The highest communication speed UMTS/HSPA+ and an easy communication via USB make the new module ideal for M2M applications.

Fast data transmission is becoming an inseparable part of devices for automotive industry, measuring, tracking, security systems, wireless terminals (POS), mobile computers etc.

When we´re choosing a module for above mentioned segments, it´s surely worth if the module also offers somewhat so to say “extra”. In case of the UC20 module it´s true, because there´s probably no parameter, which would the UC20 not meet and when you look closer at the datasheet, you´ll also find another functions like for example 2x 15 bit AD converter and other. A big advantage of the UC20 is, that it supports a fast transmission even outside of the 3G networks thanks to a dual mode (+ Multi-band) for WCDMA but even GSM with a support of GPRS/EDGE Multi-slot Class 12. A considerable benefit are also the Windows USB drivers (Linux and Android drivers are in development).

  UC20 can air itself even with a high sensitivity and a high integrity of transferred data even in adverse conditions. For a development support, there are also available reference examples – UC20-reference design as well as UC20-Compatibility design regarding HW compatibility of UC20 with the M10 module.

All package (12x pdf) of software user guides can be downloaded on this link (11MB). Detailed information will provide you the documents UC20-Specification, UC20-Presentation and UC20 Hardware design.

For many applications can be beneficial the UC20 module on a PCB in a form of the Mini PCIe card. Also available is the UC20_EVB development board.

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 don’t need to 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.

When observing basic rules will the top quality AGM VRLA batteries last you up to 15 years – we will advise how.

This description could start by a long list of technical improvements of Panasonic batteries. thanks to which they gained a stable place on the top of development in this segment (AGM, expanded positive grid. additives for regeneration from a deep discharge, self-extinguishing container material,…).

However those are things, which can be easily checked up from available internet source or even better from satisfied users. Instead of it, we better bring you a few advices for usage of VRLA/ SLA batteries to serve you as long as possible:

  • batteries can be recharged by several ways, but one of the most reliable belongs a „constant voltage/ limited current“ method, i.e. observing max. 2.45V/ cell and a current limitation. It responds 14.7V at 12V battery and a max. current of 0.4CA. This is suitable at so called cycle usage.
  • at a stable connection to a voltage source, a voltage per cell shouldn´t exceed 2.3V what is 13.8V at 12V battery. Current limitation should be set to 0.15CA.
  • battery lifetime grows significantly with a decreasing temperature, i.e. it is very important to place a battery far from heat sources (transformer,…)
  • number of cycles (thus a battery lifetime) is very strongly dependent on a level of discharge before consequent recharging. Dependence is so strong, that for example at discharging to 50% a standard battery will reach a lifetime of approx. 500 cycles, while when discharged in 30% (remains 70% of capacity), the number of cycles will increase up to 1200 (!). The result is, that a choice of a suitable capacity is a key to reach a good lifetime in a given device. Especially in devices, where a battery is daily discharged/ recharged, can a suitable battery (with a higher capacity) significantly prolong a lifetime (thus minimizing costs for replacement).
  • if possible, avoid usage of battery on 100% discharge (so called deep discharge). Even though Panasonic batteries manage these statuses and they contain additives for a successful recovery from a deep discharge, but such a usage shortens battery lifetime significantly (to approx. 200 cycles).
  • real capacity of a battery (amount of energy, which we´ll get out of it) is strongly dependent on a discharge current. 100% capacity can be reached at a current of 0.05CA/ 20°C. At 0,25CA current it is approx. 75% of capacity and at a current of 1CA it is only approx. 55%. This fact also says for a sufficient sizing of a battery. Especially in applications with a relatively higher power consumption (approx. >0.05CA) we´ll gain by using a 50% bigger battery a resulting battery, with a capacity “increased” in more than 50% (thanks to a relatively lower load of such battery at discharging). Resulting relatively lower discharging current and a lower depth of discharge in every cycle will significantly contribute to a longer lifetime..
  • real capacity of a battery also depends on temperature. Difference between a capacity at +20° vs. -10°C is approx. -25%.
  • cut-off voltage at which it´s necessary to disconnect the battery is markedly dependent on a discharge current (at a higher current it falls down). That´s why it´s good to set a deep discharge protection in respect to a supposed maximum discharge current.

Above mentioned values apply to standard Panasonic batteries. In the offer of company Panasonic can also be found types with extra long lifetime as well as sa called „Power“ types, suitable for high current devices (UPS,…). On stock we keep a few selected types of Panasonic batteries and upon request, we´re able to provide you any other type. Detailed information about usage and an overview of the Panasonic portfolio can be found in the VRLA Handbook document.

Universal multimeter UT139C with a high resolution will be appreciated at development and everywhere, where you need to find out a situation in a given device accurately

Imagine a situation, when you need to check or set a voltage of 3.3V or 5V usual at digital electronics (AD converters reference,…). Or to measure the end of recharging of Li-ion/ Li-Pol batteries at 4.20V when it really matters on every miliVolt. In these cases, with usual multimeters you´ll face one cardinal fact – regarding that the most of them has a max. display reading of 1999, you´ll measure in hardly the first quarter of a range, thus with a significantly lower resolution. For example instead of desired 4.001 V (3 decimal positions), you´ll only see 4.00V. Naturally, we don´t always need such a high resolution but many times an improvement of resolution in one magnitude can provide us a worth information about a real situation in a measured circuit. In these situations it often doesn´t matter on the absolute accuracy that much, but right on a resolution, especially when comparing voltages in two points, increase/ decrease…

From this point of view is the novelty in our stock UT139C an excellent device providing besides a high resolution (5999) also another features worth to notice, for example: TRUE RMS measurement in a range of 45Hz-1kHz (to 400 Hz with VFC filter activated), measuring of high-capacity capacitors up to 99.9 mF (99 999 uF), measuring of duty cycle in a range of 0.1% – 99.9% and other. Not quite common is also measuring of uA and mA even in AC range. Function Rel is useful even at measuring of small capacitors, where it´s able to eliminate “offset” caused by a capacitance of testing leads.

