1. Safety precautions
Head the following precautions to prevent injury or accidents.
(1) We take no responsibility for troubles caused by the product usage that is not specified in this specification.
Using the sensors in any way which causes their specifications to be exceeded may generate abnormally high levels of
heat, emit smoke, etc., resulting in damage to the circuitry and possibly causing an accident.
(2) Before connecting a connector, check the pin layout by referring to the connector wiring diagram, specifications diagram,
etc., and make sure that the connector is connected properly. Take note that mistakes made in connection may cause
unforeseen problems in operation, generate abnormally high levels of heat, emit smoke, etc., resulting in damage to the
circuitry.
(3) If the sensor is abnormally heated or emits an unusual odor, immediately turn off the main power supply to stop
operation.
(4) The fact remains that electrical components and devices generally cause failures at probability. Furthermore, their
durability varies with use environments or use conditions. In this respect, we ask you to check for actual electrical
components and devices under actual conditions before use without fail.
(5) The failure modes of this sensor include a short circuit (short-circuit), an open circuit (open-circuit) between each
terminal, the occurrence of temperature rise of the equipment (short-circuit), abnormality of a temperature output, etc.
If the quality of this sensor is expected to have a significant impact on human life or property, it is recommended to allow
a sufficient margin to guarantee characteristics and performance values described in this specification, and to ensure
safety by fully considering the fail-safe design shown in the following consideration.
・ Provide protection circuits and protection devices to ensure system safety.
・ Provide of a redundant circuit so that a malfunction does not make the system unsafety.
(6) If there is any doubt about the safety of this sensor, notify us immediately and make sure to carry out a technical
examination at your end.
(7) Do not disassemble or modify the sensor.
2. Precaution for fundamental structure of sensor
Infrared Array Sensor is a thermopile type infrared sensor which detects the amount of infrared rays.
In general, the sensor output may change in the following cases.
Be sure to check the performance and reliability under actual operating conditions, and correct, if necessary, the output under
the actual operating conditions.
If the sensor partially changes temperature.
・If there is a heating element (MCU, power supply, etc.) near the sensor.
・If the sensor unit is exposed to warm or cold air.
・If the sensor body is in contact with the housing of the equipment.
If there is an obstacle between the sensor and the target object.
・If there is an object between the sensor and the target object that does not easily transmit far infrared rays,
such as glass, acrylic, or steam.
・If a foreign matter (dust, dirt, water drops, etc.) that inhibits transmissions of far-infrared rays is attached to the lens of
the sensor body.
3. Use environment
(1) Temperature: See the specifications
(2) Humidity: 15 % to 85 % R.H. (Avoid freezing and dew condensation)
(3) Atmospheric pressure: 86 to 106 kPa
(4) Vibrations and shocks may damage the sensor, and cause malfunction and performance deterioration. If loads and shocks
are applied on the lense, the damaged sensor may cause malfunction and performance deterioration.
(5) The product is not water/splash-proof. Therefore, take measures against water, dust, condensation, and freezing depending
on the operating environment. If water drops adhere to a soldered part, a short circuit will occur due to solder migration.
Therefore, take measures to prevent water from leaking.
(6) Avoid use and storage in the corrosive gas (organic solvent, sulfurous acid and hydrogen sulfide gases) to avoid malfunction
and performance deterioration.
(7) Use surge absorbers as applying the external surge voltage may damage the internal circuit.
(8) Malfunction may occur near electric noises from static electricity, lightning, broadcast or amateur radio stations and mobile
phones.
