Precautions
Install the sensor in a clean environment. Keep the filter (on the
front of the sensor) free from oil and dust. If affected by oil or
dust, clean the sensor as follows:
1. Use a blower brush (used to clean camera lenses) to blow
large dust particles from the surface. Do not blow the dust
away with your mouth.
2. Use a soft cloth (for lenses) with a little alcohol to remove the
remaining dust. Do not use a scrubbing action when clean-
ing. A scratch on the filter could result in the sensor malfunc-
tioning.
JCONNECTOR
When removing the connector from the sensor, be sure to hold
the connector and pull it along with the attached cable.
If pressure is applied to the cable alone, it will damage the lock
mechanism inside the connector.
JINTERFERENCE
Z4D-F04A/D microdisplacement sensors can be installed within
close proximity to each other and operate independently without
interference (refer to the figures below). However, if they are
installed at an oblique angle to each other, interference may
result.
When using the microdisplacement sensor in combination with
another type of sensor (such as a photoelectric sensor), the
sensor beams should be as close to perpendicular as possible.
JENVIRONMENT
Refrain from using the microdisplacement sensor in a strong
electromagnetic field or in an environment where the operation of
the sensor is subject to the reflection of intensive light (such as a
laser beam or an electric arc welding machine).
The microdisplacement sensor cannot accurately sense a
mirror-like object, a transparent object, one with an extremely
small reflection ratio, an object smaller than the diameter of the
sensor’s sensing spot, or an inclined object.
JWIRING
The power supply cable for the Z 4D-F04A/D should not be wired
with high-voltage lines or power lines in order to avoid
interference, damage, or malfunction.
Do not solder wires to the sensor connector, or the sensor may
malfunction.
JOTHERS
Do not use switching power supplies that generate excessive
noise, which may cause sensing errors.
The following LC filter effectively reduces noise.
Sensor Power
source
The sensor cannot sense an object accurately if the surface of
the object consists of different materials placed next to each
other (refer to the figures below). In such a case install the
sensor so that the boundaries of the materials and the sensor are
parallel.
