Measurement Example
Power supply voltage: 5 VDC
Load resistance: 1 kΩ (Output residual voltage is measured
at a 35 mA load current.)
Cable: Special Cable
• This graph shows the relationship between mechanical life and
the load applied to the shaft.
• The size of the load during rotation affects the life of the bearings.
• This graph shows the effect of the output waveform if the cable is extended.
• Extending the cable length not only changes the startup time, but
also increases the output residual voltage.
