KEYENCE FU-67V M6 Parallel Reflective Fiber Unit

KEYENCE FU‑67V is a parallel‑beam reflective fiber unit for non‑contact detection of miniature components and registration marks. M6 threaded stainless steel housing with straight 2 m free‑cut flexible fiber (ø2.2 × 2). R0.5 mm minimum bend radius (Tough‑Flex) for routing in tight spaces, cable carriers and compact machinery. Minimum detectable object ø0.005 mm gold wire. Ambient operating temperature –40 °C to +50 °C. For use with KEYENCE FS‑N, FS‑V and compatible fiber amplifiers (amplifier sold separately). Suitable for ultra‑small object presence detection, high‑speed part counting, precision positioning and quality inspection in electronics assembly, semiconductor manufacturing and automated packaging lines.

Applications:

• Detection of miniature electronic components in pick‑and‑place and surface‑mount assembly

• Small parts presence verification on high‑speed conveyor and sorting systems

• Positioning and alignment in semiconductor wafer handling and PCB manufacturing

• Parts counting and quality inspection in medical device and pharmaceutical production

• Precision positioning in packaging machinery with space‑constrained routing
