PRODUCT INFORMATIONTGS 4260 Potentiostatic Electrolysis-type Oxygen Sensor
Features:

Applications:* Lead-free* In 20mm industrial standard packages* Linear output* Quick response to Oxygen* High repeatability/selectivity to O2* Long life
* High impact resistance* Oxygen concentration monitors* Stationary O2 detectors* Portable O2 detectors* Multi-gas detectors

TGS4260 is a potentiostatic electrolysis-type oxygen sensor which has a widemeasuring range and operating temperature range.Its performance is compliant
with the technical requirements of relevant US and European standards.
It is easy to incorporate this sensor in size oriented applications such as portable
oxygen detectors and multi-gas detectors.

Temperature Dependency:

The figure below represents typical response curves when thesensor is placed into 100 vol.% N2 and taken out to the 20.9
vol.% O2 at 20˚C, 50% RH.
It is possible to measure oxygen concentrations with quick
response and high accuracy.

The figure below represents typical temperature dependencyof sensor output and response time measured under various
temperature conditions in ambient air conditions of 20.9 vol.%O2. The temperature dependence of sensor outputs can beeasily compensated utilizing a thermistor. The response is very
fast and has little temperature dependence.

* The specifications shown in the table above are based on the standard test conditions, using
Figaro’s recommended measuring circuit.
*1: When tested under constant operating conditions*2: When tested within the range from -20˚C to 60˚C
*3: Under standard test conditions of 20˚C, 50%RH and 1013 hPa*4: No sudden changes of ambient temperature or humidity

Recommended Measuring Circuit:Please refer to the circuit diagram described in the Product information for the evaluation module EM4260.

Caution:1) If voltage is applied to the sensor, the sensor may be damaged. Please contact us for more details.
2) The sensor pins should not be soldered directly to PC board since the internal structure may be damagedby the heat of soldering, causing electrolyte leakage. Pin sockets should be used for sensor connection.
