KEYENCE FU Series Area Detection Fiber Sensors
With the addition of the new array sensor, the FU Series can now be used in an even wider range of applications.
Application Examples
The FU Series offers versatile detection capabilities:
- Stable detection of targets in varying positions: The sensor reliably detects objects even when their position or orientation changes.
- Positioning a workpiece with eccentricity: The sensor can detect objects that are not perfectly centered.
- Detecting a break in a vibrating wire: Demonstrates detection of fine or moving targets, such as a thin wire.
- Targets with holes: Highlights the sensor's capability to detect objects with gaps or holes.

Array Sensors
Multiple micro-fibers are positioned side-by-side to achieve wide area detection.
Feature 1: Easy Installation
The beam covers a wide area providing easy optical axis alignment and hassle-free installation.
Graph: FU-A10 Parallel Movement Characteristics (Example) - Illustrates the ON/OFF detection range relative to the distance between light projection and reception units.
Feature 2: Excellent Environmental Resistance
Innovative design prevents dust and mist from damaging the unit. Rated IP67.
Flexible Cable
The cable can be placed in any direction to meet installation requirements.
Area Sensors
Light is diffused with a lens to cover a wide area.
Feature 1: Unaffected by Surrounding Objects
The thin beam makes it difficult for surrounding objects to influence the beam. Perfect for use in locations where sensors will be close to many devices.
Graph: FU-E11 Spot Length (Example) - Shows how the effective detection area width varies with the distance between sensors.
Feature 2: Uniform Intensity Distribution
Area sensors can stably sense minute changes in light intensity, making them ideal for small target detection.
Graph: Relationship between received and shielded light (Example) - Depicts how received light intensity changes as an object shields the light beam.
Slit Plate
Small targets can be detected using an optional metal slit plate to narrow the width and thickness of the beam. Available sizes include 30 mm x 0.5 mm and 20 mm x 0.5 mm.
Optical Axis Adjustment Mechanism
Both array and area sensors feature long mounting holes, allowing for optical axis adjustment even after mounting (except FU-11).

Useful Functions when using Area Detection Fiber Sensors
Edge Detection Function
The Edge Detection function detects changes in the intensity of received light. Because of this, it is not easily affected by dirt collecting on the sensors or temperature changes, and is able to provide stable, long-term detection.
Edge Detection Function Diagram: Illustrates how the sensor detects a workpiece by sensing a change in light intensity, showing 'No Workpiece' and 'Workpiece' states.
Attenuation Function
If the numbers on the display don't change as the workpiece passes through the sensor, it is possible that the intensity of received light is saturated. When this happens, minute changes may go undetected. With the FS-V30 Series, the intensity of projected light can be adjusted without changing the response speed.
Attenuation Function Diagram: Contrasts detection without attenuation (where light saturation prevents detecting small changes) with detection with attenuation (where projected light intensity is adjusted to allow detection of minute changes).
