Product Description

The KEYENCE FU-50 is a high-precision transmissive fiber optic sensor head designed for detecting minute objects in confined spaces. It features a 2-meter free-cut fiber unit with a 1.0 mm diameter and a top-emitting beam direction, making it ideal for applications requiring minimal detection of objects as small as 0.1 mm. The sensor head has a compact ø1.0 mm diameter and a minimum bend radius of 2 mm, ensuring flexibility in installation. With an ambient temperature range of -40°C to +50°C, it operates effectively in various industrial environments. Weighing approximately 8 grams, the FU-50 offers reliable performance for precise detection tasks.
