The AFM9 is a universal wideband lambda sensor controller that adds lambda, air-fuel ratio, and oxygen-measuring capability to your company’s engine controller. Just plug or solder the compact AFM9 to your controller’s circuit board and wideband sensor information is available through a SPI interface and an analog signal.
The AFM9 uses a wideband sensor ASIC (application-specific integrated circuit), support circuitry, and control algorithms that have proven themselves in hundreds of thousands of OEM applications. Now this technology and experience can be used in your OEM applications. Sensor identification, start-up, control, filtering, calibration, diagnostics, and shut-down are all controlled by the AFM9. All your controller has too do is read the SPI interface or analog output. The AFM9 will work with any NTK (NGK Spark Plug), Bosch, or Delphi wideband sensor.
