In automated boxes with electronic control, switching does not come down to the operation of one or another electromagnetic clutch in the planetary mechanism, but occurs, as in ordinary "mechanics", by moving the gears themselves.
It is quite obvious that the controlling controller needs to know exactly at each moment of time where this or that gear is fixed or where it is moving. Such information is collected by numerous sensors developed by Tiko Electronics.
Very strict requirements are imposed on these sensors both in terms of temperature conditions (range not less than -40 … + 140 ° C), and in terms of vibration resistance, accuracy and resistance to aggressive media. It is advisable that the sensors are eternal and do not wear out. The latter is possible only when using the contactless principle, and it is better to do without capricious and unstable semiconductors.
