The intelligent KITAS sensors form a new generationof speed sensors. With the innovative crypto-graphi-cal IC the gear-box signals can be transmittedtamper-proof without an armoured cable for the firsttime.A statically operated hall-effect IC is utilised as thesensor. This element converts the revolution of animpulse- or gearwheel into electrical signals.In parallel to the encrypted revolution data theconventional real-time signal is also available.Through a comparison of these two sources thetachograph can detect data manipulations safely.Therefore the KITAS sensor and the tachograph forman authorised system.A link between the serial numbers of the KITASsensor and the tachograph enchances the securityeven further.Harness flexibility will be increased by using theintelligent KITAS sensor.Features• Conform with Regulation VO (EG) No. 1360/2002• Certificate through BSI according to ITSEC,level E 3 High, as per supplement 1B• Full fills the Generic Security Target’s as persupplement 1B• Integrated in the gearbox• Data security by cryptological procedure(TRIPLES DES)• Non-contact measuring system (Hall IC)• Sealing possibility• Replace the steel armoured cable• Interface according to ISO 16844-3• Standard plug according to ISO 15170• Comparison of the real-time signal with theencoded signal• Power-On reset function• Storage of additional facts (identification,installation)Use• Only for use in the new tachograph generationMTCO 1324 (Modular Tachograph) andDTCO 1381 (Digital Tachograph)www.vdo.comSensorKITAS 2171-20
