Product
Description
The
KLSA-PN
laser
ranging
sensor
is
a
precision
instrument
that
uses
laser
technology
to
achieve
non-contact
distance
measurement.
It
determines
the
distance,
position
or
displacement
of
the
target
object
by
emitting
laser
and
analyzing
the
reflected
signal.
Its
core
advantages
are
high
precision,
long
distance,
fast
response
and
anti-interference
ability.

Functions
Hysteresis
Function
Output
[Hno][Hnc].
Set
a
switch
point.
If
the
measured
value
changes
around
the
sensing
range,
the
hysteresis
function
can
keep
the
output
switch
state
stable.
Window
Function
Output
[Fno][Fnc].
Set
two
switch
points
for
near
and
far.
Use
the
window
function
to
monitor
the
defined
allowable
range.
Turn
Off
the
Laser
The
sensor
can
set
the
red
dot
to
indicate
the
laser
on
and
off
by
pressing
the
button.
It
does
not
affect
the
normal
distance
measurement.
Installation
Installation
Conditions
-
Install
the
device
so
that
the
object
to
be
measured
is
within
the
measuring
range
of
0.03...22
m.
-
The
sensor
has
a
fixed
accuracy
range
of
22
m.
Do
not
measure
objects
within
a
range
>
22
m.
-
The
customer
should
also
avoid
reflective
objects
in
the
direct
optical
path
of
the
sensor
within
a
range
>
22
m.
Otherwise,
the
measured
values
may
be
inaccurate.
