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.

Marking of cables and terminal blocks has never been easier – we´ll do it for you! First 5 customers with a 50% discount.
In line with broadening of our services and support to our products, we offer you a possibility to get off of troubles with printing of labels and other markers for devices, cables, terminal blocks,… We offer you a service of a preparation for print and printing of labels and terminal blocks itself according to your demands.
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.

Over 60 years of experiences of German company EBM-PAPST in the fans development reflects in an uncompromising quality of products.
It may sound like a phrase, but to rely on a quality is almost always worth – mainly because of overall savings. Long lifetime and energy efficiency will at the end of the day reflect into lower operation expenses. Quality materials sophisticated construction, precise bearings and results from long-term tests say in favor of EBM-Papst fans. EBM-PAPST has in its testing laboratories 1500 operating fans and there can be even found fans continuously operating from 80´s (!). EBM-Papst is quite stringent regarding a declared lifetime and in comparison to other producers it declares „less optimistic” values, as illustrated on an enclosed picture. It means, that if we compare 2 fans from various producers with similar features, it´s very probable that the type from EBM-Papst will have a higher real lifetime. In the EBM-Papst portfolio can be found practically all types of fans and blowers, from smallest to massive industrial ones, axial, radial (centrifugal), diagonal a tangential. The most of fans is also available in a version resistant to dust and water with IP54. EBM-Papst is a pioneer in the development of energetically efficient fans with a significantly lower power consumption and a quieter operation, for example the ACmaxx and GreenTech_EC series.
EBM-Papst portfolio is very wide, that´s why we keep in stock only a few most wanted types and any other type we´re able to provide you upon request. To the standard stock items we newly added also the type 7056ES – AC fan with of a 150mm diameter. 7056ES is a well proven powerful type with a ball bearing and an all-metal construction. Precise ball bearings SINTEC feature a constant low noise during all the lifetime and a low sensitivity to impacts. 27W motor contains an external capacitor and a thermal fuse against overload. High air flow – 330m3/hr, i.e. over 90 litres per second make this type a universal choice for ventilation of various spaces or cooling of electronics and similar.

Electromagnetic door locks can be very easily implemented to almost any entry or security system.
We got used, that electromagnetic locks are a common part of entry doors to various buildings and offices. There are several types of such locks on a market, the most often they are a part of a doorframe. Each type has its pros and cons. From some point of view, the most universal are “external” types, which can be easily implemented into any door without a necessity of an intervention to a door construction. Even such types can be found in our offer.
Y280 and Y350 are bulky locks consisting of a module with an electromagnet and a metal plate from a magnetically conducting material, which shall be mounted to a door (usually an upper portion). After switching on a power supply, a strong magnetic field will be created, sufficient to keep the door locked. A force necessary to open a door is quite considerable (2800/3500N) and normally it isn´t possible to unlock such doors by a “violence”. A positive fact is that a metal plate also contains a backstop with a spring damping a noise at locking.
A representative of “to be built in” types, is the type Y100S. It operates on a principle of a metal stick ejection, that´s why even in this case is a holding force very high, limited mainly by a door construction. A big advantage of the Y100S is that the lock already contains a security sensor against premature lock activation. After applying a power supply on the lock, “nothing happens” – the lock gets activated only after approximation of a plate with a small permanent magnet (included in a package),i.e. only after the doors are closed. All three types operate at 12V, types Y280 and Y350 can also be supplied with 24V (overall power consumption remains approximately constant).

From now, you´ll find in our store the top-quality capacitors from company AVX.
A tantalum capacitor may be for many designers a component with a “smell of alchemy”. It´s not used as often as for example electrolytic capacitors, it´s more expensive and it doesn´t hesitate to fire off at improper handling. Despite these facts, it´s used in many devices and features several advantages, which predestinate it to many applications.
Among main advantages of tantalum capacitors belong small dimensions, temperature stability (C vs. t), very long lifetime (self-repair ability), relatively low serial resistance (ESR) and virtually no dependence of capacity on a DC voltage. Their usage is for these and other reasons beneficial in switch-mode power supplies, digital circuits (processors) in a measurement equipment etc.
Tantalum capacitors strictly require observing a maximum ripple current and also a maximum operating voltage. A low ESR can be a cause of extremely high inrush current after connecting to a hard power supply (for example a battery), which is able to damage a capacitor. From this reason, it´s advisable to design a circuit in a way, that this inrush current was limited, or not to use tantalum capacitors as the first – input capacitors. When these basic requirements are observed, tantalum capacitors will reward us with reliability and long-term stable parameters.
We´re glad to be able to offer you tantalum capacitors from company AVX, by which we replace capacitors of our previous supplier. AVX belongs to a top in this segment and its components meet highest criteria. Also positive is the fact that the price of these capacitors is comparable and in some cases even lower to those of previous types.
On stock we keep the universal TAJ series. Upon request, we´re able to provide you also other series, for example the TPS with a very low ESR. Detailed information will provide you the datasheet TAJ and many useful documents regarding max. operating voltage (derating) , max. ripple current and the leakage current.
