Excellent reading performance, Label identification is sensitive and stable.Stable recognition distance of 2-3 meters.(9662 standard Cr80 Card).  Multi-tag recognition performance: Greater than 50 labels. Label recognition speed: Greater than 50 sheets / sec. Solve the problem of heat completely  No external heat sink is required. Long-term continuous full-load operation at room temperature does not cause heat.  24 hours x 365 days of work does not crash. The performance is affected by external influences such as the outer casing and electromagnetic environment.  Wide temperature design, the temperature drift coefficient is extremely low. Excellent consistency  Installation method  Support 5pin WAFER installation.  Operating voltage DC 3.5V - 5 V  Standby current Less than 80ma (en high level)  Sleep state current Less than 100ua (en foot low level)  Operating current 180mA @ 3.5V (26 dBm Output, 25°C).  110mA @ 3.5V (18 dBm Output, 25°C).  Start time : 100ms.  Operating temperature - 20 °C - + 70 °C  Storage temperature - 20 °C - + 85 °C  Operating humidity Less than 95% ( + 25 °c) 95%=" (=" +=" 25="  Air Interface Protocol EPCglobal UHF Class 1 Gen 2 / ISO 18000-6C  Working spectrum range 840-960MHZ  Output power range 18-26 dBm  Output power accuracy +/- 1dB  Output power flatness +/- 0.2dB  Receive sensitivity Less than -70dbm  Inventory label peak speed Greater than 50 sheets / sec  Tag Cache 200 Labels @ 96 bit EPC  Label RSSI support  Communication interface TTL Uart interface  Communication baud rate 115200 bps (default and recommended)  38400bps  Cooling method Air cooling (no external heat sink required)  Material: PC+Metal  colour: As shown    Package Contents:  1 x Long Range UHF Integrated Reader Writer Module(865-868MHz)  /  1 x Long Range UHF Integrated Reader Writer Module(902-928MHz)z)    Only the above package content, other products are not included.  Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
