Display legible at any light conditions
Outstanding legibility in every environment and a high reliability even in harsh conditions are main advantages of electromagnetic displays. A big advantage is, that an outstanding legibility is retained even at direct sunlight.
Unlike LED or LCD displays, electromagnetic displays have every segment of a
digit controlled by electromagnets, by means of two coils - set / reset.
Principle is similar to a bi-stable relay, thus for activation/ deactivation is
necessary only a pulse 12V/ 350 mA lasting 90-150 ms according to a type of
display. This also means, that the display has a zero power consumption at rest,
e.g. power is necessary only for a change of status in a form of a short impuls.
They are available in sizes from 10 to 58 cm, with white or yellow segments
and a black background and in 2 versions: without or with a rear-mounted circuit
board including connectors for easy attachment of ribbon cable and power wires.
They are suitable to display for exampple these parameters: currency or a price
(petrol signage), scoreboads – time/ speed, weight at industrial scales, motel
rooms prices, time and temperature, various industrial measures and many other.
