Product Overview
The Keyence FU-35TG is a coaxial reflective fibre unit built for precise, small-spot detection in tight spaces. Its M6 threaded body and stainless steel construction handle harsh industrial environments. The 1 m fibre length cannot be cut, ensuring stable optical performance. This unit detects gold wire as thin as 0.005 mm, making it ideal for micro‑assembly and semiconductor tasks.

Installation Guide
- Mount the M6 threaded body into a standard bracket or tapped hole.
- Keep bend radius ≥ R10 mm to avoid fibre damage.
- Do not cut the 1 m fibre. Cutting changes optical properties.
- Align the coaxial tip with the target for best signal.
- Use stainless housing for washdown or corrosive areas.
Debugging and Maintenance
- Check fibre tip for dust or oil. Clean with lint‑free swab and alcohol.
- Verify amplifier gain settings after installation.
- Inspect bend radius regularly. Sharp bends cause signal loss.
- No user‑serviceable parts inside. Replace if damaged.
Compatibility Notes
Works with Keyence fibre amplifiers (e.g., FS‑N, FS‑V series). The coaxial arrangement suits reflective detection of shiny or micro targets. Not compatible with through‑beam fibre units. Stainless over‑tube protects against mechanical stress.

FAQ
Q: Can I cut the fibre to length?
No. The 1 m length cannot be cut. Cutting ruins optical performance.
Q: What is the smallest detectable object?
0.005 mm gold wire (0.0002 in).
Q: Does it work with any Keyence amplifier?
Yes, with standard Keyence fibre amplifiers (FS‑N, FS‑V, etc.).
Q: What is the warranty?
12 months from date of shipment.
