Well-proven embedded mini PC with Windows CE – BEGA220 are now available in the IP66 protection class.

Bega220 as a universal microcomputer with an OS and a 7“ touch display already found its place in many applications. Now company Bolymin launched on the market an improved version resistant to dust and water (IP66) – the BE220C module. IP66 resistance applies to a front side and a bezel, what´s in the vast majority cases fully sufficient, because in praxis the module is always installed into a target device.

BE220C maintains all features of the Bega220 series. Functionality, interfaces and pinout of a communication protocol are the same. BE220C is supplied with a cable for connection to a communication connector on a bottom side of the module and also with a USB reduction (for connection of a keyboard or a mouse). The module should be powered by a 12V/1-1,2A adapter with a 5,5/2,5 mm DC connector. Also supplied is the CD with a user manual, software development kit (SDK) and code examples.

BE220C can be used (similarly like Bega220) for control of any devices or processes while maintaining an advantage of an easy programming in the Windows environment and compatibility with widely available software for a PC.

Detailed information will provide you the BE220C flyer and the BEGA220 user manual.

Company Quectel brings to a market its first high-speed module EC20 which you can try yourself. More than fifty developers worked for over ten months on this module.

We´d like to share with you its parameters, as well as hints, which can make your work with this module easier – this is our biggest bonus to sale of modules from company Quectel.

Are you interested in compatibility with previous modules?

Module EC20 arises from the M10 GPRS module and the UC20 UMTS module. These modules can be designed to a PCB in a way that you have ensured variability and a possible replacement in case, that you wish to have one board for several solutions …

From theory to the praxis…

Discussions about LTE already last for some time. One LTE transmitter (800MHz) manages up to six times bigger area than one UMTS transmitter (2100MHz). LTE protocol is already from the beginning (in contrast to UMTS) written as a high-capacity with a fast response. The first phase of area coverage is usually equal to speed of UMTS uplink/downlink. After reaching almost a 100% coverage, then usually starts the second phase, which actually speeds up to current theoretical speeds of 172,8Mbps (downlink) and 57,6Mbps (uplink).

Let´s have look at frequencies

In presence, 4 bands are functional – on frequencies 800/900/1800/2100MHz and the 2600MHz band is not used so far. EC20 manages all these bands. EC20 will be produced in 2 versions, as EC20-E (for Europe) and EC20-A (for USA). Do you know that in USA also the 1559 to 1610 MHz band was approved, which however should interfere GPS signal in 1525 – 1559 MHz band, according to measurements?

And at last – advantages of EC20
  • No doubt and after experience with developers – the LCC package offering a possibility to assemble by hand or by machine.
  • Module is not the smallest LTE module in the world, but belongs to the smallest LTE ones. EC 20 also incorporates implemented GPS/GLONASS receiver.
  • Supports MIMO technology – multiple-input multiple-output, i.e. – multi antenna systems.
  • The EC20 module is able to communicate via USB port in Windows, LINUX, as well as in Android.
Frequently discussed eCall

The EC20 module also supports „emergency call“. In the time of creation of this article it was decided that eCall will be compulsory in vehicles from April 2018. In every way, company Quectel is already prepared and supports this system in almost all its modules.

The eCall function also related to another advantages and functions in the module, for example:

  • Low power consumption
  • High RF power and high sensitivity <-108.5dBm
  • Fimware can be updated remotely – DFOTA (firmware over the air)

Without problems and directly at connecting a device. How? With a new Euroclamp MPF03 terminal block with integrated fuse holder.

Nowadays, when “almost everything” works on electricity we can see still more devices connected to mains line. That´s why it often happens, that many small-power devices are connected to one (circuit breaker fused) line. To increase a safety, it´s usually advantageous to fuse particular devices separately – for example by small glass fuses. Somewhere it´s advantageous on a panel or directly on a PCB, elsewhere directly in a control relay interface module and in many cases directly in a place of connection.

For this purpose a novelty in our offer is very suitable – 3-pole terminal block MPF03-10, where one of poles is fused by a glass tube fuse 5x20mm. In praxis it can look so, that on a place where you so far used a classic (“chocolate”) terminal block, you can use MPF03 and insert a suitable fuse.

In the MPF series can be found series with 1-5 poles. As already a name says, pin spacing (pitch) of the MPF series is 10mm. On stock we have the 3-pole version MPF03-10 ideally suitable for mains line appliances (L,N,PE). Exact dimensions and further parameters can be found in the Euroclamp MPF03-10 datasheet.

