The FineJoin D1339 is an industrial-grade High-Frequency (HF, 13.56 MHz) RFID read/write device engineered for seamless integration into distributed industrial networks. Equipped with an onboard Modbus RTU protocol stack over a half-duplex RS485 interface (M12 A-Code 5-pin male), it allows automation engineers to interface directly with mainstream PLCs and fieldbus gateways without complex RF driver development.
Operating on a heavy-duty 9 to 30 V DC power frame, the D1339 features an advanced auto-tuning circuit that dynamically neutralizes metal-environment detuning, ensuring a stable read range of 0 to 60 mm and high electromagnetic immunity (EMI). Housed in an ultra-compact, shock-resistant IP67 ABS enclosure (45 × 30 × 12 mm), this robust reader is optimized for harsh automation environments, including Manufacturing Execution Systems (MES), CNC tool management, and automated sorting conveyor lines.
