FU-57TZ Keyence Fiber Optic Sensor – Side View, Tough-Flex, 1 m Free-Cut
Product Overview
The Keyence FU-57TZ is a side-view fiber optic sensor unit. It belongs to the FU series from Keyence. This model uses a ø0.5 mm optical axis for small target detection. Its Tough-Flex design allows a minimum bend radius of R2 mm. The fiber length is 1 m and can be freely cut. It works well in tight spaces and moving parts. The sensor is ideal for industrial automation tasks that need high precision and long-term stability.

Installation Guide
- Mount the fiber unit near the target area.
- Use the side-view direction for tight spaces.
- Keep bend radius above R2 mm.
- Cut the fiber to needed length with a fiber cutter.
- Connect to a compatible Keyence amplifier.
- Adjust sensitivity on the amplifier.
Setup and Maintenance
- Clean the fiber tip with soft cloth and alcohol.
- Check for bends tighter than R2 mm.
- Verify alignment after machine changes.
- Replace if the fiber jacket is damaged.
