Anyone recognize this tach system?
Anyone recognize this tach system?
(OP)
I'm unfamiliar with this 2000 era speed detection method. There are no marks on the edge of the disk. What you see in these pictures is just dust marks. We can discover NO magnetic attraction around the edge. Looking at the device on the green circuit board shows nothing really. It doesn't appear to penetrate the board.
Anyone know?

what is the motor part number?
Since you cannot detect any magnetic field, it may be inductive or capacitive sensor...
One pix seems to show like 1000 lines around the disk.... both Siemens and Indramat used inductive sensors to see 'teeth' on the rotating wheel....
