The TDE0160 is designed to detect metal bodies by the effect of Eddy currents on the HF losses of a coil. It has two complementary open collector outputs withpeak limiting. Hysteresis is adjustable, and an electronic switching circuit is incorporated for disabling both outputs.
An internal zener diode maintains the supply voltage to the circuit in ”dipole” operation.
