LS-H91
Reflector
Sheet rolls
The coaxial retroreective sensor with a spot diameter
of approx. ø1 mm ø0.039 in (at a 1 m 3.281 ft sensing
distance), can measure amounts remaining on sheet rolls
with high precision.

Industry standard mounting pitch
The mounting pitch for sensor heads is
25.4 mm 1.000 in, the same industry standard as the
CX-400 series Ver.2 general purpose photoelectric
sensors. Hence, existing mounting brackets can be used
even when replacing general purpose sensors with laser
sensors.

Easy and accurate adjustments
A spot-size adjuster is built into the back of the sensor
head allowing the user to adjust the sensor easily while
viewing the spot. The adjuster is adjustable with a
screwdriver to avoid accidents during maintenance or
any other time the sensors are handled.

Its linear sensing area enables more
stable detection of objects with complex
shapes.
Because its spot shape can be adjusted in accordance
with the object, it can be easily set to detect even the
minutest object from a remote location.

Threshold tracking function saves
maintenance time
This function seeks
changes in the light emitting
amount resulting from
changes in the environment
over long periods (such
as dust levels), so that
the incident light intensity
can be checked at desired
intervals and the threshold
values can be reset
automatically. This helps to
reduce the man-hours for
maintenance.

Wiring and space saving
The quick-connection cables enable reductions in wiring.
(connector type)
The connections and man-hours for the relay terminal
setup can be reduced and valuable space is saved.
Also, LS-400 series ampliers can of course be
connected side-by-side with a connector type amplier
of FX-500/300 series digital ber sensors or DPS-400
series digital pressure sensors.
Note: Because the transmission method varies depending on the
ampliers, check the instruction manual for the ampliers when
connecting them.

By adjusting the hysteresis,
convexo-concave parts of uneven
objects can be cancelled enabling
more stable sensing.
The sensor judges any object
outside the range of incident light
intensity established by two set
threshold values.
Hysteresis mode Window comparator mode
By combining two outputs, wide
array of control is possible, allowing
you to detect meandering objects,
for example.
Only rapid changes in light received
are detected, which enable the edge of

Frequently used functions such as response time,

Emission halt function
If you do not want to
place a laser spot in
the visual range of
the image processor,
you can stop the laser
radiation using the
emission halt signal
from the external input.
Cable type allows external input
The LS-401-C2 cable-type amplier is equipped with an
external input wire (5-core). It is ideal to use the laser
sensor at places where external teaching or laser light
emission halting is to be carried out, or at the places
where the laser sensor is to be used separately.
Interference prevention function
The automatic interference
prevention function prevents
against interference among
up to 4 sensors.
Setting conditions viewed at a glance (D-CODE)
The amplier setting is shown as an 8-digit code. Handy
for remote indications and follow-ups.
Accurately sense the minutest variations
(M.G.S. function)
When sensing at close range or when the target objects
are transparent or minute, adjust the sensor receiving
sensitivity to one of 3 levels (U-LG mode: 4 levels) for
the optimal setting. In addition, changing the receiving
sensitivity will not effect the response time.
