RFID keyboard emulators are able to significantly simplify tracking of goods.
“Replacemen” of a keyboard in a form of an RFID module connected to a USB port works very simply – UID of every tag, which will appear in its range will send to a computer – the same way as if we typed it in by a keyboard. SL040A also enables to choose, whether we want the reader to send only data, or also a „CR“ character after every UID (as if an Enter key was hit). It means, that if we already have a software to type in open (for example Excel), the reader itself will fill the cell with data and move the cursor to another cell. SL040A is even able to read data (not only UID) from Mifare tags.
SL040A is also interesting by one feature – on a request from our company SOS Electronic, the producer started to produce also the black version SL040A black.
Detailed information will provide you the SL040A user manual.

New version of a favorite RFID module ID12LA will enable you to implement RFID into your device even more easily thanks to a wide range of supply voltage.
Literally “globally known” with an integrated antenna – ID12 and its familiar like for example ID2 or ID20 have earned a big popularity thanks to a flawless usage and reliability. Perhaps the only disadvantage of this module was narrow range of operating supply voltage, what in praxis enabled only usage of 5V DC. New version – ID12LA solves also this small drawback and the new module works in a range of 2.8-5VDC. This also enable their usage even with a 3.3V logic and for example in battery operated devices (3-4x NiMH, or 1x Lithium cell, …) without necessity of DC converters or a precise voltage regulation.
The module ID12LA (range approx. 12cm), as well as ID20LA (range approx.16cm) are in our stable stock offer, similarly also the Mifare version (13,56 MHz) – ID20MFIA. In case, that you prefer the maximum range, it´s possible to use module ID2 supplied with an external antenna (range up to 30 cm).
Detailed information will provide you datasheets at particular types below the article.
RFID module ID12LA will also abide a lower voltage … – [Link]
A flux in a spray from company Kontakt Chemie is a very useful helper for development and production.
Everyone, who´ve ever tried to solder without a flux and then with a flux, probably has seen a big difference in solder spreading and in a resulting joint quality. This effect is very visible on a PCB with bare copper tracks without any surface treatment (for example at DIY production of prototypes) but there´s also a significant difference at boards with a surface treated by tin (HAL) or by gold (Flash, chemical gold,..).
Maybe you have a question, whether it makes sense to add a flux when it already is in a solder wire? Naturally, fluxes in soldering wires are of a high quality and producers of solders (Stannol, Koki, Multicore,…) try hard to reach uniform releasing at soldering and to show a minimum spatter. Mainly at soldering of small joints this spatter often causes, that a flux won´t get to a solder pad, what significantly embarrasses solderability. The charm of a flux is based on the fact, that it is directly on a solder pad and in the desired thickness, which can be influenced by application.Especially at soldering of SMT components it´s often even impossible to solder by a method “solder wire in one hand, soldering tool in another”, because we usually need one hand to hold a component in tweezers and moreover – often even a 0.5mm solder wire is too thick to precisely dose a solder directly to a small component in for example an 0402 package. That´s why we usually solder SMT components by a method of taking a little bit of solder on a soldering tip and then applying to a component. But here´s a problem, that a flux won´t survive this a few seconds long “journey” but it will degrade by evaporation, oxidation,… In contrast a flux applied directly to a PCB will replace a missing flux from a solder wire and the difference in spreading of a solder is really huge.
FLUX SK 10 (originally called also a LOTLACK SK10) is based on the natural rosin (colophony) and after application it creates a thin layer. This layer makes soldering significantly easier and at the same time it protects from corrosion. That´s why the FLUX SK 10 has wide possibilities of usage as an agent for temporary protection and significant improvement of solderability of PCBs, various contacts, cable assemblies, terminals of batteries,…
A big advantage is, that in a dry environment the FLUX SK 10 can be left on a PCB as a final protective layer. However in a humid environment it undergoes hydrolysis and degrades. In such environment, it´s better to use Plastik 70, Urethan 71 or Silisol 73. Detailed information will provide you the FLUX SK10 datasheet.

