Use with confidence at any time and anywhere
Have you ever thought that sensing was simple, but then when you tried to
use an rectangular inductive proximity sensor, the sensing was not stable?
It is because SUNX is the leading manufacturer of inductive proximity
sensors that we have been able to accumulate our sensor technology to
develop high-precision inductive proximity sensors that can be used at any
time and anywhere.
The requirements of our customers have been accommodated by basic
performance which is not to be found with other manufacturers.

We’re frustrated because
sensing results weren’t stable.
And the screw mounting
method makes it difficult to
adjust the sensor position.
When the sensing position changes
because of temperature variations
during the morning, afternoon and
nighttime, fine adjustments become
very difficult to make.
We want sensors that are good
at withstanding vibration and
shocks!
Are the sensors really safe to
be used in places where water
or oil will get on them?
We’d really like to have
sensors that let you see the

If you tighten the screws too
tightly, it will damage the

We’re frustrated because sensing results weren’t stable.
And the screw mounting method makes it difficult to adjust the sensor
position.
<Have you ever had this experience?>
i
The positions of rectangular inductive proximity sensors which
are installed using screws cannot be adjusted, and so they have
been designed with as short sensing ranges as possible to
minimize variations caused by the sensing range.
i
The sensor used as a replacement for maintenance has a longer
sensing range, so that not only the dog but also the base was
detected, meaning that position adjustment is necessary.

GX-䡺12 has a variation of 0.64 mm
0.025 in or less for a maximum

Thorough adjustment and control of sensing sensitivity greatly
reduces individual sensor differences and variations.

When the sensing position changes because of temperature variations
during the morning, afternoon and nighttime, fine adjustments become
very difficult to make.
<Have you ever had this experience?>
iTemperature differences between morning and nighttime
or as a result of seasonal changes cause slight shifts in
the sensing position.
iEvery time when the equipment is moved to a place with
different weather conditions, readjustments are necessary.
Stable sensing! Temperature characteristics vary within ⴣ8 %
Components such as the sensor coil and core and product design have been
totally revised to provide excellent temperature characteristics.
Stable sensing can be obtained regardless of the time of the day or the yearly
seasons.

We want sensors that are good at withstanding vibration and shocks!
The new integrated construction method used provides shock resistance of
10,000 m/s2 (approx. 1,000 G in X, Y and Z directions for three times each),
and vibration resistance which clears durability tests of between 10 and 500 Hz
(3 mm 0.118 in amplitude in X, Y and Z directions for 2 hours each).
In addition, resistance to impulse noize is approx. three times greater than for
previous models.

Highly resistant to water or oil!
IP68g* protective construction
The new integrated construction method
used improves environmental resistance

This product has been developed / produced for industrial use
only.
The output does not incorporate a short-circuit protection circuit.
Do not connect it directly to a power supply or a capacitive load.
Do not use during the initial transient time (50 ms) after the
power supply is switched on.
Extension up to total 100 m 328.084 ft is possible with a
0.3 mm2, or more, cable.

Notes: 1) “I” in the model No. specifi es
the different frequency type.
2) Close mounting is possible for up
to two sensors.
When mounting three sensors
or more at an equal spacing,
align the model with “I” and the
model without “I” alternately. The
minimum value of dimension “H”
should be as given below.

As the sensing object size becomes smaller
than the standard size (iron sheet 15 × 15 ×
t 1 mm 0.591 × 0.591 × t 0.039 in), the sensing
range shortens as shown in the left fi gures.
