1.5.2 Spindle Side PLG Serial Output Encoder (TS5690, MU1606 Series)
(1) Part configuration
The encoder is configured of a sensor and detection gear. The sensor and detection gear must be used in the
designated combination.
These are precision parts, and require care when handling. Do not apply an excessive force on the sensor's
detection surface, as this could result in faults. Do not pull and apply a load on the lead wires. Make sure that
foreign matters (iron chips, etc.) do not get on the sensor's detection surface or detection gears. If any foreign
matter should get on these parts, carefully remove while taking care not to damage the parts. When handling the
detection gears, take care not to damage or deform the teeth.

(2) Installing the detection gears
[1] Install the detection gears so that the first gear's teeth side (Z phase) face the sensor's lead side.
[2] The detection gears and shaft or sleeve should be fixed with shrink fitting. Refer to the following table for the
shrink fitting values. The detection gears should be heated evenly between 120 and 150°C using an electric
furnace, etc.
Guideline for detection gear shrink fitting values
[3] Keep the run-out of the outer diameter, when the detection gears are installed on the shaft, to 0.02mm or less.
[4] To remove a detection gear fixed with shrink fitting, use the screw holes opened in the axial direction for pulling
(two M5 screw holes or two M8 screw holes), or push the end with a jig. Carry out this work carefully. Applying
excessive force when pulling out the gears could cause the inner diameter of the detection gears to deform.
[5] Before reusing detection gears which have been removed, always measure the inner diameter dimensions,
and carefully check that the inner diameter is not deformed, and that the sufficient tightening amount can be
secured. Do not reuse the detection gears if the inner diameter is deformed, or if any abnormality such as
damage to the teeth is found.
