Power Supply
The Gallagher T10 Mifare reader receives power from the device to which
it is connected. The reader is designed to operate over a supply voltage
range of 9 - 16Vdc measured at the reader terminals. The operating
current will be approximately 40mA (at 16Vdc) and 70mA (at 9Vdc).
The operating current will increase to approximately 120mA (at 12Vdc)
momentarily during a card read, beeper and LED activity.
The power source should be linear or a good quality switched-mode power
supply. The performance of the reader may be affected by a low quality,
noisy power supply.
Cabling
The Gallagher T10 Mifare reader requires a minimum cable size of 4
core 24 AWG (0.2mm
2
) stranded security cable. This cable allows the
transmission of data (2 wires) and power (2 wires). When using a single
cable to carry both power supply and data, both the power supply voltage
drop and data requirements must be considered. For good engineering
design, it is recommended that the voltage at the reader should be
approximately 12Vdc.
The critical specifications for the cable are:
Data:
The capacitance between any two wires or between
a wire and any shielding should be less than 24nF
Power supply: The voltage at the reader must be at least 9Vdc

reader to a Controller and power supply, showing maximum cable lengths