A thermometer (K type) with arrange of -40 to 1000°C can also be useful at development. From some point of view it´s advantageous supplying by two AA cells, not by a classic 9V battery (AA cells have a better capacity/ price ratio).

UT139C is also able to serve as a non-contact AC voltage tester (NCV), indicating in 4 steps a proximity of >100VAC voltage. . Indication is by a red LED in the upper part of display, by a display (-,–,—,—-) and by a buzzer.

Further information will provide you the UT139C datasheet.

How does it work? Below mentioned items can be found in our store two times – with a standard description and also with a „PRINT“ suffix.

1) If you intend to buy only the bare – unprinted material, you can do it on items without the „PRINT“ suffix.

2) If you wish to get a material printed according to your demands, choose a desired item with the „PRINT“ suffix and enter a number of pieces of cards (it´s possible to buy only whole cards). Don´t get confused by an amount “zero” on stock. It is intentionally. After placing an order we´ll contact you regarding sending files in an appropriate form (picture, table, …) and we´ll agree details regarding printing. The price at a given “PRINT” item represents a price for printing (preparation to print, editing, printing) as well as the price for material thus being an end price for you.

Material, which can be used at the moment is:

US-EML(20X8)PRINT – white self-adhesive labels (Polyester, -40…+150°C) with the size of 20x8mm (64 pcs/card) suitable for marking of devices and goods with a flat surface.

US-WML6(13X13)PRINT – self-adhesive labels (PVC, -50…+110°C) suitable for direct marking of cables by sticking/winding around a cable. There are 32 labels on one card with a white field for printing of the 13x13mm size. Transparent self-adhesive part (longer than a part dedicated for printing) protects marking from contamination and abrasion. Suitable for wires up to 6mm diameter.

US-WMT(15X4)PRINT- universal easily applicable cable markers (PVC, -30…+80°C, UL94-V0) for insertion into PATO and PATG carriers. PATG carriers are transparent extra reliable marker carriers, which have to be pushed onto a conductor before it is connected into a terminal block PATO carriers are clip-on type, i.e. it´s possible to clip them to a cable, which is already inserted into a terminal block. From both series of carriers we keep in stock two types covering 2.8 to 7 mm diameters.

UCT2-TM5/6PRINT – plastic markers of the UniCard series (PC, -40…+120°C, UL94-V0) characteristic by a simple application and an easy separation. This concrete type is suitable for Wago terminal blocks of the 2002…2006, 280, 281, 290, 780, 781 and other.

This interesting spray from the Kontakt Chemie portfolio will serve in an office but also at the production of electronics and in many other segments.

Name “Label off” discloses a main purpose of usage of this spray. But that´s not all. Because Label Off is a mixture of solvents which particularly well dissolve sticky substances, it can be successfully used everywhere, where it´s necessary to remove residues after adhesive tapes or other hard-to-remove substances like tar and tree resin. Despite a considerable effect, the spray is considerate to many plastics, only can´t be used on polystyrene and polycarbonate. Label Off can be even used on a cardboard/ paper boxes.

Label Off acts very simply – all that is necessary is to spray a thin layer to a label or other place, which we want to clean and wait approx- 2 minutes. After this time it´s usually possible to peel-off a label without residues. Occasional residues can be removed by a repeated application of Label Off and wiping by a (paper) cloth.

Detailed information will provide you the Label Off datasheet.

“Power bank” or a mobile power supply with a USB output can contribute also to your undisturbed work. 

Nowadays already almost every battery-operated device with a USB port has a possibility to be operated or recharged through this port. Whether it is a smartphone, external harddrive, various modems, dataloggers and many other specialized devices, almost all of them can be powered/ recharged also from a USB port from an external mobile power source -”Power bank”.

In respect to the fact, that there are still more devices with this possibility, we incorporated to our stable stock offer two types of these power supplies – B110 and B120 from a renowned company Apacer. They differ mainly by a capacity of an in-built battery (4400/ 6600 mAh). B110 has one USB connector with a max. output current of 5V/1A, while a bigger type – B120 features two USB ports with a max current of 1,5A/1A (max 2.1A both ports simultaneously). Both Power banks can be recharged through a micro USB port by means of a supplied short USB cable enabling recharging for example from PC, USB adapter or from still more used wall USB outlets, which are becoming a common part of modern buildings installations, on airports etc. The same micro USB/USB B cable can be consequently used to connect a device which we want to power/ recharge (through an “OUTPUT” connector). A small complement of both types is a 5mm white LED, thus B110 and B120 can serve as a small torch with a long hold-off.

Overview of features of both types can be found in the Apacer B110 and B120 datasheets.
