Keyence FU-57TZ Fiber Optic Sensor for Side Detection
Product Introduction
The FU-57TZ is a fiber optic sensor from Keyence. It belongs to the FU series of fiber units. This model uses a side-emitting beam direction for tight installation angles. Its optical axis diameter is ø0.5 mm for standard targets. Meanwhile, the fiber unit is 1 m long and free-cut, so users can trim it to length. As a result, the FU-57TZ fits confined spaces where standard heads cannot reach.
Technical Specifications
The FU-57TZ features a ø0.5 mm optical axis diameter. Its beam emits from the side rather than the tip. The fiber unit length is 1 m, or 39.37 inches, and it is free-cut. Additionally, the fiber unit diameter is ø1.0 for flexible routing. Specifically, the minimum bend radius is R2 mm thanks to Tough-Flex construction. This sensor detects objects with a diameter of just 0.005 mm. Therefore, it handles micro-part detection with ease.
Mechanical and Environmental Parameters
Weight for this unit is approximately 5 g. The FU-57TZ operates from -40 to +50°C. Besides, this range covers cold storage and normal factory conditions. The Tough-Flex fiber withstands tight bends without breaking. Meanwhile, the small ø1.0 diameter reduces routing strain in robotic joints. In addition, the side-emitting head saves vertical space above the target.
Installation Guide
First, position the side-emitting head beside the target. Next, secure the fiber with brackets or adhesive mounts. Then, route the free-cut fiber with a bend radius above R2 mm. After that, trim the fiber ends to the required length. Finally, connect to a compatible Keyence amplifier and calibrate sensitivity. Proper alignment ensures reliable 0.005 mm object detection.

FAQ
Q1: Can I cut the FU-57TZ fiber cable?
A: Yes. The 1 m fiber unit is free-cut. Trim it to the length you need.
Q2: What is the minimum bend radius?
A: The minimum bend radius is R2 mm. Tough-Flex construction allows this tight bend.
Q3: What is the smallest detectable object?
A: The FU-57TZ detects objects with a diameter of 0.005 mm. This suits micro-part sensing.
Q4: Which direction does the beam emit?
A: The beam emits from the side of the head. This helps in space-limited installations.
Q5: How much does the FU-57TZ weigh?
A: It weighs approximately 5 g. The low weight suits moving axes and robots.
