VDO SENSOR KITAS 2171-50 User manual

The intelligent KITAS sensors form a new generation
of speed sensors. With the innovative crypto-graphi-
cal IC the gear-box signals can be transmitted
tamper-proof without an armoured cable for the first
time.
A dynamic element converts the revolution of an
impulse- or gear wheel into electrical signals.
In parallel to the encrypted revolution data the
conventional real-time signal is also available.
Through a comparison of these two sources the
tachograph can detect data manipulations safely.
Therefore the KITAS sensor and the tachograph form
an authorised system.
A link between the serial numbers of the KITAS
sensor and the tachograph enchances the security
even further.
