Proximity Sensor Inductive NPN 5V to 30V 8-Pin DSO

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.

• 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
• Pb-free lead plating; RoHS compliant
