Sensors that are environmentally and user friendly.
Reducing environmental burdens further
Up to 60% less power consumption
The various lineup covers through the inclusion of a newly developed
custom integrated circuit.The
CX-400
series achieves reductions in
power consumption of up to 60%, averaging 44% reduction when
upgrading due to its unique design. These sensors reduce carbon
emissions and contribute to environmental friendliness.
Providing stable detection with low power
consumption
Strong against oil and coolant liquids
CX-41□/42□/49□
The lens material for
the thru-beam type,
retroreflective type
(excluding the
CX-48□)
and the diffuse reflective
type are made of a strong
acrylic that resists the
harmful effects of coolants.
These sensors can be
used with confidence even
around metal processing
machinery that disperses oil
mists. The protection mechanism also conforms to IP67
(IEC).

food processing machinery that
disperses ethanol based detergents.
The protection mechanism also
conforms to IP67 (IEC).
CX-44□/48□
Contributing to reduced carbon dioxide emissions
Electricity consumed by the
CX-400
series has been reduced on average
10.5 mA. Calculating 8 hours/day, 260
days (operating 5 days/week) for a total
of 2,080 hours/year leads to:
The
CX-400
contributes
Approx. 84.6 t
annually in carbon
dioxide reductions to the world
Caution: Set the

Remarkable penetrating power enables applications
such as package content detection.
Can sense differences as small as 0.4 mm
0.016 in,
CX-441/443
with hysteresis of 2 % or less
An advanced optical system provides sensing
performance that is 2.5 times approx. than conventional
models. Even ultra-small differences of 0.4 mm
0.016 in
can be detected accurately.
2.5 times the
sensing capability!
Height differences of as
little as 0.4 mm
0.016 in
can be detected at a
setting distance of 20 mm
0.787 in
Note: When sensing utilizing penetrating power, make sure to verify
using the actual sensor.
Hardly affected by colors
CX-441/443
Retroreflective type with polarizing filters
CX-491
Built-in polarizing filters ensure stable sensing even on a
specular object.
Both black and white objects can be sensed at the
same distances. No adjuster control is needed, even
when products of different colors are moving along the
production line.
30 % higher
sensing capability
CX-491
The difference in sensing ranges is 1% or less between non-glossy white paper with a

Note: The optimum condition is defined as the condition in which the
sensitivity level is set such that the stability indicator just lights
up when the object is absent.
Long sensing range of 5 m

possible with the red
LED type that is easy
to align with the beam
axis. Can be used for
wide automatic door
shutters.

achieves the
ultra-long sensing range
of 30 m
98.4 ft.
It can be
used for a stacker crane
or a multilevel parking
structure.
ENVIRONMENTAL RESISTANCE
Strong on dust and dirt
Because the
light source is an
infrared light, it is
strong on dust and
dirt compared to
the red beam type.
CX-412/413
Stronger noise resistance
The
CX-400
series has
a higher noise resistance
than its previons model. By
incorporating an inverter
countermeasure circuit that
appropriately shifts with peak
wavelength, the sensor now
resists high-frequency noise
from high-voltage inverter
motors and
inverter lights more effectively.
Fluorescent

Strong even in cold environments
Stable performance can be maintained even in
environments of –25 °C
–13 °F.
Inverter motor
ECO
Thoroughly eliminating unnecessary waste, Reducing many environmental burdens
The
CX-400
series has three different cable length
types and uses very simple packaging to reduce
waste. The bag is made of polyethylene and does not
emit toxic gasses.
