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 pro-
tect the human body.
• The CZ-V21(P)/V22(P) does not have an explosion-proof struc-
ture. 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-
