STEVAL-IFS006V2 Smart inductive proximity switch with the SPT01-335DEE Data brief Features Metal body detection using the eddy current effect on the HF losses of a coil Flexibility MCU firmware can be modified based on application requirements sensitivity and hysteresis adjustment In-circuit programming and debugging capabilities Analog and digital temperature compensation PNP (high-side) sensor functionality configuration STEVAL-IFS006V2 Complete Transil protection of the output and power supply lines Overload and short-circuit protection Indicator status LED Compact design Supply voltage: 7 V to 32 V DC Temperature range: 25 C to +85 C RoHS compliant Description The STEVAL-IFS006V2 demonstration board is an inductive proximity switch application based on the principle of metal body detection using the eddy current effect on the HF losses of a coil. The design consists of a single transistor HF oscillator, an ST7LITEUS5 microcontroller, an intelligent TDE1708DFT power switch, and a SPT01-335DEE triple Transil array. The STEVAL-IFS006V2 represents a very simple, compact and cost-effective solution for an inductive proximity switch with wide temperature range, supply voltage variation and noise immunity in industrial environments.
