TDE0160 Proximity Detectors Features Supply Voltage +4 to +36V Supply Current < 1.2mA Loss Resistance 5 to 50k Oscillator Frequency < 1MHz Output Transistors I = 20mA, VCE(sat) 1.1V ) s ( ct u d o SO14 r P e Description 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 with peak limiting. Hysteresis is adjustable, and an electronic switching circuit is incorporated for disabling both outputs.
