Electronic Hand Throttles
The electronic hand throttle is a direct communications interface with the driver. An integrated sensor continuously indicates the position of the electronic throttle grip, and this information is transferred from the sensor to the control unit very quickly and accurately. The control unit communicates with an actuator at the throttle flap, which will open or close according to the sensor signal. A complex process chain follows that will influence engine management.
In addition to ensuring engine efficiency, several features are provided for safety and comfort, and these are driven by signals from the very same sensor in the hand throttle. The complexity of these processes creates a need for technologies that are precisely designed to the individual needs of each customer application.
Constant improvement of technologies supports additional features
Electronic hand throttles have largely replaced mechanical modules with Bowden cables. Controlling the powertrain with an electronic solution is much more precise, and therefore invaluable in meeting proposed exhaust emission standards, as well as providing additional features such as signals for regenerative braking in E-bikes.
Position sensors are integrated into the latest generation of electronic hand throttles, which convert the angle of the rotary handle into an electronic signal. This way, the signal can be sent directly to the control unit without loss. The sensors used in KYOCERA AVX electronic hand throttles deploy contactless ‘Hall effect’ technology. The signals are transferred very rapidly, with stability and high accuracy, fully satisfying the requirements of cutting edge vehicles. The EMC immunity and signal quality meet the highest standards in our customers’ premium applications, and allow very efficient individual customer designs.

Rotor Position Sensor – Electric Motors
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.
KYOCERA AVX 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 KYOCERA AVX‘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
- Traction Motors for any application (e.g. BEV, PHEV, HEV and MHEV or industrial applications)
- Electric Compressor
- Steer by Wire
- Electric Turbocharger/Supercharger

Pressure Sensors
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 - KYOCERA AVX. 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.
KYOCERA AVX’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 KYOCERA AVX.
Last generation pressure sensors are absolutely solid and have excellent long-live characteristics. They win by their modular-building-concept and can easily be integrated into customer systems.
KYOCERA AVX 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 the requirements in high-performance gearbox applications necessitate permanent monitoring of different media. Cost-optimized solutions with high vibration resistance are in great demand and a wide range of basic technologies enables us to optimally adjust the sensor characteristics to the respective customer application.
