Ceiling-Mounted UHF RFID Access Control Reader – JT-RDJ01
The JT-RDJ01 is a high-performance ceiling-mounted UHF RFID access control reader developed by Jintou Technology. Supporting the ISO 18000-6C (EPC C1G2) protocol, it operates across 902–928MHz (with 865–868MHz available on request) and features adjustable output power from 0 to 33dBm.
Equipped with a built-in phased array antenna and advanced positioning algorithms, the JT-RDJ01 can simultaneously determine the entry/exit direction of multiple tags, accurately distinguish indoor from outdoor tags, and deliver exceptional performance in preventing missed reads and false reads. The device supports ceiling mounting, suspension cable mounting, and wall mounting, with a maximum installation height of 5 meters and a covered passage width of 2–3.8 meters. It is widely used in archive management, access control systems, fixed asset tracking, and smart warehousing.
