General Description
1.1 General Description
The LS series is a high-precision prole measurement sensor. The characteristics of this product are shown
below.
• This product achieves high-precision measurement by emitting a band-shaped laser beam and using a
light-plane-intersecting method that triangulates the reected light.
• Settings can be congured, measurements can be performed, and output can be generated from the
sensor. No amplier unit or other auxiliary devices are necessary.
• Various settings can be set from the sensor or from the dedicated setup software (LS-Navigator).
• It is possible to measure 4 areas with a single measurement. For each area, there are 13 types of
measurement functions to select from.
• There are 4 camera modes available. This enables you to select the optimum settings to match the
environment of the production line to be measured and the state of the target object.
With the light-plane-intersecting method, the reected light from the emitted band-shaped laser beam is
received by the light receiving element (CMOS), and the prole is then measured from the resulting image
data. With the light-plane-intersecting method, two processes are used to determine the height and position.
●Triangulation: To determine the height, this process obtains the received light waveform (the waveform of
the reected light) for each vertical line of the image.
●Projection transformation: To determine the horizontal position, this process mathematically calculates the
actual position from the image data.
(See the following gure.)

The LS series performs measurements by emitting a
parallel laser beam and receiving the reected light.
During measurement, ensure that the laser beam and
reected light is not blocked by the target object.
Before using the product, check that stray light, which
is reected by a wall or by highly reective objects,
does not have an effect on the measurements.
1.4.2 Installing the Sensor
1 Insert the included mounting screws (two M4 × 50 mm screws) into the mounting holes to temporarily afx
the sensor to a location that is roughly in the desired location.
2 Measure the distance between the sensor and the detection target object.
3 Adjust the sensor position on the basis of the measurement result, and then use the included nuts and
washers to x the screws in place.
