Installing The Spindle End Plg - Mitsubishi MELDAS MDS-C1 Instruction Manual

1-4-3 Installing the spindle end PLG

(1) Environmental conditions
Environment
Ambient temperature Sensor section : -10°C to +80°C (With no freezing)
Atmosphere
(2) Part configuration
The detector is configured of an encoder (Sensor section and PCB section) and detection gears.
The encoder section can be separated with an intermediate connector, but a type with the same
serial No. must be used in combination. The serial No. is indicated on the intermediate connector of
the sensor section and the output connector of the PCB section.

Detection
gears
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.
(3) Installing the detection gears and sensor section
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 shrinkage fitting. Refer to the
following table for the shrinkage fitting values. The detection gears should be heated evenly
between 120 and 150°C using an electric furnace, etc.
