PY series
•This product is not for outdoor use (it may shorten the product lifetime and cause electric shock)
•Do not use this product in places with flammable or explosive gases (it does not have
an explosion-proof structure, so there are fire or explosion risks)
•Do not use the product in places where vibrations or shocks exceed the reference values
(it has a double insulation structure, but the components may be damaged)
• When the lens of the photo sensor is contaminated by foreign substances, use a dry
piece of cloth and wipe off the substance lightly. Never use thinner or organic solvents.
•Separate high voltage cable and power line from the sensor wire. Be cautious since using the
same pipe during wiring could cause malfunction.
•This product has IP67 protection rating , which means that it is partially waterproof, but it
cannot be used in places that are constantly flooded.
• If the cable needs to be extended, use over 0.3 ㎟ and be cautious because of a
possible sudden voltage drop.
•When using the sensor under lights with high frequency, such as fluorescent lamps or mercury
lamps, block it with a light shading plate and avoid the lens from facing the light directly.
•Malfunction can occur due to mutual interference when using more than 2 pairs of through-
beam type photo sensors. Therefore, leave enough space for the mutual separation
distance and install the light emitters and the light receivers in alternating positions.
• Using inductive load (relay, coil) for the output can cause an instantaneous increase in
load by more than two times and damage the TR of the output. Therefore, please set
half of the maximum load.
• There is an over-current protecting circuit within the output side that breaks the output when the
current is higher than the rated load current. Therefore, please set within 70% of the maximum load.
• Do not use the product in places with heavy dust or debris that can contaminate the
lenses and consequently cause malfunctions.
•
The contents of this manual may be changed without prior notification
• Any use of the product other than those specified by the manufacturer may result in
personal injury or property damage.
• When using the Switching Power Supply as power source, ground the Frame
Ground (F.G.)terminal and be sure to connect the noise-cancelling condenser
between OV and F.G. terminals
• Be sure to observe the safety precautions mentioned above as cautions to prevent product
malfunctions.