With its width of only 5mm is this relay able to switch 6A/250VAC, moreover at a minimum coil power consumption.
Thin as about a block of “Domino” and still so powerful and for a reasonable price – these are narrow relays series FTR-LY. Powerful and still so easily usable even in circuits with a 5V logic … Somehow this way could be described the well proven relays of FTR-LY series.
If you´d like to use a relay of this shape, then the FTR-LY series will probably also fulfill all your expectations regarding lifetime, reliability, low power consumption and other. When selecting a suitable type, it´s good to take in mind a material of contacts – on stock we keep three types (5V, 12V and 24V DC). A novelty in our portfolio – type FTR-LYCA005V has a „V“ suffix, what means AgSnO2 + Au (0.3µm) contacts. The biggest advantage of a golden layer on contacts is a very low minimum switching current through contacts (10mA/5VDC), in comparison to types with a suffix „E“ or „Y“, which have a minimum switching current 100mA/5VDC. Types FTR-LYCA012Y and FTR-LYCA024Y have in summary the same good properties, only they´re not suitable for switching of currents below 100mA (worse self-cleaning ability of contacts).
An advantage is up to 4000VAC (coil/ contacts) isolation and an isolation distance (clearance/ creepage) is 8/ 8 mm. To a reliability even in tiny areas on a PCB also contributes a max. operating temperature up to +85°C and a low power consumption (approx. 170 mW). Types, which we keep in stock are with one changeover contact (1CO, SPDT), that´s why they can be freely used in application where you need an NO or NC contact.
Upon order, there are also available types for socket and the PCB socket (JM-6N). It´s beneficial for applications, where we want to maintain a possibility to easily exchange a relay.

Connectors of the PV, SV and SH series are available in a huge amount of versions and sizes, that´s why you´ll certainly find here a suitable type for you.
A very frequent requirement for a simple and reliable connection of wires to a PCB is actual about as long as the world knows plated copper boards. There are many solutions and producers, thus a choice of suitable type is usually a question of your preferences, requirements of a device, availability, offer of distributors,….
Even in our store can be found various solutions from world-class producers like TE Connectivity (Tyco, AMP), Wago, Phoenix Contact and also from company Euroclamp. Just the last one mentioned – Euroclamp, focuses mainly on PCB terminals, what is reflected in a wide offer. From our experience we can confirm a quality and reliability of these connectors. To the most favorite ones belong series PV, SV and SH, what are plug-in connectors (terminal blocks) for PCB and the mating types for a cable. They´re available in pitches of 2.5mm/ 2.54mm/ 3.5mm/ 3.81mm/ 5.0 mm/ 5.08mm/ 7.5mm/ 7.62mm/ 10.0mm/ 10.16 mm. So as to make you a selection of a right type easier, we bring you a few hints and explanations regarding their description.
● PVxx – main type for a PCB (connector with pins).
Example: PV02 (02-24= number of poles) – 5.08 (pitch of pins) – V (V-vertical, H-horizontal)- M (M-modular, P-closed)
● SVxx – connectors (female) for a cable – intended for connection with the PVxx series
SV02 (02-24= number of poles) – 5.08 (pitch) – P (P – rear wire connection, F- frontal wire connection) – * (additional code, for example „K“= version with side screws)
● SHxx – right angle cable connectors (female) – intended for connection with the PVxx series)
A very useful “complement” of these series is also the SFxx , series, i.e. – a terminal block enabling a “wire to wire” connection (with types SVxx or SHxx). It can be very convenient if we for example want to jump some module and to maintain input and output leads interconnected (enable to make for example various versione of the same product. A novelty in the Euroclamp portfolio is also the PF series – for a PCB (female connector), enabling connection with PF – (male connectors).
A common feature of all PVxx connectors is a relatively high current handling ability – for example 12 (16)A/450VAC at types with 5.0 or 5.08mm pitch and a maximum wire cross section of 4/2.5 mm2 (solid / stranded wire). Body of connectors is made of a rigid self-extinguishing polyamide (UL94-V0) and the connector itself is made of nickel plated copper alloy. Basic color of these connectors is green (RAL6032) but upon order they´re also available in other colors (grey, black, blue, red, yellos, brown and other). A considerable advantage is also a wide range of operating temperatures of -40 to +130°C.
Types with a wide pitch (for example 10mm) are physically the same with types with a half pitch ( 5mm), they only differ in omitted pins and naturally the maximum allowed voltage is higher (750VAC). Perhaps the best idea about possibilities of these „plug-in“ connectors will give you attached pictures. Detailed description can be found in the Euroclamp short-form catalogue, in the main catalogue Euroclamp, as well as in datasheets at particular types.
