Convergent Reective Micro Photoelectric Sensor Amplier Built-in
PM2 SERIES
Convergent reection sensing ensures stable detection
Stable detection by convergent reective mode
Stable detection
characteristics are
obtained since it is
convergent reective
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.

within the
convergent
area
30 mm

Background
Sensing object
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
reectivity.
Optimum setting
distance is 5 mm
0.197 in

Minute object detectable
A ø0.05 mm ø0.002 in

Sensing region
The sensing region (typical)
is represented by oblique
lines in the left gure.
However, the sensitivity
should be set with enough
margin because of slight
variation in products.
Correlation between material (15 × 15 mm 0.591 × 0.591 in) and sensing range
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
reective 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.

PRECAUTIONS FOR PROPER USE
All models
•When xing 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).

Plain washer
(Outer dia: ø6 mm ø0.236 in)

Purchase separately.
Mounting
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.
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
• T he 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.

•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.

Connector type
Cautions in plugging or unplugging a connector
Procedures of plugging or unplugging a connector
1
Insert a connector straight into a
sensor until the connector lug is
locked by the sensor hook.
2
When unplugging, give as much
stress as a connector lug can
be relieved from a hook. Then
unplug it.
Hook
Lug
5 N or less
Caution: Be sure to hold a
connector when plugging
or unplugging it. Do
not hold a terminal or
a cable when plugging
or unplugging the
connector. Otherwise, it
will cause a poor contact.

PRECAUTIONS FOR PROPER USE
• Do not plug or unplug a connector more than
10 times.
•Be sure not to give stress more than 5 N to a

If you do not follow the above cautions, it will
cause a poor contact.
