Safety Precautions
■ Precautions for Correct Use
Installation
Handling
• 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.
• 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.
• Keep the humidity between 40 to 70%.
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.

MEMS Thermal Sensors
D6T
• Use conductive or cotton type for gloves and finger cots.
• Wear a wrist strap on either the right or left hand.
• Put a conductive sheet (1 x 105 to 1 x 109Ω) on the working
table and connect to ground with the resistance of 1 MΩ.
• Hold the edge of the board so as not to touch the wiring,
electric parts or surface of the lens.
• 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 (PHR-4 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.
