Mutual interference
When two or more sensors are installed in parallel or face to face, keep the
minimum separation distance specified below to avoid mutual interference.

Sensing range
The sensing range is specified for the standard sensing object. With a
non-ferrous metal, the sensing range is obtained by multiplying with the
correction coefficient specified below.

CONNECTION
Make sure that the power supply is off while connecting / disconnecting the
quick-connection cable.
Connection method
Holding the connector of the quick-connec-
tion cable, align its projection with the
groove at the top portion of the amplifier
connector.
Insert the connector till a click is felt.
Disconnection method
Pressing the projection at the top of the
quick-connection cable connector, pull out
the connector.
Note: Take care that if the connector is pulled out without pressing the
projection, the projection may break. Do not use a quick-connection cable whose
projection has broken.
Furthermore, do not pull by holding the cable, as this can cause a cable-break.

CASCADING UNITS
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 ca-
ble (CN-71-C ) 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.
Refer to the '
MOUNTING' for mounting / dismantling the amplifiers.
3
Cascading method
Mount the amplifiers, one by
one, on the 35mm width DIN
and set them close to each
other without any gap between
them.
Connect the quick-connection
cables to the amplifiers.
Mount the end plate (MS-DIN-E)
(optional) at both ends to hold
the units between their flat sides.
Tighten the screws to fix the
end plates (MS-DIN-E)
Dismantling
Pressing the projection at the top
of the quick connection cable
connector, pull out the connector.
Remove the amplifiers.
