Gas Sensors
QGC Pyroelectric Infrared Gas Sensors, Analog
Overview
Applications
KEMET’s QGC thin film pyroelectric gas sensors can be
reduced in physical size and still provide high sensitivity
with fast frequency operation, enabling this highly stable
1 to 4 element sensor in a TO39 package.
• Gas and gas flues
• HVAC (refrigerant or CO2-driven ventilation system)
• Industrial process and safety
• Medical capnography and anesthesia
• Handheld breath analysis and breath rate measurement
• Breath actuated dispenser
• Automotive cabin air quality
• Exhaust (CO2 content)
• Home and building technology
• Environmental monitoring (ambient CO2 level)
• Pollution air quality in home, office and car
(excessive CO2 level)
The sensor element is built into a low noise circuit that
has an internal CMOS operational amplifier with a 10 GΩ
feedback resistor outputting a voltage signal centred
around half the supply rail.
Benefits
• Fast, stable response over a wide operating frequency range
• 1, 2, or 4 sensor elements in one package
• TO39 package
• Analog output
• Integrated op amp

Environmental Compliance
All KEMET Gas Sensors are RoHS and REACH Compliant.
Article 33(1) of the REACH Regulation states that manufacturers and importers of articles (products) are required to notify their
customers of the presence of any Substances of Very High Concern (SVHC) in their products exceeding 0.1% by weight and provide
instructions on safe use of the product.
KEMET Corporation reports regarding the Article 33(1) of REACH Regulation as follows:
1. Applicable Product: Gas Sensors (QFC & QFS series)
2. Report for the content of REACH SVHC list:
The product(s) above contains a substance by more than 0.1wt% per product weight that was published in the 8th update of the REACH
SVHC substances (December 19, 2012).
3. Regarding the safety of the gas sensors (Piezoceramic products):
The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as the main ingredient. It is
chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please note that
risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.
4. Technical product information on the gas sensors (Piezoceramic products):
The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide (PZT) has been
established, and there is no alternative material that can exhibit superior performance than PZT at this moment. Please note that the
piezoceramic is listed as an exempt on RoHS (2011/65/EU) AnnexIII (7c.1).
5. The responsibility of piezoceramic manufacturers:
Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the article 33 of the
REACH regulation

Handling Precautions
Pyroelectric Infrared Sensors should be kept away from indirect and direct sunlight, the headlights of cars, wind, and
exposure to strong vibration and strong shock.
Do not use in water, alcohol ETA, corrosive gas or under sea breeze.
Do not be expose to corrosive substances.
Do not drop or apply any mechanical stress.
The performance of this device can be affected by ESD. Precautions should be used when handling and installing the
sensor. Precision devices such as this sensor can be damaged or caused not to meet published specification due to ESD.
Please note that there is limited ESD protection built-in as the device is optimised for low power consumption and low noise
operation. Human Body Model (HBM), per JS-001: 2,000 V.
Pyroelectric Infrared Sensors should be stored in normal working environments.
Solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long-term
storage.
KEMET recommends that ambient storage conditions are < 30°C and < 60% relative humidity and that maximum storage
temperature does not exceed 110°C. Atmospheres should be free of chlorine and sulfur-bearing compounds.
Temperature fluctuations should be minimized to avoid condensation on the parts.
For optimized solderability sensors stock should be used promptly, preferably within 24 months of receipt.
