FU-67G Keyence Reflective Fiber Unit, M6 Micro Detection Sensor Head

FU-67G Keyence Reflective Fiber Unit for Tiny Target Detection

FU-67G is a reflective fiber unit from Keyence. It uses a compact M6 size and a parallel detection layout. The 1 m cable cannot be cut. A stainless steel build gives it a small R10 mm bend radius. It can sense a gold wire just 0.005 mm wide. This makes it ideal for fine positioning and micro part checks.

Expert Review

The FU-67G shines when targets are very small. A 0.005 mm gold wire is a hard test for most sensors. This unit handles it. The M6 thread fits tight spaces. The parallel layout helps in narrow gaps. The stainless build resists wear and heat.

The fixed 1 m cable is a limit. You cannot cut it to fit. Plan your routing first. The wide heat range from -40 to +50 degrees C suits cold rooms and hot lines. For micro detection, this head is a top pick.

Manager’s Insight

This fiber unit sells to electronics, semiconductor, and precision assembly teams. Buyers want tiny spot detection and long life. Stock moves fast when a line needs fine sensing. Keep a few units ready. Pair them with a good Keyence amplifier for the best result.

Best Fit Applications

• Micro part presence checks
• Wire and thread detection
• Semiconductor and electronics assembly
• Small hole and edge sensing
• Tight spaces with M6 mounting
• Cold rooms and hot production lines

FAQ

Can I cut the fiber cable to fit my machine?

No. The 1 m length is fixed. Plan your layout before you install it.

How small an object can it detect?

It can sense a gold wire with a 0.005 mm diameter.

Does it need a separate amplifier?

Yes. It works with a Keyence fiber amplifier. Match the model to your setup.

What is the smallest safe bend?

Keep the bend at R10 mm or more. Sharper bends can damage the fiber.

Will it survive cold or hot areas?

Yes. It works from -40 to +50 degrees C without condensation issues.

How do I order and what support do I get?

We offer a 12-month warranty. Orders leave in 12-24 hours by FedEx, UPS, or DHL. Reach us at sales@powergearx.com or +86 18030005825.

Buying Guide

• Check your amplifier matches this fiber unit.
• Plan cable routing before you buy.
• Confirm the M6 size fits your bracket.
• Keep bends at R10 mm or more.
• Order a spare for critical lines.
• Ask for a tested unit and clear photos.
