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‑tekniken bygger på radiovågor som aktiverar och läser taggar utan fysisk kontakt eller siktlinje. Det gör den snabb, pålitlig och ekonomisk för automatiserad spårning och datainsamling – exempelvis vid inventariehantering, tillgångsspårning, produktion eller tillträdeskontroll. RFID har funnits i över flera decennier och fortsätter vara i framkant tack vare minskade kostnader, förbättrad räckvidd och flexibilitet i användningen – från passiva taggar till batteridrivna varianter med lång räckvidd. Teknikens standardisering, integritetsskydd och höga tillförlitlighet gör den fortsatt mycket populär
Under vårt varumärke Craycom erbjuder vi en hel serie RFID-produkter: intelligenta taggar och specialbyggda läsare (handhållna och fasta) som fungerar i riktigt tuffa miljöer – även utan extern strömkälla eller kablar. Plattformen är modulär och kan snabbt anpassas för kundspecifika behov, vilket begränsar både kostnad och time‑to‑market.
RFID-läsare vi utvecklat:
Najad – industriellt kapslad läsare med antennkrets för långa avstånd och kommunikation via Ethernet, RS232, RS485 eller RadioLan
Dyname – fabriksinställd för specifika taggtyper, enkel men kraftfull för långdistansläsning i krävande miljöer
Galene – diskret design för fordon med inbyggd antenn, monteringsvänlig form och mjukvara anpassad för anslutning till fordonsdator.
