12 VDC:
20 AWG, 500 ft. maximum, reader powered by
LNL-1340-M2K; 18 AWG, 3000 ft. maximum, reader powered locally
The above specifications are based on the typical 12 volt reader drawing 125 mA. Reader power
requirements vary between different models.
Note: Excessive voltage drop on long cable runs may require a larger cable gauge or powering the
reader from a local power source. Refer to the power specification for the reader being
installed.
