Smart inductive proximity switch with SPT01-335DEE

1 Introduction

The STEVAL-IFS006V2 demonstration board shows an inductive proximity switch based on
the principle of metal body detection using the eddy current effect on the HF losses of
a coil. It consists of a single transistor HF oscillator, a ST7LITEUS5 microcontroller, an
intelligent TDE1708DFT power switch, and an SPT01-335DEE triple Transil array. The
board demonstrates a very simple compact and cost-effective solution of an inductive
proximity switch wit
