RFID (Radio Frequency Identification) är en beprövad teknik som möjliggör trådlös identifiering och datainsamling via taggar och läsare. På ElectroTech har RFID varit en central del av verksamheten sedan starten och är en av våra kärnkompetenser.
Med lång erfarenhet av att utveckla RFID-system för industrin kombinerar vi teknisk expertis med egenutvecklade, robusta plattformar. Det gör att vi snabbt kan ta fram både standardiserade och kundanpassade lösningar, anpassade efter höga krav på noggrannhet och driftsäkerhet, även i krävande miljöer.
Radioprodukter behöver certifieras, vi har god kompetens inom certifieringar, både lokalt och globalt, samt erfarenhet av att konstruera lösningar som uppfyller krav på radiostrålning och relevanta regelverk.
RFID används idag inom en rad olika branscher och applikationer där spårbarhet, identifiering och automatisering är avgörande. I dagens samhälle är det svårt att inte komma i kontakt med tekniken dagligen. Till exempel vid kontaktlösa betalningar eller när du låser upp bilen. Många av dessa tillämpningar bygger på närbesläktad teknik som NFC (Near Field Communication), vilket är en vidareutveckling av RFID för korta avstånd. Inom industrin möjliggör tekniken effektiv hantering av accesskontroll, materialflöden, spårning och produktion i realtid.
Vanliga användningsområden inkluderar lager- och logistiksystem, tillgångsspårning, accesskontroll samt identifiering i krävande miljöer där andra tekniker inte räcker till. RFID lämpar sig särskilt väl där kontaktlös avläsning, robusthet och tillförlitlig funktion över tid är viktiga faktorer.
Genom att integrera RFID i befintliga system kan processer effektiviseras, fel minimeras och spårbarheten öka, vilket skapar bättre kontroll och beslutsunderlag i verksamheten.
RFID bygger på trådlös kommunikation mellan en läsare och en tagg via radiovågor. Taggen, som är fäst på eller integrerad i ett objekt, innehåller ett chip och en antenn som lagrar och överför information. Varje tagg har ett unikt ID, och när den befinner sig inom läsarens räckvidd aktiveras den och skickar sin data tillbaka.
Det finns olika typer av RFID-system beroende på frekvensområde, till exempel LF (Low Frequency), HF (High Frequency) och UHF (Ultra High Frequency). Val av frekvens påverkar räckvidd, datahastighet och funktion i olika miljöer.
RFID-taggar kan vara passiva, aktiva eller semi-passiva. Passiva taggar saknar egen strömkälla och drivs av energin från läsaren, medan aktiva taggar har ett eget batteri som ger längre räckvidd och fler funktioner.
Tekniken möjliggör snabb och kontaktlös identifiering utan krav på fri sikt och är strömsnål, vilket gör den särskilt lämplig i miljöer där streckkoder, Bluetooth eller optiska system har begränsningar.
En av styrkorna med RFID-teknik är dess flexibilitet, något vi på ElectroTech har byggt upp gedigen kompetens inom. Vi utvecklar och optimerar antenner och läsarlösningar utifrån varje specifik applikation, från mycket kompakta antenner på endast några millimeter till större antennlösningar och system med täckning i decimeter och meternivå.
Detta gör det möjligt att anpassa system för allt från integrerade produkter till industriella installationer med krav på längre räckvidd och robust funktion. I kombination med både fasta och handhållna läsarenheter kan vi ta fram lösningar som är optimerade för miljö, prestanda och användningsområde.
RFID (Radio Frequency Identification) – a proven technology that enables wireless identification and data collection via tags and readers. At ElectroTech, we are experts in RFID with extensive experience in developing advanced systems for a range of industrial applications. With our in-depth technical expertise and robust platform, we develop solutions that meet high standards of accuracy, reliability, and adaptation to harsh environments.
RFID technology uses radio waves to activate and read tags without physical contact or line of sight. This makes it fast, reliable, and economical for automated tracking and data collection—for example, in inventory management, asset tracking, production, or access control. RFID has been around for several decades and continues to be at the forefront thanks to reduced costs, improved range, and flexibility in use—from passive tags to battery-powered variants with long range. The standardization, privacy protection, and high reliability of the technology make it very popular.
Under our Craycom brand, we offer a whole range of RFID products: smart tags and custom-built readers (handheld and fixed) that work in really tough environments – even without an external power source or cables. The platform is modular and can be quickly adapted to customer-specific needs, which limits both cost and time-to-market.
RFID readers we have developed:
Najad – industrially encapsulated reader with antenna circuit for long distances and communication via Ethernet, RS232, RS485, or RadioLan
Dyname – factory set for specific tag types, simple yet powerful for long-range reading in demanding environments
Galene – discreet design for vehicles with built-in antenna, easy-to-install shape, and software adapted for connection to vehicle computers.
Nereid is an RF-ID reader specially designed for reading tags in an industrial environment.
A compact format is combined with a robust construction, where electronics of the highest quality are mounted in a housing that protects against mechanical damage, dirt, and moisture.
The keyboard and menu system have been designed with the goal that Nereid should be easy to use even under difficult external conditions. The device’s high computing capacity, which comes from being built around a digital signal processor, enables long reading distances and compatibility with most tags on the market.
The electronics are of the highest quality and rated for extended working temperatures.
Nereid has unique functions such as determining signal strength, calculating rpm, and presenting measured values and trend curves from various tags.
Nereid has built-in communication via RadioLan or Bluetooth, all to create simple and flexible communication with other systems.
