Data Brief
STEVAL-IFS006V1
Description
The STEVAL-IFS006V1 demonstration board is an inductive proximity switch design based on the principle of metal body detection using the effect of eddy currents on the HF losses of a coil.
It consists of a single transistor HF oscillator, the
ST7LITEUS5 microcontroller and the
TDE1708DFT intelligent power switch.
In addition to its simplicity, wide temperature range and supply voltage variation, the inductive proximity sensor design implemented in the STEVAL-IFS006V1 demonstration board is also compact and cost-effective.
