Data sheet for O2S Probe Style oxygen sensors detailing features, specifications, electrical connections, and ordering information.
The O2S Probe Style oxygen sensor series offers zirconium dioxide sensing elements, non‑consumption technology, and an integral heating element. Available in 80 mm, 220 mm and 400 mm probe lengths, the sensors operate without temperature stabilization or reference gas and provide a linear output signal.
Key specifications include an oxygen pressure range of 2–3000 mbar, heater supply voltages of 4 V DC (Porous Lid Cap) or 4.35 V DC (Full Porous Cap), and permissible gas temperatures from –100 °C to 250 °C (or up to 400 °C for high‑temp versions). Electrical connections use a Molex 5‑pin connector, and detailed ordering information is provided for each model variant.

The sensor measures oxygen pressure from 2 mbar up to 3000 mbar.
It requires a 4 V DC supply with a tolerance of ±0.1 V.
The sensor can operate between –100 °C and 250 °C.
A 5‑pin Molex connector is used, with pins for pump, common, heater, and sense.
