Product catalog summary

O2-A3 Oxygen Sensor Specifications

Performance: The sensor outputs between 65 to 82 µA at 22°C with 20.9% O₂. It has a response time of less than 15 seconds for a change from 20.9% to 0% O₂ with a 47Ω load resistor. The zero current is less than 3 µA at 99.999% N₂ at 22°C. Pressure sensitivity is less than 0.1% change in output per 20kPa pressure change.

Lifetime: The output drift is less than 2% over 3 months, and the operating life exceeds 36 months until the output is 85% of the original in 20.9% O₂.

Environmental: Humidity sensitivity is less than 0.7% O₂ change from 0% to 95% relative humidity at 40°C. CO₂ sensitivity is +0.1% change in output per % CO₂ at 5% CO₂. The output at -20°C is 87 to 93% of the output at 20°C, and at +50°C, it is 103 to 107%.

Key Specifications: The temperature range is -30 to 55°C, pressure range is 80 to 120 kPa, and humidity range is 5 to 95% rh continuous (0 to 99% rh short term). The storage period is 6 months at 3 to 20°C in a sealed container. The recommended load resistor is 47 to 100Ω, and the weight is less than 16.5g.

Technical Notes: All sensors are tested under ambient conditions with a 47Ω load resistor unless otherwise stated. Customers should test sensors under their own conditions to ensure suitability.

Performance Data: Figures illustrate the sensor's performance under temperature and pressure changes. The sensor shows predictable and repeatable output changes with temperature and pressure variations. Long-term stability is demonstrated with minimal output shift in response to pressure steps.
