Expert Frequently Asked Questions

Why is the 1-meter fiber length on the FU-67G explicitly marked as non-cuttable?

The optical core and parallel lens assembly are factory-calibrated and terminated; cutting the fiber cable alters internal light transmission paths and permanently destroys the micro-detection focus.

How does routing the cable below the R10 mm bend radius affect performance?

Exceeding the minimum bend radius of R10 mm causes micro-fractures in the internal glass or plastic fiber strands, resulting in severe light attenuation and intermittent sensor tripping.

What amplifier features should engineers pair with this sensor for optimal gold wire detection?

Field experience recommends pairing the unit with high-speed digital amplifiers featuring fine-tuning sensitivity adjustments and digital threshold clamping to filter out ambient vibration noise.

How can technicians prevent dust accumulation on the M6 threaded tip during operation?

Mounting the sensor behind a filtered air purge or utilizing a protective bracket prevents particulate buildup from blocking the parallel reflective optical path.

What factors guide selection between threaded cylindrical fiber units and flat rectangular variants?

Choose threaded M6 cylindrical housings like this model when direct through-hole mounting into machine plates or brackets is required for fixed optical alignment.
