General description
The mini key MT0.1 (Minitaster MT0.1) produces an electric field
above his bonding surface. It penetrates glass, stone, plastics and
wood up to a thickness of 1 cm.
After POWER ON a self-balancing takes place in 2 seconds.
Afterwards all slow field changes by humiditiy, pollution and
temperature are compensated.
Just a quick tip with the finger generates an output signal
(momentary – key, toggle – on/off).
The MT0.1 is especially suited for battery-operated instruments to a
supply voltage of U
B
= +7 VDC with an operational current of less
than 5 µA.
Supply voltages up to +30 volt are possible at types with npn-
output, if with a multiplier (see chart below) the operational current
is still limited to about 1 mA.