In our portfolio can be found quality knobs from company Cliff suitable for a wide range of potentiometers and encoders.

A device with excellent specification, quality components used, …., but a one step is still missing to reach a great overall impression – it is to use a quality and aesthetic control components.

Probably you´ll agree, that knobs for potentiometers and encoders belong to a “group of critical components”, determining a resulting look of a device. Company Cliff specializes on development and production of these components already from 1977 and considerable experience are reflected in a precise construction and a wide portfolio of components produced.

Directly from our stock, we´re able to offer you a few interesting series:

  • K87MAR – plastic two-color knob with a colored top part and a side line. Available in 8 standard color versions. Thanks to a big popularity and a mass production, their price is very affordable. User friendly, soft – “rubber-feel” surface. Excellent for color coding of potentiometers groups in equipment with many knobs. 6mm „D“ shaft.
  • K87MBR – plastic two-color knob, very similar to series K87MAR, but only a side line is in color. Affordable price and a mild “rubber-feel” surface. 6mm splined shaft or 6 mm “D” shaft.
  • K18 – universal plastic knob for electronic encoders. Available in 5 colors and 3 weight categories. In our stock can be found 2 heavier versions (35 and 50g) in a grey and black color.
  • KMK – universal aluminium knob with a machined aluminium shell and a molded plastic inner. Available in a black or natural anodized surface. Push-on installation. In our stock can be found 4 versions with a 25 mm diameter – KMK25 in a black and silver (natural) color, with a 6mm splined as well as “D” shaft.

Types for splined arbors have 3 relatively robust juts (as visible on a Picture), that´s why they´re suitable only for potentiometers with deeper splines, or with a lower splin count. From our offer they´re suitable for example for Taiwan-Alpha potentiometers and they´re not suitable for potentiometers Piher series PC16.

Further information will provide you the K87MAR, K87MBR, K18 and KMK datasheets. Upon request, we´re able to deliver you more types from the portfolio of Cliff knobs.

Maybe it´s the right time for you to also consider usage of OLED displays in your applications.

The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications extreme thermal resistance a big advantage (immediate response even in frost).

As it uses to be, new technologies are rarely cheap. In case of OLED we can say about significantly more affordable price than a few years ago. For example even despite currently disadvantageous EUR/USD exchange rate, when many components become more expensive, renowned OLED character displays from company Electronic Assembly became cheaper during last weeks.

Naturally even LCD displays still have their undisputed advantages, for example a very low power consumption (EADOG series) and depending on type also a legibility even without a backlight. However in applications where you consider OLED vs. LCD (with a backlight), in majority of cases an OLED is a better choice. OLED is a better choice mainly because of unbelievably wide viewing angle, immediate response and a great contrast, where a black is truly black.

In our offer we have character OLED displays EAW series but also other universally usable OLED displays.
Some types of the EAW series are available in 2 versions – yellow/green and ice white. Detailed information will provide you the EAW flyer and the EAW datasheet.

Audible click, protection against backing out and disengagement together with many versions and attractive price – these are the Power Tripple Lock connectors.

Universal connectors for interconnection of leads (wire-to-wire) as well as leads to a PCB (wire-to-board) are necessary every day and practically everywhere. In industrial applications we usually need various connectors. “Various” usually means almost uncountable amount of types, that´s why it´s usually a big advantage if it´s possible the same connector for several applications. This “versatility” is considerably met by a new series of connectors Power Tripple Lock. Commercial products, industry, transportation – all these segments are addressed by Power Tripple Lock from company TE Connectivity.What does the „Tripple Lock“ mean?
As already the name says, it is a triple locking – protection against disconnection. The basic and the most important is a sophisticated design with exactly mating parts and a reliable lock. Audible click is a discreet but very useful feature contributing to a correct connector assembly.

Optional protections are „CPA“ and „TPA“

  • CPA (connector position assurance) is an optional plastic part – additional lock against mistaken disengagement.
  • TPA (terminal position assurence) is an optional plastic part used from the rear connector side (from leads) ensuring a 100% exact leads, helps precise mating and improves overall reliability and immunity to vibrations and stresses.

