TCA355G

接近开关 Proximity Switch

Features

● Lower open-loop current consumption; IS < 1 mA

● Lower output saturation voltage

● The temperature dependence of the switching distance is lower and compensation of the resonant circuit TC temperature coefficient is easier

● The sensitivity is higher, so that larger switching distances are possible and coils of a lower quality can be used

● The switching hysteresis remains constant as regards temperature, supply voltage and switching distance

● The TCA 305 even functions without external integrating capacitor. With an external capacitor or with RC combination good noise immunity can be achieved

● The outputs are temporarily short-circuit proof approx. 10 s to 1 min depending on package

● The outputs are disabled when VS < approx. 4.5 V and are enabled when the oscillator stabilizes from VS min = 5 V

● Higher switching frequencies can be obtained

● Miniature package
