(13.5%) of the central intensity at the measurement center distance. Measurement may be influenced if there
is light leakage outside the defined region and the surroundings of the target object have a high reflectance in comparison to the target
object. Correct measured values may not be obtained if a workpiece with smaller diameter than the spot size is detected.
*
2. It shows the error in relation to the ideal curve of the displacement output when measuring OMRON's standard physical object (white
ceramic) under the environment at 25°C.
*
3. Temperature characteristics at the center of sensing distance when the space between the sensor and workpiece is locked with aluminum jig.
*
4. Static definition with the background suppression function ON for tuning with STND mode and standard white ceramic.
*
5. Connector-joint model cable: Use it together with a 10 m or 20 m extension cable.
*
6. The connector joint model connector section can achieve IP67 if it is connected via an extension cable.

Is LD OFF input not
short-circuited?
Individual wires may not be
correctly connected; or there
may be a broken line.
Temperature characteristic
may be the cause.
Is the detection distance
not too long and out of the
measurement range?
Is the emitter surface not
blocked by dust, dirt or a jig?
There may be mutual
interference with other
sensors.
A characteristic phenomenon
that can sometimes occur with
sensors.
Check the Sensor
installation environment.
Check the installation environment
and take measures to prevent the
interference by other sensors
such as laser beam path or
reflected stray lights.
Check the measurement distance
between the target object and the Sensor.
Reset the settings.
Is the power supply ON?
Are the cables not broken?
Is the Eco function not
turned ON?
Turn OFF the Eco function.
Check the wiring, the power
supply voltage and capacity.
Check the wiring.
Perform warming up at least
for 30 minutes. Periodically
zero-reset the value using
a standard target object
for compensation.
Cause
Remedy
Set the Background Suppression
function to: [ ] = [ ] and
perform smart tuning.
Check the wiring.
The Keep function may be set:
[ ] = [ ], and reception light
level may be insufficient:
[ ] or the value may be outside
the measurement range: [ ].

Avoid regular reflected light from entering into the sensor. The
light reception level is equal to or more than the limited sentivity
during background suppression function operation.
Delay response time or adjust the distance between Sensor
and workpiece so that the S ensor can detect it. The light
reception level is equal to or less than the limited sentivity
during background suppression function operation.
