Available. The Keyence FU-70TZ is a fiber optic sensor unit designed for precise object detection in industrial automation applications. This built-in lens thrubeam type sensor features a standard M4 nut design, ensuring easy integration into various systems. With an optical axis diameter of 2.3 mm, it effectively detects standard target objects. The 2-meter fiber unit length offers flexibility for installation, and its minimum bend radius of 1 mm ensures durability in tight spaces. Capable of detecting opaque materials with a minimum diameter of 0.1 mm, the FU-70TZ provides high sensitivity for small object detection. Constructed with a SUS303 stainless steel and PBT case, glass lens, polyethylene fiber sheath, and acrylic core fiber, it offers robust performance. The sensor operates within an ambient temperature range of -20 to +50°C and a relative humidity range of 35 to 85% RH, making it suitable for various industrial environments. With an enclosure rating of IP67 (IEC60529) and NEMA Type 4X, 6, and 12, it ensures protection against dust and water ingress. The FU-70TZ has a tightening torque of 0.8 N·m and weighs approximately 22 grams, facilitating easy handling and installation.
