The stable sensing range represents the sensing range for which the sensor
can satisfy all the given specifications with the standard sensing object.
The maximum operation distance represents the maximum distance for
which the sensor can detect at +20constant ambient temperature.
Usage within the stable sensing range is recommended for accurate
sensing applications.
Value is given for the stable sensing range.
The value represents the variation in the operation distance, that has been
set within the stable sensing range at +20, for an ambient temperature
drift from 0 to +55. (The value is for sensor head on its own.)
The length of the sensor head cable cannot be changed.

Make sure that the power supply is off while wiring or adding the units.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
In case noise generating equipment (switching regulator, inverter motor,
etc.) is used in the vicinity of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
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.
Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway.This can cause malfunction due to induction.
Be sure to use the optional quick-connection cable for amplifier
connection. Furthermore, extension up to 100m (50m: 5 to 8 units are
connected in cascade, 20m: 9 to 16 units are connected in cascade) is
possible with 0.3mm2or more, cable. However, in order to reduce noise,
make the wiring as short as possible.
Take care that when the cable is extended, the residual voltage rises.
Do not shorten or lengthen the sensor head cable.
This sensor is suitable for indoor use only.
Do not use the sensor at places having intense vibrations, as this can
cause malfunction.
Take care that the sensor does not come in direct contact with water, oil,
grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.
Make sure that the sensing end is not covered with metal dust, scrap or
spatter. It will result in malfunction.
Take care that stress by forcible bending or pulling is not applied directly
to the sensor head cable joint.
MOUNTING
3
Be sure to use a sensor head and amplifier as a set.
Disconnection method
Ԙ
Pressing the projection on the sensor
head connector, pull out the connector.
Note: Take care that if the connector is pulled out without pressing the projection, the pro-
jection may break. Do not use a sensor head connector whose projection has bro-
ken.Furthermore, do not pull by holding the cable, as this can cause a cable-break.
Connection method
Ԙ
ԙ
Insert the the sensor head connector into
the connector inlet till a click is felt.
Fit the cover on the connector.

front part of the mounting section to the DIN rail.
How to mount the amplifier
Take care that if the front part is lifted without pushing the amplifier forward, the
hook on the rear portion of the mounting section is likely to break.

Make sure that the power is off while cascading/removing the amplifiers.
Be sure to check the allowable ambient temperature, as it depends on
the number of amplifiers connected in cascade.
In case two, or more, amplifiers are connected in cascade, make sure to
mount them on a DIN rail.
When the amplifiers move on the DIN rail depending on the attaching
condition, fitting them between the optional end plates (MS-DIN-E)
mounted at the two ends.
When connecting in cascade, mount the amplifiers close to each other, fitting
them between the optional end plates (MS-DIN-E) mounted at the two ends.
When connecting more than two amplifiers in cascade, use the sub cable
(CN-71-Cغ) as the quick-connection cable for the second amplifier onwards.
This product does not incorporate the communication function When
this product used by cascading along with other than this product,
mount at the either side of the cascaded products.
