- 10mA Output Current
- Oscillator Frequency 10MHz
- Supply Voltage +4 to +35V
These monolithic integrated circuits are designed for metallic body detection by sensing variations in high frequency Eddy current losses. Using an externally-tuned circuit, they act as oscillators.
The output signal level is altered by an approaching metallic object.
The output signal is determined by supply current changes. Independent of supply voltage, this current is high or low, according to the presence or absence of a closely located metallic object
