D6TMEMS Thermal Sensors
Safety Precautions
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, and
other foreign matter will adhere to the lens. This may prevent
correct temperature measurements.
• Do not use the Sensor in any of the following locations.
• Locations where the Sensor may come into contact with
water 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. Never
subject it to an electrical load that exceeds the absolute maximum ratings for even an instance. The circuits may be damaged. Install protective circuits as required so that the absolute
maximum ratings are not exceeded.
• Keep as much space as possible between the Sensor and
devices that generates high frequencies (such as high-frequency
welders and high-frequency sewing machines) or surges.
• Attach a surge protector or noise filter on nearby noise-generating
devices (in particular, motors, transformers, solenoids, magnetic
coils, or devices that have an inductance component).
• In order to prevent inductive noise, separate the connector of
the Sensor from power lines carrying high voltages or large
currents. Using a shielded line is also effective.
• If a switching requlator is used, check that malfunctions will not
occur due to switching noise from the power supply.
● Handling
• This Sensor is a precision device. Do not drop it or subject it to
excessive shock or force. Doing so may damage the Sensor or
change its characteristics. Never subject the connector to
unnecessary force. Do not use a Sensor that has been
dropped.
• Take countermeasures against static electricity before you
handle the Sensor.
• Turn OFF the power supply to the system before you install
the Sensor. Working with the Sensor while the power supply is
turned ON may cause malfunctions.
• Secure the Sensor firmly so that the optical axis does not
move.
• Install the Sensor on a flat surface. If the installation surface is
not even, the Sensor may be deformed, preventing correct
measurements.
• Do not install the Sensor with screws. Screws may cause the
resist to peel from the board. Secure the Sensor in a way that
will not cause the resist to peel.
• Always check operation after you install the Sensor.
• Use the specified connector (GHR-04 from JST) and connect
it securely so that it will not come off. If you solder directly to
the connector terminals, the Sensor may be damaged.
• Make sure to wire the polarity of the terminals correctly. Incorrect polarity may damage the Sensor.
• Never attempt to disassemble the Sensor.
• Do not use the cable harness to the other product.
