KEYENCE products are strictly factory-inspected. However, in the event of a failure, contact
your nearest KEYENCE office with details of the failure.
1. WARRANTY PERIOD
The warranty period shall be for one year from the date that the product has been
delivered to the location specified by the purchaser.
2. WARRANTY SCOPE
(1) If a failure attributable to KEYENCE occurs within the abovementioned warranty period,
we will repair the product, free of charge. However, the following cases shall be
excluded from the warranty scope.
• Any failure resulting from improper conditions, improper environments, improper
handling, or improper usage other than described in the instruction manual, the
user’s manual, or the specifications specifically arranged between the purchaser and
KEYENCE.
• Any failure resulting from factors other than a defect of our product, such as the
purchaser’s equipment or the design of the purchaser’s software.
• Any failure resulting from modifications or repairs carried out by any person other
than KEYENCE staff.
• Any failure that can certainly be prevented when the expendable part(s) is
maintained or replaced correctly as described in the instruction manual, the user’s
manual, etc.
• Any failure caused by a factor that cannot be foreseen at a scientific/technical level
at the time when the product has been shipped from KEYENCE.
• Any disaster such as fire, earthquake, and flood, or any other external factor, such as
abnormal voltage, for which we are not liable.
(2) The warranty scope is limited to the extent set forth in item (1), and KEYENCE assumes
no liability for any purchaser’s secondary damage (damage of equipment, loss of
opportunities, loss of profits, etc.) or any other damage resulting from a failure of our
product.
3. PRODUCT APPLICABILITY
KEYENCE products are designed and manufactured as general-purpose products for
general industries.
Therefore, our products are not intended for the applications below and are not
applicable to them. If, however, the purchaser consults with us in advance regarding
the employment of our product, understands the specifications, ratings, and
performance of the product on their own responsibility, and takes necessary safety
measures, the product may be applied. In this case, the warranty scope shall be the
same as above.

Hints On Correct Use
• This product is just intended to detect the object(s). Do not use this
product for the purpose to protect a human body or a part of human body.
• This product is not intended for use as explosion-proof product. Do not
use this product in a hazardous location and/or potentially explosive
atmosphere.
•
To extend the cable length, use a cable with at least a 0.3 mm
2
nominal cross-section
area. Limit the length of cable extension to no more than 100 m.
•
If the amplifier cable is placed together with power lines or high voltage lines in the same
conduit, a detection error may occur due to noise interference, or the sensor may be
damaged. Isolate the amplifier cable from these lines.
•
When using a commercially available switching regulator, ground the frame ground
terminal and ground terminal.
•
Do not use the PZ-V/PZ-M series outdoors or in a place where extraneous light can
enter the light-receiving surface directly.
•
When the multi-reflective type is used for the detection of a target with high reflectivity
(e.g. mirror-surfaced object), proper detection or distance adjustment may be disabled.
In such a case, tilt the sensor head at some angle.
•
During maximum sensitivity setting, the detecting distance may vary due to a difference
in characteristics of each unit.
•
Be sure to check that the wiring is properly established. Improper wiring may cause a
decrease in sensitivity or overheating and sensor damage. (See “I/O Circuit”.)
•
To mount the sensor, use an M3 screw (coarse thread). Limit the tightening torque to
0.6 N•m or less.
•
To mount PZ-M71/V71, use an M4 screw (coarse thread). Limit the tightening torque to
0.7 N•m or less.
•
To attach the R-5 reflector, use an M3 screw (coarse thread). Limit the tightening torque
to 0.3 N•m or less.
•
The displayed value may vary depending on the surrounding environment, such as
temperature change or dust.
•
Use a stable power supply. The sensor cannot operate properly if the power supply is
unstable at power-on or if the ripple exceeds the specified range.
WARNING
Mutual Interference
•
The alternate-frequency type allows mutual interference suppression up to two sensors.
•
The alternate-frequency type is not available for the thrubeam type.
•
To suppress the mutual interference with the thrubeam type or with three or more
sensors, contact KEYENCE.
