  • Page 9: Signal Transmission

    Signal Transmission The possible transmission distance is essentially determined by the highest occurring signal frequency, the properties of the transmission line and the input of the connected receiving device. When connected to our Isolating Barrier D461R1…, a signal frequency of 25000 Hz can be safely transmitted over a distance of up to 500 m.
  • Page 10: Direction Of Rotation Signal For Sensor Series A5S1Dd3 / A5S1Ds3 / A5S14 / A5S15 / A5S16

    Direction of rotation signal for sensor series A5S1DD3 / A5S1DS3 / A5S14 / A5S15 / A5S16 The sensor indicates the direction of rotation by a constant signal, which is either high or low depending on the direction (see below for level values). The change is instantaneous as soon as a pole pitch (e.g., 1 tooth) has passed the sensor.
  • Page 11: Level And Shape Of The Output Signal

    1.10 Level and shape of the output signal Rectangular pulses at low frequencies and with short lines. At higher frequencies and with long lines, the signal at the receiver becomes a saw tooth tread profile. Pulse pitch depends on the profile shape, when sampling a gear wheel profile, it is about 1:1. The level is the same over the entire speed range.

    Hazardous protection The safety requirements as determined by EN 1127-1, as well as the corresponding national regulations, are to be complied with regarding primary explosion protection, i.e. measures which prevent or restrict the formation of a hazardous explosive atmosphere. In the case of secondary hazardous protection, i.e. measures that prevent the ignition of an explosive atmosphere surrounding electrical equipment, the series of standards applicable to EN 60079 and the relevant national regulations must be observed.
