OTC LASER TRACKING SENSOR FD-QF

High-Speed Blue Laser Technology • Gloss-Resistant Tracking

The OTC DAIHEN FD-QF is a cutting-edge 2D blue laser-based weld seam tracking sensor engineered to drastically enhance robotic accuracy and cycle efficiency. Utilizing short-wavelength **Blue Laser** technology, this sensor delivers exceptionally rapid joint detection even when operating on highly reflective or polished surfaces such as aluminum and stainless steel.

Key Features

Industry-best detection speed: Identifies the exact joint position within an ultra-fast processing time of approximately 0.3 seconds.
Ultra-High Accuracy: Provides an outstanding structural tracking precision of up to ±0.2 mm, surpassing conventional seam tracking sensor baselines.
Gloss-resistant Performance: Advanced Blue Laser optical filtering guarantees highly stable detection and scanning on mirror-finish or high-gloss materials.
Streamlined Setup: Integrates natively with the FD-series teach pendant software environment, eliminating any requirement for external standalone PCs.
