The Keyence FU-E40 is a transmissive area-type fiber optic sensor unit designed for wide-area detection in industrial automation applications. This fiber unit features a 40 mm wide optical detection area, making it suitable for detecting objects with varying positions or complex shapes. The sensor utilizes a through-beam configuration with an optical axis diameter of 40 × 3 mm, enabling reliable detection across the sensing area. The FU-E40 comes as a pair of identical fiber units with a 2-meter free-cut fiber cable, allowing flexible installation and custom cable routing. Constructed with durable materials including polybutylene terephthalate housing and acrylic core fiber with polyethylene sheath, the unit offers excellent environmental resistance. It operates across a wide temperature range and features a minimum bend radius of R2 mm for Tough-Flex cable routing in confined spaces. The sensor is compatible with Keyence FS-V30 and FS-N40 series fiber optic amplifiers for complete detection systems in manufacturing and automation environments.
