Mini Uhf Rfid Reader
mini uhf rfid reader
Brief introduction
Integrated antenna character
1. Be sensitive and stable to the tags identify.
2. Stable reading distance 6-7 meters.
3. Multi-tags identify, >50pcs tags.
4. Reading distance speed, >50pcs/sec.
Solve the exothermic problem completely.
1. No need for connecting any other outer radiating device. It can work without exothermic reaction in the normal indoor temperature.
2. Sustain electricity<800mA @ 3.5V (30 dBm Output). Pulse peak current<1200mA.
Outstanding stability:
1. 24 hours x 365days work normally.
2. Appearance little influenced by cover, electromagnetic environment etc.
3. Wide temperature design and the temperature drift coefficient.
Good consistency:
1. The good design in consistency.
2. Choose the top level components to keep each parameters stable and consistence.
Brief and high efficient interface of hardware and software.
- 1. Peripheral circuit is very easy. The signal power, no need for extra connecting tantalum capacitor.
Installation method: support5pin WAFER installation.
