Product Descriptions
Long Range Fixed UHF RFID Readers Writer
The N204 long distance UHF RFID Reader is built for harsh environments like dusty factories, wet warehouses, or oily production lines. Designed with anti-vibration technology and a sealed structure, it withstands shocks, heavy dust, moisture, and oil while reading tags up to 20 meters away.
This rugged device combines high durability with long-range accuracy, making it ideal for asset tracking, inventory management systems, and supply chain management in demanding industrial settings. Whether monitoring machinery in chaotic workshops or managing stock in challenging conditions, the N204 ensures reliable data capture and seamless integration with industrial workflows.
Advanced Anti-collision Technology
with a four-port design that lets you connect four antennas at the same time without signal problems, the N204 long distance uhf rfid reader writer is perfect for places with many items to track, like busy warehouses, large retail stores, or fast-moving production lines.
The advanced anti-collision technology helps read hundreds of tags quickly and accurately. Even when boxes, tools, or products are packed closely together, the rfid tag reader avoids mixing up signals. For example, in a logistics center scanning pallets on a conveyor belt, it reads every tag correctly without delays.
Where to Use These Readers
These long distance uhf rfid tag readers work well in busy environments. For example, they help track boxes and machines in warehouses or during production. RFID scanners also check stock quickly in retail stores or libraries. In parking areas, RFID reader writers monitor cars or high-value items like jewelry. For factories or library shelves, they improve asset tracking and reduce errors.
From supply chain management in manufacturing plants to stock management in busy stores, our rfid tag readers simplify operations. They help libraries track books faster, protect jewelry in shops. The technology also supports inventory tracking systems for asset tracking in large warehouses or busy factories.
N204 industrial fixed uhf rfid readers connect easily to existing inventory systems and supply chain management software. They read hundreds of tags at once (1000 tags in 2 sec), even in moving production lines or logistics hubs. This reduces errors in stock management and improves speed for retail businesses, library staff, or manufacturing teams.
Seamless Connectivity for Smart Operations
The N204 supports Ethernet, HDMI, RS-232, and RS-485 interfaces, along with built-in dual-band Wi-Fi (2.4G/5G) and Bluetooth, ensuring fast, stable data transfer in industrial environments. It works with TCP/IP, HTTP, SSH, Telnet, and mDNS network protocols, enabling flexible networking for warehouse tracking, production line monitoring, or logistics center updates.
Performance for Weak Signals and Interference
N204 uhf rfid tag readers can pick up weak signals from tags up to 15 meters away. Its RF power out achieves 33dBm, which can detect even very quiet signals, helping track small items or tags hidden behind boxes in warehouses.
These long distance uhf rfid readers work well near metal objects, wet places, or areas with radio noise (like WiFi). They automatically adjust their signals using smart frequency switching (FHSS) to avoid problems. For example, in a metal workshop or a cold storage room with water, they still read tags correctly 99% of the time.
RFID Tag Compatibility
Passive tags (no battery): Perfect for tracking boxes in warehouses or clothes in stores.
Active tags (with battery): Used to monitor valuable items like medical tools in hospitals over long distances.
Semi-passive tags (small battery): Best for cold storage or medical supplies where temperature tracking is needed. The battery helps sensors work longer without extra power.
Durability for Tough Conditions - IP55 Protection Rate
N204 industrial fixed uhf rfid writers have a strong metal and plastic case that survives drops up to 1.5 meters onto concrete floors. The RFID scanners are rated IP55 waterproof and dustproof, meaning they work in heavy rain, dusty workshops, or freezing warehouses. The sealed design keeps water out even when used near washing stations or outdoor parking areas.
What Frequency Band Our Readers Use
N204 industrial uhf RFID readers support all major frequency bands required by law, including the FCC 902-928MHz range for the US, ETSI 865.6-867.6MHz for Europe, and SRRC-MII 920-925MHz for China. If your country has special frequency rules – like Japan’s 920MHz band or Brazil’s 915MHz range – we can adjust the frequency settings to match your needs.
