HIMA F7123 Digital Drive Sensors

F7123 digital outputs are available in a variety of formats. Unlike analogue sensors, where the output value is a value that varies continuously over the entire output range, digital sensors have only two output values, either “0” or “1”. A flick switch (touch switch) is one of the simplest examples of a digital sensor. When not pressed, a flick switch is usually an open circuit with infinite impedance, and when pressed, it becomes a short circuit with zero impedance.

F7123 When interfacing a digital sensor to a data capture device, it is important to consider a number of key factors that may affect the performance of the interface. As a result of technological advances, a wide variety of sophisticated digital sensors are available on the market, and today’s sensors are capable of generating a long series of switching state transitions. When using these sensors, the frequency characteristics of the output pulse train, and even the shape of the pulses, characterise the sensor’s measurements, thus making continuous measurements possible.

The F7123 classifies sensors according to the signal characteristics of the drive signal output from the sensor (there are five types), of which 45 % of digital sensors characterise the output in terms of the switching state of the digital line, 35 % in terms of the frequency of the output signal, 12 % in terms of the duty cycle of the output signal, another 6 % in terms of the time interval and 2 % in terms of the number of pulses.
