6. Installation
(1) Mounting hole dimensions
Use the mounting fixture provided to avoid the effect of inductive noise.
(2) Caution in choosing the installation place
Do not use the transmitter in any of the following places to keep the performance.
1) A place where water, oils, particles, dust and/or chemicals may scatter.
2) A place where aqueous vapor, fumes and/or corrosive gases may cause optical signal
attenuation.
Do not use any thinner type solvent for cleaning since the spotlight and acceptance surfaces
consist of plastics.
3) A place where the equipment may be exposed to a temperature, humidity, vibration or impact
out of the rated range.
Anti-vibration measures are required if the equipment is continuously exposed to vibration or
impact even within the rated range.
4) A place near a magnet, motor or other devices that generate a strong magnetic field or an
inverter or another devices or electric wire that generate a strong noise.
5) A place where the sunlight or candescent light containing strong infrared rays enters the
receiver section within an angle not larger than 10 degrees from the center of the optical axis of
the equipment. Use this equipment indoors.
6) A place where a person or an obstacle possibly interrupts optical path, or where aqueous vapor
or fumes may be generated in the optical path between the transmitter and the receiver to
dampens the optical signals.
7) A place where any reflected beam or light beam from another photoelectric switch is on the
optical path of the transmitter, thus causing optical interference on this equipment.
8) A place where the optical axis may deviate 1.5 degrees or more by the meandering, vibration or
impact of a moving body during communication with the moving body.