Connectors are available with pins in a single row (2,3,4,5), two rows (2×3,2×4,2×5,2×6) and in a matrix (3×3,3×4,3×5) with 6mm pin spacing. Basic parameters are 20A/600VAC or DC. Also interesting is the fact, that connectors are available in three material versions with a different thermal resistance (all are UL 94V-0):

  • PBT standard (-55…105°C)
  • high temperature (-55…150°C)
  • „Glow wire“ (750°C no flame) according to IEC 60335-1

Prevention against improper connectors assembly is a different colour coding of particular material versions. Another factor preventing improper connection are 4 possibilities of keying (necessary if the same connectors are in one device). Power Tripple Lock is a big family of connectors containing connectors “wire-to-wire“ (free hanging leads),“wire-to-board“ as well as panel mount versions.

Versatility of Power Tripple Lock connectors is also underlined by a wide range of usable wires cross sections in a range of 0,34-3,3mm2 (12-22 AWG). A comprehensive overview of Power Tripple Lock connectors can be found in the „Improving appliance connector designs“ flyer and in the „Quick Reference Guide“.

If a production of a professional bezel is over above your possibilities, leave it to us.

Also can be added, that even in case you have a possibility to produce a suitable bezel, it can easily happen (especially at smaller batches) that it simply isn´t worth it. Design, prototyping,… all this costs something. On the other hand we have here a ready-made solution with true brass bushings and precisely designed spring clips. The result is an immediately usable bezel, while it´s only necessary to make a simple cut-out into the front panel of the device. There´s no need to drill mounting hols to exactly defined positions or so. We talk about 4D Bezel-s. Novelty in our stock offer are bezels for 7“ displays uLCD70. Bezels are available in a black and white version. In our standard offer can also be found bezels for 3,2“ and 4,3“ displays from company 4D Systems.Further details necessary for a trouble-free usage in a target device will provide you the 4D-Bezel-70 datasheet as well as other ones at particular types.

Favourite series 1553 hand-held enclosures are now available even in a water-resistant version with IP65 rating.

Ergonomic enclosures of the 1553 series with a non-slipping surface found their place on a market very quickly. Precise construction with brass bushings, stainless steel screws included, easy PCB placing on standoffs and other details make this series of enclosures universal for practically any “mobile” applications.

Despite very well fitting parts of an enclosure minimizing a possibility of a dust ingress into enclosure, there certainly are applications with a higher risk of water and dust penetration. For these cases the new “W” version is suitable, i.e. 1553W with integrated sealing and a whole construction designed so as to meet IP65 requirements. Fixing positions for screws are located outside the gasket ensuring sealing integrity.

Hammond 1553W series is available in “B”, “C” and “D” sizes, i.e. 1553WB (117x79x25mm), 1553WC (117x79x32mm) and 1553WD (147x90x25mm). All sizes are further available in two colours – whit-grey and black (GY/BK). Further details can be found in datasheets at particular types below this article.

New series of Friwo FOX mains adapters meets the most stringent energy regulations already now and at the same time it´s more compact than its predecessors.

DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even here can be expected toughening in the nearest years.

That´s why German company Friwo as a long-term long-term OEM producer of power supplies and adapters comes with a new line of mains adapters named “FOX”. Besides high efficiency, these power supplies are also extraordinarily compact. Already recent series MPP and GPP are very compact, but FOX is a “step further”, as also illustrated on attached picture. System of exchangeable primary and secondary adapters (connectors) enables to use the same power supply for various applications and in various countries.

Even the FOX series meets various international requirements and obtained many approvals. a medical version will be also available soon. The FOX series is a novelty – 12W types are available upon order. Gradually also other types – FOX 18, FOX 30 a FOX 6 will be produced.
FOX series, as the only type on the market that meets criteria for IP42 protection – with selected primary adapters (connectors).
The first type from the FOX series – FOX 12 Office 5V/2200mA (1896623) with the 5V output voltage can be already found in our standard stock offer. As the power supply is designed as “modular”, it´s necessary to also buy appropriate primary and secondary adapter (connector) and the output cable, i.e. for example FOX Adapter/EURO (1844847) , COAXCON5.5/2.1/9.5 (1807700) and FOX Distribution DC-Cord.

GW134T_Frontby elektormagazine.com:

CAP-XX have introduced a range of flat single-cell supercapacitors targeted at small (or disposable) devices for IoT applications. This new Thinline range boasts the world’s thinnest supercap at 0.6 mm thick. CAP-XX use a unique nanotechnology construction that stores electrical charge in engineered carbon electrodes on aluminium foil to minimize resistance and maximize capacitance. This type of electrode construction packs the highest energy and power densities possible into thin, prismatic packages.

The idea was born while working with a customer designing a disposable insulin pump. “We figured out how to eliminate materials and change some processes to reduce costs and thickness,” explained Anthony Kongats, CAP-XX CEO.
