t cover their loudspakers and surely not their membranes. Firstly, to cover a beautiful top-class loudspeaker is almost a sin :-) and naturally all that stands in a way of sound usually influences it in a negative way.
However, totally different situation is in traffic, audio bells, industrial conditions, in various kiosks (POS) and other applications. Here a loudspeaker is usually mounted behind various covers so as to be protected from mechanical damage. For these applications we can use various industrial loudspeakers which are available in dust- and water-proof versions.

If we go even further, applications where even a perforated loudspeaker cover is undesirable – weather from aesthetical or a technical point of view. For these purposes German company Visaton offers elegant solution – “Exciter”. Visaton Exciter is in fact a loudspeaker without a membrane optimized to be mounted on a flat panel, where by a mechanical connection with a given surface a final “loudspeaker” arises.

EA DOGS displays – small by size, big by features

obr1742_1

Minimum power consumption, very good legibility and a lot of versions – these are the EA DOG displays.

When we speak about “versions” – in case of EADOG from company Electronic Assembly it means a lot of “glass” types (STM, FSTN, transflective,…) and what is unique – many s display + backlight combinations. Right thanks to this unique possibility to make your own combination display + backlight according to your needs make the EADOG series so versatile. We can find here extraordinarily thin and compact graphic and character displays:

  • 1×8 – 2×16 – 3×16 for +5V or +3.3V power supply
  • 4×10/2×10 – 4×20 for +3.3V
  • Graphic 102×32 .. 240×128 for +3.3V

Character displays are with the SPI interface, some are also with I2C, and 4/8 bit. Simple 3,3V or 5V power supply further simplifies their usage.
In the EADOG family can be found „S“, „M“, „L“ and „XL“ series (EADOGS, EADOGM,…). The smallest one – EADOGS is suitable even for miniature applications, where a place is precious, but still a display is desirable or necessary there. On stock we keep three graphic versions 102*64 px with 33,6*23,4 mm active area. The newest member in the family of these small displays is the EA DOGS104-A character display (4×10 with a small font or 2×10 with a big font), while the character height may be changed by software. EA DOGS104-A is in standard equipped with 3 character sets (EN, EU, cyrilic).

The easiest way how to start development is to use the EA 9780-3USB development board.

Kristall 511 solder wire won´t dirt your PCB

obr1643_uvod

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.

UT204 is able to measure DC current and also True RMS

obr1579_5

Clamp multimeter UT204 measures reliably even in real conditions of nowadays mains supplies and for an affordable price moreover.

UT204 from company UNI-Trend is a near relative to the UT203. multimeter. Already UT203 provides a lot of user comfort and a very pleasant feature – measuring of a DC current without interrupting a measured circuit. However UT204 is different from its “weaker” brother in one essential thing – it enable measuring of a true RMS value of alternating signals (TRMS).

As we know, usual multimeters usually deploy a simple rectifier and an RC cell and they´re calibrated to show an effective value of AC voltage – supposing an ideally sinusoidal shape of a measured variable.

In many cases, a non-TRMS multimeter is fully sufficient, but still more frequently we meet devices, which by their power consumption significantly deform originally sinusoidal shape of a mains line voltage. A vast majority of new devices is equipped with switch-mode power supplies deforming a sinusoid, as they draw current for charging of input capacitors mainly on a top of a sinusoid. This situation is partially better at power supplies with a power factor correction (PFC), but even in these cases it´s never an ideal load. At any difference from an ideal sinusoid the accuracy of a common meter significantly drops down and the error can exceed tens of percents. Similar situation is also at various DC/AC inverters (for example 12VDC/230VAC), whose output is usually only an approximated sinus.  

That´s why if exact measurement matters to us, it´s more certain to measure by a device equipped by a TRMS measurement. There are many types with this function on the market, and in a segment of clamp multimeters it´s for example the above mentioned UT204, which moreover offers a lot of other functionality for an excellent price.

Detailed information and comparison of UT203/ UT204 will provide you the UT204 datasheet and the UT204 datasheet and UT203-204 user guide. We keep Uni Trend UT204 as a standard – immediately available item.

WXR3031 rework station will replace you three devices

obr1740_1

Soldering, deslodering, hot-air works but also a record of your work in a PC – this is the Weller WXR 3031.

