Noise
Countermeasures for noise depend on the path of noise entry, frequency components, and wave heights. Typical measures are as given in the
following table.
● Wiring
Cable
Unless otherwise indicated, the maximum length of cable extension is
100 m using wire that is 0.3 mm
Exceptions are indicated in Safety Precautions in individual product
information.
Cable Tensile Strength
When wiring the cable, do not subject the cable to a tension greater than
that indicated in the following table.
Note: Do not subject a shielded cable or coaxial cable to tension.
Repeated Bending
Normally, the Sensor cable should not be bent repeatedly.
(For bending-resistant cable, see
page C-4.)

Separation from High Voltage (Wiring Method)
Do not lay the cables for the Sensor together with high-voltage lines
or power lines. Placing them in the same conduit or duct may cause
damage or malfunction due to induction interference. As a general
rule, wire the Sensor in a separate system, use an independent metal
conduit, or use shielded cable.
Work Required for Unconnected Leads
Unused leads for self-diagnosis outputs or other special functions
should be cut and wrapped with insulating tape to prevent contact with
other terminals.
