FD-F8Y is a reflective-type fiber optic sensor from Panasonic SunX, engineered for liquid-level detection with a 6 mm diameter fiber head and a 2 m free-cut fiber cable. The top-view beam arrangement uses a no-sleeve fiber with free-cut capability, and supports an allowable bending radius of 40 mm for the protective tube and 15 mm for the fiber. The unit is IP68 rated and operates from -40 °C to +125 °C, with the fiber type described as contact-type liquid level sensing and the sensing mode as reflective, making it suitable for liquid-level sensing and liquid-leak detection in demanding environments.
