Keyence FU-35TG Reflective Fiber Unit for Coaxial Detection
Product Introduction
The FU-35TG is a reflective fiber unit from Keyence. It belongs to the FU series of fiber optic sensing products. This model features an M6 threaded head with a coaxial detection arrangement. The fiber unit measures 1 m in total length, and this cable cannot be cut. Moreover, the threaded shape allows secure screw-in mounting. As a result, the FU-35TG suits precise detection of tiny targets in compact machinery.
Technical Specifications
The FU-35TG uses an M6 size for standard threaded mounting. Its coaxial detection arrangement keeps the emitter and receiver on the same optical axis. Specifically, the unit detects gold wire with a diameter of just 0.005 mm. This makes it excellent for micro-component and wire sensing. The fiber unit length is 1 m, or 39.37 inches, and users cannot cut it. Furthermore, the minimum bend radius is R10 mm with stainless protection. Therefore, careful cable routing is essential for stable performance.
Mechanical and Environmental Parameters
Weight for this unit is approximately 32 g. The FU-35TG operates from -40 to +50°C. Additionally, this wide range supports cold storage and standard production floors. The stainless bend radius protection improves mechanical durability. Besides, the threaded head shape enables rigid, vibration-resistant mounting. Meanwhile, the coaxial layout reduces detection blind spots on shiny surfaces.
Installation Guide
First, drill and tap a standard M6 threaded hole at the sensing point. Next, screw the head in and tighten the lock nut gently. Then, route the 1 m fiber cable with a bend radius above R10 mm. After that, connect the fiber ends to a compatible Keyence amplifier. Finally, perform a sensitivity calibration on the actual target. Proper setup ensures reliable detection of the 0.005 mm gold wire.

FAQ
Q1: Can I cut the FU-35TG fiber cable?
A: No. The 1 m fiber unit length cannot be cut. Cutting would break the optical path.
Q2: What is the smallest detectable object?
A: The FU-35TG detects gold wire with a diameter of 0.005 mm. This suits micro-part sensing.
Q3: What is the minimum bend radius?
A: The minimum bend radius is R10 mm with stainless protection. Keep routing above this value.
Q4: What is the operating temperature range?
A: The unit works from -40 to +50°C. This covers most industrial environments.
Q5: How much does the FU-35TG weigh?
A: It weighs approximately 32 g. The light weight reduces strain on mounting points.
