3) The length of the sensor head cable cannot be changed.
4) The given weight of the threaded type sensor head is the value including the nuts and the
toothed lock washer.
5) Take care that the output voltage is reduced due to the resistance of the wiring cable.
2 CAUTIONS
Make sure that the sensor head and the amplifier which have the same
production serial number (7 digit) are used in combination. Since adjust-
ment is done before shipment, if items with different production serial
numbers are combined, the sensing characteristics will deteriorate even if
they have the same model Nos.
<Sensor head>
(Example)
Serial number: 4A6N 055
Make sure that the power supply is off while wiring.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that
the frame ground (F.G.) terminal of the power supply is connected to an
actual ground.
For 3mm sensing
In case noise generating equipment (switching regulator, inverter motor,
Front sensing
etc.) is used in the vicinity of this product, connect the frame ground
type sensor head
(F.G.) terminal of the equipment to an actual ground.
GP-A14F(I)
0 to 3mm Do not run the wires together with high-voltage lines or power lines or put
Iron sheet them in the same raceway. This can cause malfunction due to induction.
15 15 t1mm
Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.
The length of the sensor head cable cannot be changed.
Make sure that stress by forcible bend or pulling is not applied directly to
the sensor cable joint.
The alarm output is not incorporated with a short-circuit protection
circuit. Do not connect it directly to a power supply or a capacitive load.
Do not use the sensor at places having intense vibrations, as this can
cause malfunction.
Take care that the product does not come in direct contact with water, oil,
grease, organic solvents, such as, thinner etc., strong acid or alkaline.
Make sure that the sensing end is not covered with metal dust, scrap or
spatter. It will result in malfunction.
For stable sensing, carry out the adjustments 30 min., or more, after the
power supply is switched on.
3 MOUNTING
Make sure that the sensor head and the amplifier which have the same
production serial number (7 digit) are used in combination.
The length of the sensor head cable cannot be changed.

Distance from surrounding metal
As metal around the sensor may affect the sensing performance, pay
attention to the following points.
<Embedding of the sensor in metal>
Since the analog output may change if the sensor is completely embed-
ded in metal, keep the minimum distance specified in the table below.

D
Metal
Front sensing type sensor head
GP-A14F(I) can be used by being completely
embedded in metal. However, the surrounding metal
should not protrude beyond the sensing face.

Mutual interference
If several sensor heads are mounted together, since the specifications
may not be met, keep the minimum separation distance given below.

Dependence of output characteristics on material (typical)
Take care that, depending upon the material of the sensing object, the
output differs as shown in the figures below.

Mounting with screws
Use two commercially available M4 (length
10mm or more) pan head screws.
The tightening torque should be 1.2N m or less.
Please arrange the pan head screws and
nuts separately. The mounting holes for the
