available
About four times more robust in tightening
As the sensor can be securely tightened, it does not get
loose due to vibration or shock.
BASIC PERFORMANCE
Long sensing range
GX-12MLU(B)/N12ML(B) feature 1.6 times longer
sensing range than previous model [GX-12ML(B)]. It can
be mounted at a sufcient distance from the object.

FUNCTIONS
The normally open type [GX-(F)□U(-J)] is equipped with
a 2-color indicator. (The normally closed type and GX-N
have the operation indicator
instead.)
The operation is easily
observable from any direction
because the entire sensor
tail (transparent, GX-5SU(B):
enclosure) lights up.
Spatter-resistant type available
DC 2-wire type
As the enclosure is entirely
coated by uorine resin, the
sensor can be safely used
at a place where welding
spatters y around.
Both the pigtail cable and
the mating cable are also
spatter-resistant.
ENVIRONMENTAL RESISTANCE
GX-F□U-J
Simple wiring DC 2-wire type
Compact size: ø5.4 mm ø0.213 in
GX-5SU(B) is just 5.4
mm 0.213 in in diameter,
the smallest in existing
DC two-wire sensors. It
saves you space.
VARIETIES
The wiring cost is considerably reduced as it is DC 2-
wire type.
Further, each of GX-12M(L)U(B),
GX-18M(L)U(B),
GX-30M(L)U(B)
is available as a pigtailed
model that makes
replacement easy
and quick.

APPLICATIONS
Detecting traveling aluminum pallets
It can reliably detect even aluminum
pallets because of its long
sensing range.
Controlling depth of drilling
By detecting the dog, the sensor decides
the depth of the
drilled hole.
Positioning object at welding station
(GX-F□U-J only)
It can be safely used even where welding
sparks (spatter) y around.

2) 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 uctuation.
3) It is the leakage current when the output is in the OFF state.
4) The maximum load current varies depending on the ambient temperature. Refer to “I/O CIRCUIT AND WIRING DIAGRAMS” for more details.
5) When the cable is extended, the residual voltage becomes larger.

Do not use during the initial transient time (50 ms) after
the power supply is switched on.
Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.
DC 2-wire type
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.

For series connection (AND circuit) or parallel connection

When all sensors are in the ON state,
the load voltage VRL is given by:
VRL = VCC – n × 3 (V)
When all sensors are in the OFF state,
the load leakage current lcc is given by:
Vcc: supply voltage
(24 V DC max.)

Make sure that the load can
work properly at this voltage.

• The sensing range is specied for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefcient
specied below. Further, the sensing range also changes
if the sensing object is smaller than the standard sensing
object or if the sensing object is plated.
