Description

The CHAFON CF811 fixed reader utilizes UHF RFID technology compliant with the ISO18000-6C (EPC Gen2) protocol, employing an advanced anti-collision algorithm for efficient simultaneous tag identification. Its robust signal conditioning and adjustable RF power allow for optimized performance across varying environmental conditions and tag densities.

Engineered for continuous operation, the reader features a 12V DC power supply with a current draw of 500–1200 mA and includes 2 GPI and 2 GPO ports for external device control and event triggering. The die-cast aluminum enclosure provides electromagnetic shielding and physical protection, ensuring durability in warehouses, logistics hubs, and smart inventory cabinets.

Key Features

  • High-density tag reading with a throughput of 200 tags/sec minimizes system latency.
  • Eight independent RF channels via SMA connectors support expansive antenna arrays.
  • Software-adjustable RF power output (0–33 dBm) enables fine-tuned read zone definition.
  • Comprehensive communication interfaces: USB (for configuration), RS232/RS485 (for industrial PLCs), and Ethernet TCP/IP.
  • Integrated GPIO (2x Input, 2x Output) allows for hardware triggers and peripheral integration.
  • Rugged, IP55-rated die-cast aluminum housing resists dust and water spray.
  • Includes a full Software Development Kit (SDK) with APIs for C#, Java, Python, and VB.NET.
  • Supports global UHF frequency bands (865–868 MHz for EU, 902–928 MHz for US).

Applications

  • High-speed warehouse inventory management and pallet tracking systems.
  • Industrial asset tracking on production lines and in tool cribs.
  • Smart laundry and textile management for uniform identification.
  • Library and document tracking systems requiring bulk item processing.
  • Logistics and supply chain visibility platforms for container and parcel monitoring.

Frequently Asked Questions

What communication interfaces does the CF811 RFID reader support?

The CF811 provides multiple standard interfaces for flexible integration: USB for direct PC connection and configuration, RS232 and RS485 for serial communication with PLCs and industrial controllers, and Ethernet TCP/IP for network connectivity. Optional modules for Power over Ethernet (PoE) and WiFi are also available.

How do I adjust the read range and power output of the reader?

The read range is controlled via the software-adjustable RF output power, which can be set from 0 to 33 dBm. This is configured through the provided management software or SDK API commands, allowing you to optimize performance for specific tag densities and environmental conditions to achieve the desired 0–15 meter range.

What software tools are available for developing with the CF811?

CHAFON provides a comprehensive Software Development Kit (SDK) including dynamic link libraries (DLLs), API documentation, and sample code for popular programming languages such as C#, Java, Python, and VB.NET. This enables developers to build custom applications for inventory management, asset tracking, and data logging.

What is the power requirement for the CF811 reader?

The reader requires a 12V DC, 2A power supply for normal operation, with a typical current draw between 500 mA and 1200 mA depending on RF output power and connected antenna load. The unit includes GPIO pins but does not supply power to antennas; each antenna requires its own separate power source.
