描述 Description

The device TCA355G contains all the functions necessary to design an inductive proximity switch. By approaching a standard metal plate to the coil, the resonant circuit is damped and the outputs are switched.

特性 Features

• Low openloop current consumption; Is < 1 mA

• Low output saturation voltage

• Low temperature dependence of the switching distance and compensation of the resonant circuit temperature coefficient

• High sensitivity, so that larger switching distances are possible and coils of a lower quality can be used

• Constant switching hysteresis over temperature, supply voltage and switching distance

• The outputs are temporarily shortcircuit 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)

• High switching frequencies can be obtained

优势:

应用 Application

• Proximity Switches
