KEYENCE FU-40 2 METER FIBER OPTIC SENSOR FU40

Description:

The Keyence FU‑40 2 Meter Fiber Optic Sensor is an optical sensing device that uses fiber‑optic cables and an amplifier to detect objects, changes in surface conditions, or position without direct contact. Installed in automation systems where tight spaces, small targets, or difficult detection environments make standard photoelectric sensors impractical. Maintenance teams, system integrators, and automation technicians use this fiber optic sensor for replacement, retrofit, and system upgrades to provide dependable, high‑speed detection in industrial applications.

Applications:

The Keyence FU‑40 2 Meter fiber optic sensor is used in manufacturing automation, packaging lines, conveyor systems, robotic cells, and inspection stations to detect small parts, presence, surface changes, or motion where space constraints or challenging surfaces exist. Keyence fiber optic sensors deliver reliable non‑contact detection in environments requiring high precision and noise‑immune sensing for PLCs and machine control logic in automated manufacturing and processing systems.
