PROXIMITY DETECTORS

STMicroelectronics 

Features

■ 10mA Output Current

■ Oscillator Frequency 10MHz

■ Supply Voltage +4 to +35V

Description

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.
