AB Elektronik has a broad technology portfolio and close links with the semiconductor industry. We stay close to selected research centres, and ensure we stay right ‘on the pulse’ to meet the dynamic requirements of the market.

We equip our products with efficient, energy saving technology, and supplement micro power ICs or even passive components for wake-up functions with special power consumption requirements. Using innovative manufacturing processes, we produce robust, but slim and lightweight solutions with weight-optimized design. We identify the right package for your current requirements, and act as your well informed consultant for future applications.

Recuperation - Brake pedal travel

Position sensors on the brake pedals enable fast and accurate detection of the braking intention. A light application of the brake decelerates the vehicle by generating charging current via the driveline instead of activating the mechanical brakes. This extends the vehicle range and protects the environment.

  • Linearity: +/-1% 
  • Sealing: IP6K9K
  • Output signals: Analog, PWM, PSI5, Sent
  • Temperature range: -40 °C to + 80 °C

Battery condition

Mechanical condition monitoring of the battery cells: Depending on the type deployed (prismatic, cylindrical, cushion), battery cells are subject to different deformations during charging and discharging cycles. Our inductive approach to battery monitoring provides non-contact reliable information about the current state of deformation, and serves as a reference for battery ageing.


  • Air gap Measurement: 4-10 mm range     
  • Resolution: 10 - 12 Bit
  • ASIL: B(D)

Vehicle level

Modern vehicles perceive their environment independently via camera and radar systems. The fast and precise comparison of this information with the actual condition of the vehicle reveals any need for action for a safe and comfortable journey. Our position sensors in a weight-optimized design continuously detect the chassis position, and provide the necessary information for assistance systems. This is indispensable, especially for autonomous driving.

Pressure sensors

Pressure Sensors for Hybrid Electric Vehicles

New sealing concept offers high levels of safety and long term stability

A special pressure sensor designed for use at the fuel tank of hybrid-electric vehicles is the latest development from the specialists for ceramic pressure measuring cells - AB Elektronik Sachsen GmbH. The new pressure sensor features very high measuring accuracy over its life time, and satisfies the specific and demanding requirements of modern hybrid-electric vehicles particularly closely.

At the core of the new pressure sensor is a fully ceramic pressure measuring cell with integrated pressure connection. The sensor is mounted in a compact two-part housing. Next to the pressure measuring cell are the circuit board for signal conditioning and the electrical connection. Sealing against the installation point can be made with either one or two O-rings, depending on the medium and tightness requirements. Different O-ring materials can also be combined to allow compatibility with different media or aggregate states at the same time. Thanks to its optimal use of space, this new pressure sensor is only slightly taller than a MEMS pressure sensor for a comparable pressure range.

AB Elektronik’s in-house ceramic processing capability has enabled a rapid and flexible design of the pressure connection in terms of diameter and sealing concept, for individual adaptation to customer requirements. The preferably digital interface can also be quickly varied in its design.

"This new sensor opens up a very wide field of applications in the sophisticated low pressure range for sensors of this type" says Frank Rothe, specialist for pressure, temperature and liquid quality sensors at AB Elektronik Sachsen GmbH.

Motor Position Sensor

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.


AB Elektronik has developed a new high speed position sensor to meet these requirements. First prototypes of this new sensor have demonstrated market leading performance. This technology can be used in other applications where accuracy and response times are critical (for example, electric power steering), and is also capable of making an additional velocity measurement, which could be used in active suspension systems.


The basic structure of the SPINpad sensor is similar to AB Elektronik‘s mature and proven Autopad® technology. However, the SPINpad sensor uses one coil as a transmit coil and two coils as receive coils.


Typical applications

  • High speed accurate sensing of the rotor position in electric and hybrid vehicles motors
  • Electric Power Steering
  • Electric Motor traction drive
  • Active suspension systems

Special features

  • Flexible designs, can be matched to motor pole-pairs giving positional accuracy < 0.5deg electrical
  • Different targets available
  • Signal immediately after power on
  • High speed up to 100,000 rpm
  • Ready for ASIL C (D) or with redundant measurement ASIL D (D)
  • Immune to low frequency magnetic fields
  • Small package size, flat design
  • Temperature range: -40 °C to 160 °C
