This is the Kobelco Nox 24V Sensor, part number VY129G0119800. A NOx sensor measures nitrogen oxide in the exhaust gas and sends that reading to the engine control system. Order by the exact part number, because sensors that look alike can differ in ways that only the parts book will show.

In general, a NOx sensor reads the nitrogen oxide content of the exhaust and reports it to the engine or emissions control system. The control system uses that information to monitor how the exhaust aftertreatment is performing.
Common signs include emissions-related fault codes, warning lamps on the monitor, and reduced engine performance flagged by the control system. These symptoms can have other causes, such as wiring or connector problems, so follow the diagnostic steps in the machine's service manual before replacing the sensor.
Have the part number (VY129G0119800), the machine model and serial number, and the quantity you need. Any fault codes you are seeing can help the parts team as well.
