Mounting with nut
• The sensor head and the controller are adjusted in order
to conform to the default specification linearity.
• In the event of replacing sensor heads, input the sensor
head’s characteristic code and conduct 3-point correction
(calibration).
• Should you use an extension cable, turn the sensor head cable
length selection switch located on the back of the controller
to “3 m + 7 m
9.843 ft
+ 22.966 ft
”. Then reintroduce the
power supply and conduct 3-point correction (calibration).
Conditions in use for CE conformity
• This product is CE compliant and complies with EMC
directives. EN 61000-6-2 is the applicable standard
that covers immunities relating to use of this product,
but in order to comply with this standard, the following
conditions must be satisfied.
Conditions
• The controller should be connected less than 10 m
32.808
ft
from the power supply.
• The signal line to connect with the controller should be
less than 30 m
98.425 ft
.
• A ferrite clamp must be mounted within 10 mm
0.394
in
from connector fitted onto the
GP-XBCC3
cable with
connector on one end for BCD output units.
Linearity in case of disc-shaped or cylindrical objects
• In case the sensing object is disc-shaped or cylindrical,
the linearity varies with the sensing object size.
In the event the sensing object is larger than the sizes
indicated in the table below, the linearity specification
(within ±0.3 % F.S.) is satisfied by performing zero-
adjustment and span adjustment when in contact using
the scaling function.

2) Mount such that the nuts do not protrude from the threaded portion.
Distance from surrounding metal
• As metal around the sensor head may affect the sensing
performance, pay attention to the following points.
<Embedding of the sensor head in metal>
• Since the analog output may change if the sensor head
is completely embedded in metal, keep the minimum
distance specified in the table below.

Mutual interference
• If several sensor heads are mounted close together, some specifications may
not be satisfied. Therefore, proceed with the interference prevention function
enabled.
The interference prevention function eliminates interference among sensors by
alternating sensor oscillations. Contact our office for details about time charts etc.
If not using the interference prevention function, leave a distance more than the
values given below.
PRECAUTIONS FOR PROPER USE
Refer to General precautions.
Others
• After turning on the power, wait 15 min. or more [20 min.for the
GP-XC3SE
(
-P
) and
GP-XC5SE
(
-P
)] before usingthe product.
The power supply circuit is not stable immediately after the power is
turned on, and this may cause measurement values to be distorted. In
addition, note that there will also be a muting period of approx. 2 sec.
