7.9.2 Technical characteristics of the Lenord+Bauer sine
encoder
A voltage level higher than the one specified (5V ±5%) may damage the encoder
reader.
CHARACTERISTICS VALUE
Rated power supply "U" 5V DC +/- 5%
Operating temperature -30° C ÷ 85° C (-22° F ÷ 185° F)
Max. operating altitude 2000m (6500ft)
Signal input (pulses per rotation) Depending on the model (refer to the Technical Datasheet)
A/B signal output
500 mV peak-to-peak with average value “U ref.”=U/2
1V peak-to-peak as difference of signals with average
value “U ref.” (see figures below)
A/B signal phase displacement 90° (a quarter period)
Z signal output
500 mV peak compared with idle value U ref. ±80mV
1V peak as difference of signals with idle value
U ref.-160mV= 2.34V (see figures below)
Key to the figures below
T Period (360° electric)
D Phase displacement (D=T/4)
A diff (A) - (A-)
B diff (B) - (B-)
Z diff (Z) - (Z-)
