TCA305 Datasheet, PDF (1/7 Pages) Siemens Semiconductor Group – Proximity Switch

Proximity Switch
Features
q Lower open-loop current consumption; IS < 1 mA
q Lower output saturation voltage
q The temperature dependence of the switching
distance is lower and compensation of the resonant
circuit TC (temperature coefficient) is easier
q The sensitivity is higher, so that larger switching
distances are possible and coils of a lower quality can
be used
q The switching hysteresis remains constant as regards
temperature, supply voltage and switching distance
q The TCA 305 even functions without external
integrating capacitor. With an external capacitor (or
with RC combination) good noise immunity can be
achieved
q The outputs are temporarily short-circuit proof (approx.
10 s to 1 min depending on package)
q The outputs are disabled when VS < approx. 4.5 V and
are enabled when the oscillator stabilizes
(from VS min = 5 V)
q Higher switching frequencies can be obtained
q Miniature package
