CM2000-4 RFID

1

Fast Pooling, 4 Antenna Ports

  • The fastest polling rate of each antenna reaches 25ms.
  • Different polling rates can be applied to different antennas.
  • 4 antenna ports provides a wider reading range

2

Best-in-class RF Chip

It employs Impinj Indy R2000 UHF RFID RF chip, which promises highly precise UHF RFID read/write in wide range and low-phase noise.

3

Powerful Data Capture Ability

  • Read tags with high stability and sensitivity
    Resistant to electromagnetic interference.
  • Support long-distance reading. The read range is 10 meters when using a 4dBi antenna
  • Ideal for high volume applications. The reading rate reaches over 400 tags per second with high accuracy.

4

Professional Temperature Controlling

  • The internal heat sink made of heat sensitive material delivers high heat conduction rate.
  • Enough ground plane heatsinking needs no external cooling sensors.
  • Built-in chip monitors the module temperature for the protection of the system.

5

Stable Performance Monitoring Capability
