[. . . ] With the innovative crypto-graphical IC the gear-box signals can be transmitted tamper-proof without an armoured cable for the first time. [. . . ] With the innovative crypto-graphical IC the gear-box signals can be transmitted tamper-proof without an armoured cable for the first time. 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. 70 - 30 % unearthed rectangular 1 Hz - 1000 Hz Real-time signal UL max = 800 mV (@I = 250 A) UH min = UE - 1, 5 V (@I = - 150 A) Output short-circuit Output signal Pin 4 Protection against voltage interference Interference protection Protection Resistance to vibration Connection of sensor to sensor lead Connection of sensor to vehicle gearbox Torque (wrench size) Dimensions (L in mm) Weight approx.
