Precautions for Correct Use

●Installation

The Sensor may not achieve the characteristics given in this datasheet due to the ambient environment or installation location. Before using the Sensor, please acquire an adequate understanding and make a prior assessment of Sensor characteristics in your actual system.

●Operating Environment

· Do not use the Sensor in locations where dust, dirt, oil, andother foreign matter will adhere to the lens. This may preventcorrect temperature measurements.
· Do not use the Sensor in any of the following locations.
· Locations where the Sensor may come into contact withwater or oil
· Outdoors
· Locations subject to direct sunlight.
· Locations subject to corrosive gases (in particular, chloride,sulfide, or ammonia gases).
· Locations subject to extreme temperature changes
· Locations subject to icing or condensation.
· Locations subject to excessive vibration or shock.

●Noise Countermeasures

· The Sensor does not contain any protective circuits. Neversubject it to an electrical load that exceeds the absolute maximumratings for even an instance. The circuits may be damaged.Install protective circuits as required so that the absolutemaximum ratings are not exceeded.
· Keep as much space as possible between the Sensor anddevices that generates high frequencies (such as high-frequencywelders and high-frequency sewing machines) orsurges.
· Attach a surge protector or noise filter on nearby noise-generatingdevices (in particular, motors, transformers, solenoids,magnetic coils, or devices that have an inductance component).
· In order to prevent inductive noise, separate the connector ofthe Sensor from power lines carrying high voltages or largecurrents. Using a shielded line is also effective.
· If a switching requlator is used, check that malfunctions will notoccur due to switching noise from the power supply.

●Handling

· This Sensor is a precision device. Do not drop it or subject it toexcessive shock or force. Doing so may damage the Sensor orchange its characteristics. Never subject the connector tounnecessary force. Do not use a Sensor that has beendropped.
· Take countermeasures against static electricity before youhandle the Sensor.
· Turn OFF the power supply to the system before you install theSensor. Working with the Sensor while the power supply isturned ON may cause malfunctions.
· Secure the Sensor firmly so that the optical axis does notmove.
· Install the Sensor on a flat surface. If the installation surface isnot even, the Sensor may be deformed, preventing correctmeasurements.
· Do not install the Sensor with screws. Screws may cause theresist to peel from the board. Secure the Sensor in a way thatwill not cause the resist to peel.
· Always check operation after you install the Sensor.
· Use the specified connector (GHR-04 from JST) and connect itsecurely so that it will not come off. If you solder directly to theconnector terminals, the Sensor may be damaged.
· Make sure to wire the polarity of the terminals correctly. Incorrectpolarity may damage the Sensor.
· Never attempt to disassemble the Sensor.
