Infineon simplifies speed sensor design with TLE4922 sensor and "Speed ​​Sensor 2Go" kit

Sensor development kits from Infineon will significantly reduce design effort, resulting in shorter development times and lower system costs. Industrial applications include speed detection for production and building automation and electric drive control devices.

TLE4922 ensures reliable speed measurement and reduces system cost

The TLE4922 Hall sensor reliably measures changes in the magnetic field. This means it can be used for speed detection of many types of wheels, such as magnetic encoder wheels or ferromagnetic gears. In addition to a wide range of applications, the TLE4922 also helps reduce system costs. For example, it supports the use of simple and cost-effective back magnets while achieving high air gap performance and phase accuracy. The sensor is also very robust against vibration and air gap jumps, enabling accurate speed detection over a wide magnetic field range of +/- 400 mT.

The TLE4922 is especially suitable for TIM (Twist Standalone Installation) configurations. Therefore, it can replace the passive speed sensor in the motor and on the two-wheeler and car wheels. Compared to passive speed sensors, the TLE4922 accurately measures speeds starting at 0 Hz. In addition, it has good jitter performance and provides many protection features to prevent short circuit, overheat and reverse voltage. Good electromagnetic compatibility (EMC) and ESD robustness make it suitable for use in harsh working environments. It operates from 4.5 V to 18 V and operates over the -40 ° C to 155 ° C temperature range. The sensor is available in a 4-lead SSO package.

Easy sensor design with the SpeedSensor 2Go kit

The initial measurement can be completed in just a few minutes. The Speed ​​Sensor 2Go kit includes sensor modules, interface boards, and cables. The sensor module integrates the TLE4922 sensor with a ferrite magnet. The interface board has two XMC microcontrollers: one for triggering and one for debugging. The USB cable provided in the kit can be used for PC connection. A graphical user interface (GUI) based assessment tool records and graphically displays speed data. In addition to the "Speed ​​Sensor 2Go" kit, Infineon offers additional software-enabled development tools that support sensor simulation, such as System C models or special evaluation tools.
