Transponder Coils (TR4308I) is The Key of Radio Frequency Identification (RFID) System. DeMint (TR4308I) RFID coil series is specified for RFID applications for the best performing designed at 125 kHz. The (TR4308I) covers a wide range of electrical performances and offers better sensitivity, greater read distance and higher SRF than other coils its size.
The TR4308I's length and cross section area are optimized for best sensitivity in the coil axis. The coil is wound on a plastic base, providing great durability and allowing this part to withstand harsh mechanical shock. With operating temperature range to 125°C, these coils are ideal for a wide range of applications.
Radio Frequency Identification (RFID) is the system of using radio signals to send information identifying a particular situation or item. DeMint (TR4308I) is suited for wireless data transmission in low frequency RFID products, such as immobilizers, TPMS, keyless entry. Other industrial applications include access control and tracking devices.
In addition to our standard models, DeMint can design RFID coils to operate at other frequencies. Customized inductance values are available on request. Download complete specification (TR4308I) PDF (395KB).
