4 Port UHF RFID Reader with Four TNC Antenna Ports
This 4 port RFID reader is designed for fixed UHF RFID systems that require multiple external antennas from one reader.
It provides four TNC antenna ports, RF output up to 33 dBm, and tag identification speed of more than 1,000 tags per second. Supported protocols include EPC C1G2 and ISO 18000-6B/C, with additional protocol options available for specific projects.
Ethernet, RS232, RS485, WiFi and Bluetooth provide multiple ways to connect the reader with RFID software and control systems.
Four Antenna Ports for Multiple Reading Zones
Four external RFID antennas can be connected to the same reader, allowing antenna positions to be arranged around different sides of a doorway, conveyor, production station or other fixed identification point.
Unlike an integrated reader with a built-in antenna, the external antenna design gives system integrators more flexibility over antenna type, mounting position and reading-zone layout.
The reader also supports RSSI, tag filtering and antenna status detection, helping with RFID system configuration and tag-data processing.

RFID Reader Functions
The reader supports several functions useful for multi-antenna RFID deployment:
- Dense reader operation
- Tag RSSI reporting
- Tag filtering
- Antenna status / standing-wave detection
- Online firmware upgrade
- Fixed-frequency and frequency-hopping operation
- External input and relay output control
These functions allow the reader to be configured for different identification zones without requiring every RFID event to be handled only by application software.
Typical Applications
- Warehouse & Logistics
Multiple antennas can be positioned around receiving points, loading areas or warehouse checkpoints to identify tagged pallets, cartons and assets. - Production & Manufacturing
Suitable for fixed RFID stations on production lines or material-transfer points where tags need to be identified automatically. - Asset & Equipment Tracking
External antenna positioning allows RFID reading zones to be adapted to equipment entrances, storage areas or controlled asset movement points. - Vehicle & Gate Management
Antennas can be positioned according to the lane or gate structure for UHF vehicle-tag identification.

Hot To Customize RFID Tags
Know the customization process for RFID tags
Size & Shape
Send your requirements on size and shapes. Tags are typically designed in simple shapes and sizes to match the internal antenna. However, they can also be customized in various sizes and shapes to best fit the intended application and the asset being tagged. For instance, RFID hang tags can be customized in size, shape, and attachment method to perfectly suit specific applications.
Layout & Chips
In the label format designer, select the layout that matches the type and size of the RFID label you wish to create. Our factory provides a variety of label templates, including RFID-specific options. We also offer a range of RFID chips tailored to meet your specific requirements.
