Industrial W10B16A-O2SENSOR-2X-UPSTREAM-DOWNSTREAM Oxygen Sensor

Industrial W10B16A-O2SENSOR-2X-UPSTREAM-DOWNSTREAM Oxygen Sensor is a two-sensor set (upstream and downstream) of zirconia O2 sensors for automotive engine management, providing exhaust oxygen level feedback before and after the catalytic converter to help regulate air-fuel ratio. Suitable for gasoline and diesel vehicles with OBD-II emissions systems, it enables real-time fuel-mixture adjustment and catalytic converter monitoring. Key specs include an operating temperature up to ~900°C, a 0.1–0.9 V switching output, an integrated heater for fast warm-up, a stainless steel body with a ceramic sensing element, and a multi-pin sealed automotive connector with typically M18 x 1.5 threads. Common replacements include Denso OEM-equivalent upstream/downstream sensor sets, Bosch O2 sensor pairs, and NTK/NGK oxygen sensor kits for vehicle-specific applications.
