Detection of Different
Color Objects at a
Certain Distance
192
Amplifier Built-in Adjustable Range &
Fixed-focus Reflective Photoelectric Sensor
Marked
Conforming to EMC Directive
Not Affected by Color
The color or size of the object does not
affect its sensing.
Waterproof
The sensor can be hosed down
because of its IP67 construction. The
equipment on which the sensor is
mounted can be washed without any
problem.
Not Affected by Background
The sensor does not detect the
background beyond the set distance
since it is distance settable type.
Robust
Its robust enclosure is made of die-
cast zinc alloy.
Insusceptible to Dust
The sensing performance is less af-
fected by dust as it does not depend
on the incident light intensity.
High-speed Response Time: 1ms
It can be used on a high speed
assembly line.
Note: However, take care that if it is exposed to
water splashes during operation, it may
detect a water drop itself.
Background (specular)
Dust
Adjustable Range & Fixed-focus Reflective Type
The sensing range for which the
sensor detects an object is determined
by the incident beam angle, regardless
of the incident light intensity.
Convergent Reflective Type
The sensor detects an object only in
the overlapping area of the emitting
and receiving envelopes. The
detectability is a little influenced by the
reflectivity of the object surface.
Diffuse Reflective Type
The sensing range changes with the
reflectivity and size of the sensing object.

This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.
Mounting
•The tightening torque should be 1.17Nm or less.
•
Care must be taken regarding the sensor mounting direc-
tion with respect to the object’s direction of movement.

Sensing object
Sensing object
Sensing object
Do not make the sensor
detect an object in this
direction because it may
cause unstable operation.
•When detecting a specular object (aluminum or copper
foil) or an object having a glossy surface or coating,
please take care that there are cases when the object may
not be detected due to a small change in angle, wrinkles
on the object surface, etc.
•When a specular body is present below the sensor, use
the sensor by tilting it slightly upwards to avoid wrong
operation.
•If a specular body is present in the background, wrong
operation may be caused due to a small change in the
angle of the background body. In that case, install the
sensor at an inclination and confirm the operation with the
actual sensing object.
•Do not install the sensor at a distance of less than 50mm
from the object because the sensing is unstable in this
range.
Wiring
•The output of RX-LS200-P is not incorporated with a
short-circuit protection circuit. Do not connect it directly to
a power supply or a capacitive load.
Others
•Do not use during the initial transient time (50ms) after the
power supply is switched on.

Turn the distance adjuster fully counterclockwise
to the minimum sensing range position (50mm
approx.).
(Do not turn excessively.)
Place an object at the required distance from the
sensor, turn the distance adjuster gradually
clockwise, and find out point (A) where the sensor
changes to the light received condition.
Remove the object, turn the distance adjuster fur-
ther clockwise, and find out point (B) where the
sensor changes to the light received condition
again with only the background.
When the sensor does not go to the light
received condition even if the adjuster is fully
turned clockwise, point (B) is this extreme point.
The optimum position to stably detect objects is the
center point between (A) and (B)
