Product Description

The Keyence FU-98 is a high-performance transmissive fiber optic sensor designed for precise object detection in industrial automation and quality control applications. With a 2-meter free-cut fiber unit and a compact 2.2 mm diameter, it offers exceptional flexibility and ease of integration into tight spaces. The sensor boasts an impressive minimum detectable object size of just 0.2 mm for opaque materials, making it ideal for detecting fine particles or micro-components. Constructed from durable PFA and PTFE materials, the FU-98 is built to withstand harsh environments, featuring an IP67 enclosure rating and a wide operating temperature range of -40°C to +70°C. Its lightweight design (approximately 70 g) and minimal bending radius of 40 mm further enhance its adaptability in complex setups.​
