[micmad]

Can you help me with this ???

absolut rotary encoder 100.000RPM

position feedback: stand still ... 100.000RPM
resolution: 1 < Degrees < 6
output signal: parallel 7...8BIT ore SIN&COSINE
operation temp.: -25...>=+100°C

Boundary conditions:

high internal EMI magnetic up to 100mT
electric up to 100V/m, high BW

displacement of shaft
axial + - 200um
radial + - 100um

very limited space outside diameter < 70mm
inside diameter > 35mm
thickness ca. 10mm
including disk, airgap, sensor PCB

do you have an idea or clue ???

thanks

The measurement is not difficult (PLL) except
mech. accuracy is poor.

100 thousand rev/min is the max. What is the minimum ?
100 micron displacement seems to be excessive.

How much is the max. acceleration?

Could you tell me more about the application?
