Sargas Specifications

The following are the specifications for the Sargas Reader.

UHF RFID Antenna Interface

Interface

: Two RP-SMA Connectors

RF Power Output

: Separate read and write levels, adjustable from 0 dBm to 30.0 dBm* 

(1.0 W) 

Frequency

: Hop table with up to 62 entries, configurable in 50KHz steps, accommodating 

the following ranges (hardware dependant): 

–  902-928 MHz (FCC; NA, SA) 

–  865.6-867.6 MHz (ETSI; EU) 

–  865-867 MHz (MCIT; India)

Power

External DC Power

: 5 VDC +/- 0.25V supply voltage. Maximum DC power: 15 W

Note

If a third-party DC Power supply is used it must meet the following criteria:
- Be UL Listed
- Meet the above operating specs
- The output must comply with SELV and LPS characteristics
- Have a maximum operating ambient temperature that meets or exceeds the 
intended Sargas operating temperatures as covered under the UL Listing of the 
power supply.

Environmental

Operating Temperature

: -40°C to +60°C 

Note

If an external DC power supply with a lower operating ambient temperature, as 
covered under the UL Listing of the power supply, is used then the operating 
ambient temperature of the Sargas would be reduced accordingly.

Storage Temperature

: -40°C to +85°C
