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. The built-in output stage can pull loads to
zero and to operating voltage equally strong.
The signal level during no-load running is almost equal to the supply voltage. The diagrams
show how it gets smaller when the current load increases (the high-level decreases, the low
level becomes higher). If the permissible maximum load of 25 mA is exceeded, the level drops
sharply. The sensor is not damaged, the output is short-circuit proof.
The maximum load corresponds to a load resistance of 1000 ohms at 24 V supply voltage, 500
ohms are permissible with 12 V supply voltage.
