PM2
SERIES
Amplifier Built-in
Certified
Convergent reflection sensing ensures stable detection
Stable detection by convergent reflective mode
Stable detection
characteristics are
obtained since it is
convergent reflective
type and senses a
limited area.
Hardly affected by background
Even a specular
background does not
affect the sensing
performance if the
sensor is located 30 mm
1.181 in
away from it.
Sensing object
Detects
an object
within the
convergent
area
30 mm
1.181 in
Background
However, the specular background should be a
plane surface, directly facing the sensor. A spherical
or curved background may be detected.
Dark object detectable
Since the sensor is very
sensitive, it can detect
even a dark object of low
reflectivity.
Optimum setting
distance is 5 mm
0.197 in
approx.
Cable type is also available
Cumbersome soldering is not required.
It saves space and improves reliability.

PRECAUTIONS FOR PROPER USE
All models
•
Never use this product as a sensing device
for personnel protection.
•
In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
Mounting
•
When fixing the sensor with screws, use M3 screws and
the tightening torque should be 0.49 N·m or less.
Further, use small, round type plain washers (ø6 mm
ø0.236 in).

Purchase separately.

Wiring
•
Make sure to connect terminals correctly as the sensor
does not incorporate a reverse polarity protection circuit.
•
If the sensor is being used in a noisy environment,
examine the extent of noise. Further, if equipment, such
as motor, solenoid or electromagnetic valve, which
generates a large surge, is present near the sensor,
connect a surge absorber to the equipment.
Setting
• The
optimum setting
distance (distance to
convergent point) is
5 mm
0.197 in.
The sensor is not affected
even by a specular
background if it is located
30 mm
1.181 in,
or more,
away from the sensor.

The bars in the graph
indicate the sensing range
(typical) for the respective
material. However, there
is a slight variation in the
sensing range depending on
the product.
Further, if there is a
reflective object (conveyer,
etc.) in the background of
the sensing object, since
it affects the sensing,
separate it by more than
twice the sensing range
shown in the left graph.

Others
•
Do not use during the initial transient time (50 ms) after the
power supply is switched on.
•
Take care that the product does not come in direct contact
with oil, grease, or organic solvents, such as, thinner, etc.
However, the specular background should be a plane
surface, directly facing the sensor. A spherical or curved
background may be detected.
