UHF Passageway Door | UHF RFID Walk‑Through Portal Gate

DS902 UHF Passageway Door is a high‑performance walk‑through UHF RFID channel device with fully independent intellectual property rights. Built with a sturdy, deformation‑resistant metal frame, this portal reader complies with UHF EPC Gen2 (ISO18000‑6C) standard, delivering fast anti‑collision tag reading & writing performance.

It adopts infrared intelligent entry‑exit detection, capable of judging passing direction and realizing automatic people counting. Two core working modes are supported: inventory scanning and EAS detection‑alarm. Both true‑EAS and simulated‑EAS anti‑theft modes are available, together with user‑customizable alarm rules.

Rich hardware interfaces including RS232/485 serial ports and TCP/IP Ethernet allow direct connection to host PC, PLC and access controllers. Designed for high‑traffic open passage scenarios, it fits supermarkets, libraries, warehouses, attendance check‑in, conference sign‑in, logistics‑warehouse management and industrial process control, and works reliably under harsh industrial working environments.

Key Features & Product Advantages

1. Sturdy metal frame construction: Robust metal housing, anti‑deformation for long‑term heavy‑duty onsite deployment.
2. Full ISO18000‑6C / EPC Gen2 compatibility: Fast anti‑collision read‑write for standard UHF passive RFID tags.
3. Region‑adaptive adjustable frequency: 840‑960MHz working band; supports frequency hopping(FHSS) or fixed‑frequency transmission, can be tuned to meet local radio regulatory requirements worldwide.
4. Adjustable RF output power: Output power 0‑30 dBm, maximum up to 30 dBm, flexible to match site reading‑distance needs.
5. Infrared direction‑sensing & people‑counting: Built‑in infrared motion sensor, identifies inbound/outbound moving direction and counts pedestrian flow automatically.
6. Dual‑mode EAS anti‑theft alarm: Inventory reading mode + EAS detection‑alarm mode; supports true‑EAS and simulated‑EAS, alarm triggers fully customizable.
7. Audio‑visual local alert: Integrated buzzer plus red‑blue dual‑color LED indicator lights for clear on‑site warning notification.
8. Abundant industrial‑grade I/O interfaces: RS232 / RS485 serial, TCP/IP network port; 4‑channel switch signal input, 4‑channel high‑current output for automation system integration.
9. Low‑power hardware design: Optimized power consumption for continuous 24/7 operation.
10. High‑reliability industrial design: Meets strict requirements of demanding working conditions, stable performance for warehouse, retail and library high‑throughput passages.
