Precautions
Refer to the Technical Information Section for general
precautions.
The sensing window is made of a polycarbonate resin which
withstands alcohol, chloride solvents, and strong acids but is
soluble in strong alkali, aromatic hydrocarbons, and aliphatic
hydrocarbonate chloride solvents.
The casing material uses a PBT resin, which is soluble in strong
acid or alkali solvents.


Use the special screwdriver (included with sensor) for sensitivity
adjustment.
The sensitivity adjuster can be turned clockwise and
counterclockwise endlessly. This means when the sensitivity of
the photomicrosensor is maximum, further turning the adjuster
clockwise will abruptly drop the sensitivity to minimum. When
using the photomicrosensor with its maximum sensitivity, pay due
attention to the adjustment of the sensitivity.
Sensitivity Adjustment with Background Object
1. Set the sensitivity of the photomicrosensor to minimum, place
2. Remove the sensing object. When the operation indicator is
EE-SY671/672
the sensing object at the sensing position, turn the sensitivity
adjuster clockwise slowly until the operation indicator is lit
(point A).
OFF, further turn the sensitivity adjuster clockwise slowly until
the operation indicator is lit again (point B). The operation
indicator will not light again if the background object does not
reflect light, in which case refer to Sensitivity Adjustment with
No Background Object.

The shaft of the sensitivity adjuster is charged. Connect a DC
power supply incorporating an insulated transformer to the
photomicrosensor. Do not connect a DC power supply
incorporating an autotransformer or the user may receive an
electric shock when adjusting the sensitivity.

points A and B. Points A and B will be very close if the sen-
sor is influenced by excessive light reflected by the back-
ground object. If this is true, take the following preventative
measures:
Make a large enough distance between the sensor and the
background object.
Cover the surface of the background object with a material
with a small reflection factor, such as a black sponge.

the sensing position. It should be off when the target is re-
moved.
