SGX Sensors Environmental Sensor IC for Air Quality Monitors

The SGX Sensors SGX‑4OX‑ROHS is an electrochemical oxygen (O₂) sensor IC designed for integration into air‑quality monitoring systems and portable detectors. With a measurement range of 0–25 % O₂ and a response time (T₉₀) of less than 10 seconds, it offers fast detection of oxygen concentration changes. Its robust design supports operating temperatures from ‑40 °C to +60 °C and includes a protected stainless package for industrial environments. The unit is RoHS‑compliant and built for long‑term stability in harsh conditions.

Notable Advantages to Users

• Measurement range 0–25 % O₂ for general air quality applications.
• Response time (T₉₀) less than 10 seconds for near real‑time monitoring.
• Operating temperature range ‑40 °C to +60 °C for wide environmental adaptability.
• Maximum overload capacity of 30 % O₂ supports safety margins in measurement.
• Compact 20 mm industrial standard package (D20 x 16.5 mm) for PCB integration.
• RoHS‑compliant design optimised for modern environmental regulations.

Engineered for Reliable Air Quality Monitoring

The SGX‑4OX‑ROHS is designed with advanced electrochemical sensing technology, providing a stable output drift of less than 5 % over its operational life. It features a low zero‑offset (<0.5 % vol. O₂) and low power bias (‑600 mV typical) for use in battery‑powered systems.
