BE SURE TO READ THESE MESSAGES CAREFULLY

Warning

• The CZ-V21(P)/V22(P) is just intended for the detection of target
objects. Do not use the CZ-V21(P)/V22(P) in a safety circuit to pro­tect the human body.

• The CZ-V21(P)/V22(P) does not have an explosion-proof struc­ture. Do not use it in a location where any flammable gases, liquid
or powder exist.

• The CZ-V21(P)/22(P) is a direct current type sensor. Application of
the AC power may lead to burst or fire.

• Do not directly look at the emitted LED beam.

• The CZ-H32/H35S/H37S/H72 are the Class 1 LED product in which
the light source LED is located in the amplifier unit.

• The CZ-H52 is the Class 1M LED product.

*When using the CZ-H52, be sure to read Precaution on Using CZ-

H52 on page 8.

MOUNTING THE SENSOR HEAD

■ Extraneous light

A detection error may occur when the light from high-frequency lighting equipment
such as an inverter fluorescent lamp directly enters or reflected on the target into
the emitter. In such a case, apply a light shield plate or change the location of the
sensor

.

Inverter fluorescent lamp, etc.

Light shield plate

■ Ta rget movement and sensor orientation

To stabilize the sensor output at a border, mount the sensor as shown in the
following figure as much as possible.

Movement direction

■ When using the CZ-H32

When detecting a metal surface or glossy target

When a target has a metal or glossy surface, the calibration/differentiation
may fail. To detect such a target, tilt the sensor head by approximately 10 to
15 degrees.

10° to 15°

■ When using the CZ-H35S/CZ-H37S/H72

When a target has a glossy surface (a birefringence target such as an ori­ented film), the detection may fail depending on the mounting orientation. To
detect such a target, displace the sensor head by approximately 45 degrees.

SAFTY PRECAUTIONS

• Isolate the sensor cable from the power line or the high voltage line.
The use of these lines in the same pipe generates noise, which may cause
malfunction.

• When a number of colors enter into the beam spot, they are averaged
down in recognition, resulting in the output of the color that is different from
the preset color.

•To extend the amplifier cable, use the cable with the nominal cross-sec­tional area no less than 0.3 mm

• When using the commercially available switching regulator,
be sure to earth the frame ground terminal and the ground terminal.

• Do not use the sensor outdoors.

• Even in the detection of the same color, the displayed value may vary due
to the reason such as amplifier’s individual characteristics, sensor head
cable length, and different mounting conditions.

Precaution on Using the CZ-H52

This sensor uses an ultraviolet LED as the light emitting source and a light
receptor element that has the enhanced sensitivity in the visible region. The
sensor is designed to reliably and easily detect fluorescent marks (such as
hidden marks painted with fluorescent paint, or fluorescent marks painted
with fluorescent paint).

■ Caution

Class 1M LED

The LED emits powerful ultraviolet light while turned on, which can be very
dangerous to the unprotected human eye. Do not view directly with optical
instruments (such as a microscope or a telescope or a magnifiers).
Doing so may result in eye injury.
If there is a risk of reflected ultraviolet light entering the eye, wear protective
goggles and avoid all risks of direct exposure to the eye.

■ Precaution on Detection

Some fluorescent objects cannot be detected by this sensor even though they
may be visible to the human eye. Check the types of fluorescence before use.
For your information, fluorescent materials include those which emit fluores­cent light, phosphorescent light, and light accumulated from light-accumula­tive materials.
