Precautions
Ratings and Performance
(1) Conform to the specified ratings and performance.
• Do not impose voltage exceeding the rated voltage, otherwise the Sen-
sor may be damaged.
• When supplying power to the Sensor, make sure that the polarity of the
power is correct, otherwise, the Sensor may be damaged. Do not con-
nect to an AC power supply.
• Do not short-circuit the load for the open collector output, otherwise the
Sensor may be damaged.
(2) Do not disconnect the connector connecting the Sensor Head and the con-
troller while power is being supplied, otherwise the Sensor may be damaged.
(3) Allow a warm-up period of approximately 10 minutes after turning ON the
power supply.
(4) Objects of certain materials or shapes may not be detectable, or the detec-
tion accuracy may not be sufficiently high. These include materials that are
transparent or have extremely low reflectivity, and objects that are smaller
than the Sensor's spot diameter or have extreme curvature or inclination.
Power Supply and Wiring
(1) Prior to turning ON the power supply after wiring is completed, check to make
sure that the power supply is correct, that there are no mistaken connections,
e.g., connections that would short-circuit the load, and that the load current is
appropriate. Incorrect wiring may result in damage to the Sensor or Unit.
(2) The total length of the Sensor cable or Amplifier cable must be 10 m or less.
Use an ZX-XC@A Extension Cable (order separately) if required to extend
the cable from the Sensor. Use a shielded cable to extend the Amplifier
cable. The shielded cable must be the same as that of the Amplifier cable.
(3) Do not lay a power supply cable for the ZX together with high-voltage lines or
power lines to prevent interference, damage, and malfunction.
(4) When using a commercially available switching regulator, ground the FG
(frame ground) terminal.
(5) If the power supply line is subject to surges, connect a surge absorber that
meets the conditions of the usage environment.
(6) When using a Calculating Unit, connect the corresponding linear ground of
the Amplifier Unit.
Environment
(1) Do not use the Sensor in strong electromagnetic fields or in an environment
where the operation of the Sensor is subject to the reflection of intense light
(such as other laser beams or electric arc-welding machines.)
(2) Do not operate the Sensor in the following locations:
• Locations subject to strong vibration.
