This RFID device reads the popular RFID tags running in the 125 kHz band (Manchester coding). Each tag has its own unique identification number, which is sent through 1-wire® bus by emulating a DS1990A iButton®. Features Reads RFID tags running in the 125 kHz band Data are sent by emulating a DS1990 iButton® Plastic casing Designed to be mounted with glue Side entry of the flat wire Standard wire ~40 cm No series resistor required, simply connect LED anode to the plus, e.g. the power supply (** please check notes below) ** CautionIn case of connecting anode to the supply higher than 5V it is advisable to use an external resistor preventing from exceeding the maximum current suitable for LED. Applications Cash registers Vehicle/Driver ID Time and attendance Access control Pinouts Red Power supply (6.5-30 volts DC) Black Ground White 1-Wire Data Green Cathode LED Specification Power supply 6.5-30 V DC Active Current 12 mA (without LED) Frequency 125 kHz Reading distance ~4 cm LED Red Active Current LED 10mA
