New movement detectors (PIR) represent a Professional solution with up to 30 m range and wide possibilities of assembly.
On the market, there are many movement detectors based on a PIR sensor. For a simple usage, like for example lighting of a garage entry. Probably, it´s not necessary to use a top quality sensor with exactly defined specification and with wide possibilities of adjustment if you´d like to use it for example for a simple lighting of a garage entry. But a for a frequented corridors, security devices, lighting switching, … it´s surely beneficial if having a detector which we can rely on. Detectors from company Finder belong to such category. Finder offers five basic series:
● 18.01/18.11 – detector with a wide detection angle and a universal assembly with a possibility of an easy selection of a spce to survey. Typ 18.01 is suitable for indoor applications, 18.11 also outdoor.
● 18.21/18.31 – detector for ceilings with a surface or recessed assembly
● 18.41 – detector for hotel or office corridors, up to 30x4m range (depending on a height of a ceiling)
● 18.51 – highly sensitive ceiling type with a square detection pattern (up to 8x8m), suitable for schools, offices and also low activity zones. High sensitivity enables operation in 2 modes – “presence” and “movement”. In this case even a minimum movement, like for example a work on a PC is sufficient to activate the detector. Such a sensitivity can help to prevent for example an unwanted locking of building and activation of alarm, when you already think, that there´s nobody inside (but in fact, somebody is still there :-)).
● 18.61 – specific product for a wall assembly, 180° angle of survey, detects a half-circle with up to 18m diameter.
All types have elements for adjustment – ambient light sensitivity and a switch-on time of a contact (from a last detection). New types – 18.41, 18.51 and 18.61 also have the third adjusting element – sensitivity of the sensor itself. Thanks to them, it´s possible to adjust a detector to meet requirements of a given application. Logic of switching is an “addition”, i.e. if in time of a switched-on contact occurs another detection, the sensor will prolong the switch-on time for the selected time, i.e. no switch-off of the output contact (neither a short one) will occur. All types are designed for mains applications (96-253VAC) and they have a relay output (10A contact). Contact at types 18.41, 18.51 and 18.61 is also able to switch 400VAC.
Types 18.41, 18.51 and 18.61 are supplied with a rich set of accessories enabling a comfortable and aesthetic mounting as suspended ceiling, recess mounting (for example into a wall) and surface mounting.
Detailed information will provide you the Finder 18.01-31 and Finder 18.41-61 datasheets as well as the Finder 18 flyer (DE) and the attached video.

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.

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.
