Keyence FS-N11P FS‑N Series Fiber Amplifier Cable Type Main Unit PNP

Keyence FS‑N series FS‑N11P is a digital fiber optic amplifier for non‑contact detection of small parts, registration marks, and transparent objects. Cable‑type main unit with a single PNP open‑collector output and built‑in red 4‑element LED. High‑speed response down to 50 µs (HIGH SPEED) and high‑power output (MEGA mode) support both fast and challenging detection tasks. One‑push APC (Auto Power Control) compensates for LED degradation and fiber bending to maintain consistent detection.

Applications:

• Small part detection in high‑speed assembly, packaging and semiconductor equipment

• Positioning and presence control in automated pick‑and‑place systems

• Quality inspection and counting in electronics manufacturing

• Transparent object detection with Keyence fiber optic cables

• Registration mark detection on continuous webs
