TAAO  (125Khz) RFID LF emitter antenna low frequency Features

Createmax provides a new low profile antenna. It is specially designed to assembly in the aftermarket operation. We design this antenna for emission of a LF field to allow hands free access towards the Customer Device Identification for automotive application.Antenna concept is similar to those CM-KGEA-TA series, but smaller in size (ferrite +capacitor in
a box potted) and easy to joint to anywhere by a simple adhesive tape.These kind of antennas provide a cable with a customized length without connector in its standard version (connector can be assembly under demand). It can be located outside the assembly of the antenna with 2 cables type CSA 105°C.Housing plastic base Polyamide enhanced (ABS optional) assuring extreme conditions of humidity, liquids, substance and extreme environments. Several combinations of inductance and capacitor values are offered as standard versions. Any other combination can be provided, together with the possibility
of fully customized design, depending mainly of capacitor size available.
