WARNING
If you ignore the advice with this mark, death or serious injury could result.
CAUTION
If you ignore the advice with this mark, injury or material damage could re-
sult.
In this Instruction Manual, and are indicated de-
pending upon the level of danger. Please observe them strictly for the
safe use of this sensor.

Installation of a touch bumper
You are requested to always install a touch bumper when this product is
used on an automatic guided vehicle (AGV).
CAUTION
٨
Use outside Japan
This sensor conforms to the EMC directive. However, it is not certified
by a competent body in accordance with other country safety standards.
Since each country has its regulations, please follow the local and na-
tional regulations of the country where this sensor is used.
CAUTION
٨
Fail-safe measures
This sensor is meant for proximity detection and does not possess con-
trol functions for safety maintenance.
If fail-safe measures are required, consider their incorporation in the to-
tal system.
Further, do not connect the sensor output directly to a stopping mecha-
nism (brake).
CAUTION
٨
Periodical maintenance check
The person incharge must periodically confirm the performance of the
product and maintain a record of such checks. In addition, whenever
the operating environment of the product is changed due to system
modification, etc., performance check must be done.

Mount the sensor, horizontally, at least 300mm
above the floor, to avoid reflection from the floor.
300mm or more
Notes: 1)
2)
The sensing range is specified for white non-glossy paper (300
300mm).
Obtain the current consumption by the following calculation.
Current consumption = Power consumption
¸
Supply voltage
(e.g.) When the supply voltage is 12V, the current consumption (operating condition) is:
1.5W
¸
12V = 0.125A = 125mA
