RFID Key Fob arung arai lata ai lam: Range, prat galu ai lam, manu jahpu hpe hti na matu ginra lam matsun

ABS gaw shi a default status hpe nsen a majaw lu la ai: manu n law ai, n-gun n law ai, nta kata chyinghka ni a matu ngang kang ai lam law law nga ai. Raitim, quote langai hta "ABS" ngu ai gaw, masat da ai lam n re. Standard ABS, UV-stabilized ABS, hte PC/ABS kayau ai gaw shinggan hte katsi ai shara ni hta grai shai ai hku galaw ai majaw, gara supplier hpe raitim san ra ai ga san gaw .gara tsang, gara dinghku hpe sha n-ga. Anhte aABS RFID sumri nidai lam a majaw grade hku nna masat da ai; dai generic "durable" ngu ai masat kumla gaw n rai yang, nbung katsi ai hte UV shagan hpe line item galoi mung n shapraw ai.

Spec sheet hta galoi mung n tsun da ai daw: hti na ginra

Ndai kaw gaw, antenna ni hpe tune galaw ai masha ni galaw da ai fob hpe, manu jahpu langai hpe hpawng de da ai kaw nna garan ginhka ai detail hpe tsun dan ai. Dai nta gaw antenna a wan n-gun makau grup yin a daw langai mi rai nga ai: coil langai a nsen n-gun gaw shi a grup yin na dielectric hta madung nga ai, dai majaw epoxy hta n-gun n rawng ai inlay hpe potting galaw ai, shing nrai, grau tsaw ai-dielectric shell hte shinggrup da ai gaw, dai nsen n-gun rawng ai shara hpe galai kau ya ai. Encapsulation gaw, electronic ni hpe sha makawp maga ya ai n re; shanhte hpe retune galaw ai.

 

Hka htung -hprawng ai line gaw antenna a inductance hte tuning hpe shadawn aingut sai, shinggrup da ai daw htahte design hpe gram lajang ya ai majaw, resonant frequency gaw protocol ra ai shara de bai hkrat wa ai. Dai gaw, hpang jahtum na shingdu shingwang kata kaw pat da ai HF (sh) NFC coil langai ngai a matu, practice galaw ai chip dut ai ni a laika rai nga ai (Texas Instruments antenna hkrang shapraw ai lam matsun). Npawt tara gaw kadai hpe mung manu jahpu n jaw ra ai. Datasheet kaw na nang n mu lu ai lam gaw, na a laksan unit hpe ngut sai daw hku nna shing nrai, n-gun n rawng ai inlay hku sha tune galaw da ai kun, dai majaw hka n shang ai RFID key fob material hpe n hkap la shi yang, hpang jahtum na sealed galaw da ai daw hta shadawn ai read-range sumla hpe san yu u (inlay nambat n re ai), go { it}off hte {4 off ngu ai masat kumla hpe jat bang u.

Metal RFID Key Fob hti lu ai shara: Hpa majaw metal gaw plastic hta grau sawng ai hku hti lu ai

Client ni gaw magri fob ni hpe hpyi ai gaw magri gaw quality hpe madun ai majaw re. Dai shaloi read range gaw hkrat sum mat nna kadai mung hpa majaw re ai hpe n lu tsun dan ai. Physics gaw mara raw ya lu ai lam n nga ai: coil makau na conductive npu gaw, field hpe hkap la nna, n-gun hpe nhtang shapraw ya ai, resonant frequency hpe target kaw na gang je kau ya ai eddy current ni hpe hpaw ya ai. Effect gaw kaba ai, marginal n re. Hpyen n-gun n law ai -reader langai a matu ka da ai bench data gaw, nominal range gaw inch 24 daram kaw nna 5, 6 daram de hkrat sum mat ai hpe madun dan nna, dai lamu ga hpe bai gram lajang na matu ferrite layer hpe kalang mi jat bang ai shaloi she 20 daram de bai gram lajang wa ai (US Patent 6,307,517). Kaji ai HF hte NFC coil ni gaw, grau nna hkam sha chye ai, metal RFID key fob read range sum mat ai shaloi, grau nna hkam sha chye ai.

Dai fix gaw exotic n re, raitim dai hpe ndai hku galaw ra ai: coil hte metal lapran na n-gun n rawng ai ferrite (sh) ferromagnetic isolation layer gaw sum mat ai tsan ai shara law malawng hpe bai gram lajang ya ai, dai layer nga ngut ai hpang antenna hpe shi hte rau tune galaw ra ai, hpa majaw nga yang isolator gaw coil a inductance hpe mung galai shai kau ya ai. Metal fob hpe atsawm sha galaw ai gaw antenna-kaji langai mi re. Generic inlay grup yin hta casting hku galaw ai metal fob gaw byin na matu la nga ai bai nhtang wa ai lam re. Dai majaw, n-gang nta langai hpe sign off n galaw shi yang, na a reader model hta chyam yu ai tsan ai shara hpe san yu u, nang teng sha lang na keyring hte mounting hte rau. Free-nbung bench nambat ni gaw galoi mung shi hpe flatter galaw na re.
