Compact Photoelectric Sensor Amplier Built-in
CX-400 SERIES Ver.2
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.
Strong against oil and coolant liquids
The lens material for
the thru-beam type,
retroreective type
(excluding the CX-48□)
and the diffuse reective
type are made of a strong
acrylic that resists the
harmful effects of coolants.
These sensors can be
used with condence even
around metal processing
machinery that disperses oil
mists. The protection mechanism also conforms to IP67
(IEC).

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.
ENVIRONMENTAL RESISTANCE
Strong even in cold environments
Stable performance can be maintained even in
environments of –25 °C –13 °F.
CX-412/413 Stronger noise resistance
Inverter motor
Fluorescent
light
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.
Ultra-long sensing range of 30 m 98.4 ft
The CX-413 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.
Long sensing range of 5 m 16.4 ft
A long 5 m 16.4 ft
sensing range is
possible with the red
LED type that is easy
to align with the beam
axis. Can be used for
wide automatic door
shutters.
CX-493 CX-413
BASIC PERFORMANCE
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.

FUNCTIONS

FGS (Foreground suppression) function
Light received
at position A
Light is not
received at
position B, so a
object is judged
to be present
Light received
at position B
For glossy object Object absent
OFF in this condition only ON in all other conditions
The sensor judges that an object is present when no
light is received at position B of the light-receiving
element (2- segment element). Accordingly, even
objects that are glossy can be sensed. This is useful if
the object and background are close together, or if the
object being sensed is glossy.

This is useful if the object and background are far
apart. The distance adjustment method is the same as
the conventional adjustment method for adjustable

It is useful for beam alignment of thru-beam type sensors. The optimum
receiver position is given by indicators, as well as an audio signal.
Notes: 1) The plug-in connector type sensor does not allow use of some sensor mounting brackets
because of the protrusion of the connector.
2) Set the distance between the sensor and the reflective tape to 0.1 m 0.328 ft (CX-482□: 0.4 m

Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) The sensing range and the sensing object of the retroreective type sensor are specied for the RF-230 reector (optional). The sensing range
represents the actual sensing range of the sensor. The sensing range : A of the table below may vary depending on the shape of sensing object. Be
sure to check the operation with the actual sensing object.

As the sensing object size becomes smaller than the standard
size (white non-glossy paper 200 × 200 mm 7.874 × 7.874 in), the
sensing range shortens, as shown in the left graph.
For plotting the left graph, the sensitivity has been set such that
a 200 × 200 mm 7.874 × 7.874 in white non-glossy paper is just
detectable at a distance of 300 mm 11.811 in.

The sensing region is
represented by oblique lines in
the left gure.
However, the sensitivity should
be set with an enough margin
because of slight variation in
products.

Lightness shown on the left may
differ slightly from the actual
object condition.
For plotting the left graph, the sensitivity has been set such
that a 200 × 200 mm 7.874 × 7.874 in white non-glossy paper
is just detectable at a distance of 200 mm 7.874 in. Contact us
for the sensing characteristics of 300 mm 11.811 in distance.
Please contact us for the sensing eld at the setting distance
