Keyence FU-67G Reflective Fiber Unit for Precision Detection

Product Introduction

The FU-67G is a reflective fiber unit from Keyence. It belongs to the FU series of fiber optic sensors. This model uses an M6 threaded head with a parallel detection arrangement. The fiber unit measures 1 m in total length, and this cable cannot be cut. Moreover, the straight-shaped head simplifies mounting in tight spaces. As a result, the FU-67G suits high-precision presence and position detection tasks.

Technical Specifications

The FU-67G carries an M6 size designation for direct panel mounting. Its detection arrangement is parallel, which improves repeatability for small targets. Specifically, the unit detects gold wire with a diameter of just 0.005 mm. This makes it ideal for micro-component inspection. 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, installers must route the cable carefully to avoid damage.

Mechanical and Environmental Parameters

Weight for this unit is approximately 29 g. The FU-67G operates from -40 to +50°C. Additionally, this wide range supports both cold storage and standard factory floors. The stainless bend radius protection adds mechanical durability. Besides, the straight head shape allows flush mounting against flat surfaces. Meanwhile, the parallel arrangement keeps the emitter and receiver aligned for stable signals.

Installation Guide

First, mount the M6 head through a standard threaded hole. Next, tighten the locking nut without over-torquing the body. 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, run a sensitivity calibration on the target. Proper alignment ensures reliable detection of the 0.005 mm gold wire.

FAQ

Q1: Can I cut the FU-67G fiber cable?
A: No. The 1 m fiber unit length cannot be cut. Cutting would destroy the optical path.

Q2: What is the smallest detectable object?
A: The FU-67G 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-67G weigh?
A: It weighs approximately 29 g. The light weight reduces strain on mounting points.
