The FineJoin D1339R is a high-performance, gateway-dependent High-Frequency (HF, 13.56 MHz) RFID reader designed for centralized, multi-node deployment via FineJoin industrial communication gateways. Running a proprietary serial protocol over an RS-485 M12 interface, it functions as a highly efficient edge sensor, streaming raw transponder data directly to the upper-level gateway for aggregated fieldbus conversion (e.g., PROFINET, EtherCAT, or IO-Link).
Fully upgraded to support industrial-standard 9 to 30 V DC wide-voltage inputs, the D1339R scales seamlessly within standard 24 V factory power systems. It incorporates a hardware-level auto-tuning engine to guarantee reliable data transmission (up to 60 mm read range) under heavy metallic interference. Protected by a rugged, distinctive yellow IP67 ABS enclosure (45 × 30 × 12 mm), the D1339R represents a cost-effective, easily maintainable architecture for high-density reading topologies, including intelligent tracking, automated sorting, and machine-tool asset tracking.
