Fiber Optic Sensor Mode Settings

To set the mode of a fiber optic sensor, press and hold the MODE button to enter configuration, then use the manual or adjustment buttons to select the desired detection mode, response speed, or threshold settings.Step-by-Step Guide for Keyence FS-N Series SensorsEnter Mode Setting: Press and hold the MODE button for approximately 3 seconds to access advanced settings .Select Response Speed: When “Fine” flashes on the display, press the manual button to choose the response speed. For example, selecting “hSp” sets high-speed mode with a 50 µs response time .Set Detection Threshold: Press the MODE button to move to threshold settings. The display will flash “set” or “setP” for percentage calibration. Use the manual button to adjust the threshold (e.g., 10%–15% of light intensity), .Confirm Settings: Press the MODE button once more to confirm. The current display will show the received light intensity, indicating the sensor is ready for operation .Optional Preset: Use the PRESET button to save commonly used settings for quick recall .Additional TipsPower Mode Selection: Some sensors allow fixing the power mode to “MEGA mode” using a power select switch to ensure consistent light emission .Fiber Connection: Ensure the fiber unit is properly inserted and secured with the fiber lock lever to maintain accurate detection .Calibration: Use the SET button to calibrate sensitivity before adjusting modes, especially when detecting objects of varying reflectivity .Advanced Features: For sensors like the Panasonic FX-500 series, you can also adjust emission power, timer settings, and window comparator modes to fine-tune detection .SummarySetting the mode of a fiber optic sensor involves entering the configuration mode via the MODE button, selecting the desired response speed, detection threshold, and optionally saving presets. Proper fiber connection and calibration are essential for accurate operation. Advanced sensors may offer additional options like emission power adjustment and window comparator modes for precise control .
