Procedure Place target at the desired sensing
distance. Set sensitivity adjuster to the
minimum scale position, and gradually
increase sensitivity by turning the
sensitivity adjuster clockwise until the
Light Incident indicator (red LED)
turns ON. Position A designates the
point at which the LED has turned ON.
Remove the target. Starting from the
maximum scale position, gradually
decrease sensitivity by turning the
sensitivity adjuster counterclockwise
until the Light Incident indicator (red
LED) turns OFF. Position B
designates the point at which the LED
has turned OFF.
Set the sensitivity indicator to the
position between Positions A and B (in
some cases, Positions A and B are
opposite of the above example). To
insure stable sensor operation, the
green stability indicator should be fully
“on” in both the sensing and
non-sensing conditions.

Precautions
WARNING
These photoelectric sensors should not be used in personal
safety applications. Using the sensor as a safety device may
cause an unsafe condition that could lead to serious injury or
death.
CAUTION
Cover Screw Torque:
The torque of the cover screw must not exceed 3.5 kgScm
(3 inSlb). Over-torquing twill cause the plastic parts to crack.
JHIGH-VOLTAGE LINES
Do not place sensor power supply or signal lines within the same
conduit as high-voltage power lines.
JVOLTAGE RATINGS
Do not exceed rated supply voltage, ripple percent (for DC
models), or load current limits.
JAMBIENT LIGHTING
Do not install sensor in direct sunlight, or other sources of strong
ambient light.
JENVIRONMENTAL CONDITIONS
Do NOT install sensor in areas that have any of these conditions:
#High humidity, or where condensation would result.
#Corrosive gas.
#High vibration or shock.
JPOWER SUPPLY
If a switching power supply is used, or when using with an
inverter or servomotor, ground the FG (frame ground) and
G (ground) terminals on the power supply for proper operation to
avoid damaging the sensor.
JWATER EXPOSURE
Do not use the sensor where it may be immersed, is outdoors, or
exposed to rain.
JPROPER MOUNTING SCREWS
Use M5 screws and washers to mount sensor and bracket.
JMECHANICAL SHOCK
Avoid mechanical shock during installation which may damage
the housing.
JCONNECTOR
#When connecting or disconnecting the connector, hold the
connector cover to avoid tension on housing.
#Tighten connector only by hand. Do not use tools, which may
damage the connector.
#Always disconnect power before connecting or disconnecting
the connector.
#Be sure that the connector is tightened securely. If this is not
done, the sensor enclosure rating may be reduced, or the
connector may loosen and affect the enclosure rating.
