Product features


Brief introduction

◆ Integrated antenna character

1. Be sensitive and stable to the tags identify.

2. Stable reading distance 2-3 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<200mA @ 3.5V (26 dBm Output). Pulse peak current<260mA。

◆ 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: support 5pin WAFER installation.