Good soldering station is usually a fundament of a workplace. Desoldering station is usually a necessity if you work in development or service. And a hot-air station? – this one is becoming a must at any development or rework of PCBs with SMT components. If we already know, that it´s ideal to have all these three device on a workbench, couldn´t they be integrated into one device?

The answer can be Weller WXR 3031

Right at the beginning it can be said, that in this case a connection into one station brings real benefits, rather than well-known negatives of various „3in1“, „7in1“ and similar products and agents :-).

Perhaps the biggest benefit is saving of space on a workbench and the same control interface for all tools. If you´re familiar with Weller WX2 stations, which we introduced to you in our articles, then you know, that they belong to a very top segment. If we “add” to them a section for a hot air, as well as other additional features and a possibility to connect a vacuum pickup, we receive a top class device which makes every electrician happy.

Briefly:
  • 3 channels
  • 420 (600W) total power
  • temperature 100-450 (550) °C/ 200-850°C (hot-air part)

Available are 4 soldering tools (from micro up to powerful 200W) and 3 tools for desoldering. Concretely WXR 3031 set contains:

  • WXR3 unit
  • hot-air tool WXHAP
  • desoldering tool WXDP 120
  • soldering tool WXP 120

A big benefit for professional workplaces is also a possibility to record your work (traceability – temperature profile) over the USB port to a PC. USB port also serves for a possible firmware update. WXR3031 features intelligent identification of a connected tool and a parameter memory built-in in a given tool, intelligent power save function and a possibility to control several additional devices via the WX port.

WX series meets all requirements for demanding and precise everyday work. High power, user comfort and a wide range of soldering tools and tips will be probably beneficial even for your workplace.

Possibilities of the WXR3031 are very wide and perhaps best illustrated in the attached video. Detailed information will provide you the WXR3031 datasheet , user manual WXR3031 and the “WXR3 Quick start”.
WXR 3031 station was incorporated into our standard stock offer.

Have you ever seen a fan resistant to dust and water?

obr1736_p770

New series of Sunon fans with IP68 protection brings reliability even to conditions, where a usual fan doesn´t withstand too long…

Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation in a dusty or corrosive environment. In a usual dry and relatively clean environment, this scenario is not that dramatic and high-quality fans hold on to work for many years without problems. However, it can be also said, that common industrial environment is quite far from an ideal = clean one.

So, which fan to use?

The first good advice might be to use a quality fan, for example from companies Sunon or EBM-Papst. Company Sunon this time declares, that they shifted a level of lifetime and durability a step higher… They “wrapped” all the motor into a „high-tech“ coating and incorporated a mechanism for automatic dust removal from a motor part.

And the result?

The fan works reliably even after a 60 minute ingress into water and into 1m depth. That´s only a small example demonstrating features of the new series with IP68 protection. New series carry GExxxx or GFxxxx marking and they´re available in three sizes – 80x80x25mm, 80x80x38mm and 90x90x25mm. All types are equipped by two ball bearings.
On stock we have types – GF80251B1-AE9 ( 80×25 12VDC 3,96W 101,9m3/h) and GE80252B1-AE9 ( 80×25 24VDC 4,8W 101,9m3/h). Upon request we´re able to supply you also other types.

Even you switch ecologically?

obr1735_p765

More exactly, we talk about switching-off a device. Marquardt 1550 Eco Switch enables this extraordinarily easily.

Do you know a situation, when a seemingly usual thing is fact not that usual… Whether it´s a car with a hybrid drive or a lot of devices which we meet every day – usually in every segment can be found something “inconspicuous” but in fact unusual and exquisite. This is exactly the case of the 1550 Eco Switch series.At the first sight – a usual rocker switch of this series is able to switch off a device in a pre-defined time or it can be switched off remotely – by a pulse (4A/250V, 10ms). Both cases result in a physical contacts disconnection, what´s advantageous from a safety point of view (total galvanic isolation and overvoltage protection) as well as from a zero power consumption point of view. In case of a remote-off version a given switch can be controlled also by the controlled device itself (which is powered through this switch). In this case it results to self “cut-off” of a device and it can be switched on again only physically by an operator. A typical example of use can be a safety function of temperature monitoring inside a device which is able to switch off itself in case of a fault.

1550 Eco Switch series can be used not only for power supply line. The contacts reliably switching even small DC voltages enable usage also for transition of various control signals and similar.

Detailed information will provide you the Marquardt 1550 Eco Switch datasheet and Marquardt 1550 versions.
