Compact Size: "5.4mm Long Sensing Range
GX-5SU(B) is just 5.4mm in diameter,
the smallest in existing DC two-wire
sensors. It saves you space.
The GX-U series features 1.6 times
longer sensing range than conventional
models. As it can be mounted at a suffi-
cient distance from the object, there is no
fear of the sensor and the object colliding.
The tightening torque has been im-
proved to approx. four times greater
than that of conventional models
because of its thick case. As the
sensor can be securely tightened, it
does not get loose due to vibration or
shock.
The normally open type is equipped
with a 2-color indicator.
The normally closed type has the
operation indicator instead.
The operation is easily observable
from any direction because the entire
sensor tail lights up.
Simple Wiring
The wiring cost is considerably
reduced as it is DC 2-wire type.
Further, each of GX-12MU(B),
GX-18MU(B), GX-30MU(B) is avail-
able as a pigtailed model (300mm long
cable with attached connector) that
makes replacement easy and quick.
Spatter-resistant Type Available
As the enclosure is entirely coated by
fluorine resin, the sensor can be safely
used at a place where welding spatters
fly around.
Both the pigtail cable and the mating
cable are also spatter-resistant.

Note: The maximum operation distance stands for the maximum distance for which the sensor can detect the standard
sensing object.
The stable sensing range stands for the sensing range for which the sensor can stably detect the standard
sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation.
It can reliably detect even
aluminum pallets because
of its long sensing range. It can be safely used even where
welding sparks (spatter) fly around.
By detecting the
dog, the sensor
decides the depth
of the drilled hole.

Pigtailed type
Pigtailed sensors are optionally available. [Standard type is cable type. However, there are no pigtail options for GX-5SU(B), GX-8MU(B), or GX-8MLU(B).]
When ordering this type, add suffix .‘-J’ to the model No.
(e.g.) The pigtail type of GX-12MLUB is ‘GX-12MLUB-J’.

PRECAUTIONS FOR PROPER USE Refer to P.836lfor general precautions.
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 under the value given
below.
Distance from surrounding metal
•As metal around the sensor may affect the sensing
performance, pay attention to the following points.
Mutual interference
•When two or more sensors are installed in parallel or face
to face, keep the minimum separation distance specified
below to avoid mutual interference.
•The surrounding metal will affect the sensing per-
formance. Keep the minimum distance specified in the
table below.
•Sensing range may decrease if the sensor is completely
embedded in metal. Especially for the non-threaded type
and the non-shielded type, keep the minimum distance
specified in the table below.
•Tighten with the cup-point of a set screw (M4 or less).

PRECAUTIONS FOR PROPER USE Refer to P.836lfor general precautions.
Sensing range
•The sensing range is specified for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefficient
specified below.
Wiring
•
The sensor must be connected to a power supply via a
load. If the sensor is connected to a power supply without a
load, the short-circuit protection makes the sensor inoperable.
(The output stays in the OFF state and the indicator does
not light up.) In this case, rectify by connecting the power
supply via a load. Now, the sensor becomes operable.
Further, take care that if the power supply is connected with
reverse polarity without a load, the sensor will get damaged.
2-color indicator (Normally open type only)
•When the sensing object is in the stable sensing range,
the LED lights up in green, and when the sensing object is
in the unstable sensing range, the LED lights up in
orange. While the LED lights up in green, the sensing is
performed stably without being affected by temperature
drifts or voltage fluctuations.
•For series connection (AND circuit) or parallel connection
(OR circuit) of sensors, take care of the following.
•The residual voltage of the sensor is 3V. Before connect-
ing a relay as the load, take care of its actuation voltage.
(Some 12V relays may not be usable.)
Series connection (AND circuit) Parallel connection (OR circuit)
Protection cover (Optional)
•It protects the sensing surface from welding sparks (spat-
ter), etc.
Others
•Do not use during the initial transient time (50ms) after the
power supply is switched on.
•When the sensor is mounted on a moving base, stress
should not be applied to the sensor cable joint.
Note: The sensing range also changes if the sensing object is plated.
Note: Mount the protection cover so that there is no gap between it and the
sensing surface.
