VDO SENSOR KITAS 2171-20 - DATASHEE 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 statically operated hall-effect IC is utilised as the 

sensor. This element converts the revolution of an 

impulse- or gearwheel 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.

Harness flexibility will be increased by using the  

intelligent KITAS sensor.
