The Panasonic FX-311 series fiber sensor is designed for applications requiring precise and reliable sensing. It features a 12-turn potentiometer with a visible indicator and red backlight for easy adjustments, even in dark environments. The sensor's innovative “four-chemical LED” significantly reduces sensitivity drift over time, minimizing maintenance and ensuring stable operation. A convenient “assist function” provides visual feedback during sensitivity adjustment, simplifying the setup process. The FX-311 is available in various configurations, including NPN and PNP output options, and is suitable for a wide range of industrial applications.
