Mobility is an important factor for the global economy
Sophisticated engine management and strict exhaust gas standards require increasingly individual sensor solutions, highly efficient motor controls for electrified auxilliary units and innovative technologies. We are at home in this market and offer you the appropriate solution for your project.
Speed sensors for powertrain applications
Our engineers understand optimal control means: higher efficiency, lower emissions and an increase in driving pleasure
In order to handle resources in a responsible way and to protect the environment, it is necessary to measure precisely, even at a low rotational speed, immediately when the engine of a vehicle has been started.
Detecting rotational speeds without loss enables optimal engine control resulting in improved driving characteristics and low emissions.
- Working range up to 3 mm
- Temperature range -40 °C to +160 °C
- Protection rating up to IP 69
- True power on
- Detection of direction
High-precision rotational speed sensor featuring detection of rotational direction for start / stop systems
Special application: An inductive high speed rotor position sensor (SPINpad sensor)
A combination of high accuracy and fast response time is required for rotor position sensors in the electric motors of hybrid or electric vehicles. This allows the control unit to drive the motor optimally, and leads to a reduction in energy consumption and an increased range of the vehicle.
Pressure sensors for powertrain applications
Last generation pressure sensors are absolutely solid and have excellent long-lived characteristics. They win by their modular-building-concept and can be integrated into customer systems easily
AB Elektronik offers a great number of innovative and robust solutions for measuring pressure in different media. Due to flexible configurations, our pressure sensor modules can easily be integrated into customer-specific systems.
Particularly powerful engines in trucks, work machines, and agriculture applications require permanent monitoring in different media. A great variety of different basic technologies enables us to optimally suit sensor features to the respective customer application.

Sensing of differential pressure and velocity head in high longterm stability
Motor power converter for electrically driven water pumps
The customer-specific control module is fully integrated into the electric motor and includes all components which are necessary for the control of an electronic motor. The inputs from the master control unit are transmitted via PWM, LIN or CAN to the microcontroller which calculates the speed and the necessary commutation of the electronic motor (block, trapezoidal or sine). With gate driver and power MOSFET the coils of the motor are energized. In this process the speed (with or without sensors), current, voltage and temperature are monitored and in case of an error reported back to the master control unit.
