Array sensors

Designed for stable detection, durability, and ease of use

POINT[1] Tough design

The sensor body is protected by a die-cast metal housing, while the inside is filled with epoxy resin, which prevents cracks caused by impact or failure caused by the infiltration of liquid.

POINT[2] Strong cable

The base of the fiber cable (50 mm 1.97") incorporates a stainless-steel jacket. This protects the connection point at the base, which experiences strain when the cable is bent, making it possible to install the sensor in narrow spaces.

POINT[3] Easy optical axis alignment

Benefit of an array fiber

The 60 degree beam aperture of the 30 core fibers results in light expansion over a wide area, which simplifies optical axis alignment.

POINT[4] Slim body

While the FU-A40/A100 covers a wide area, it still maintains a slim body design which allows it to be installed in narrow spaces. (Thickness 5 mm 0.20", Depth 17 mm 0.67")

Area Sensors

Light is diffused with a lens to cover a wide area.

Feature 1: Unaffected by surrounding objects

FU-E11 Spot Length (Example)

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.

Feature 2: Uniform intensity distribution

Relationship between received and shielded light (Example)

Thrubeam area sensors can stably sense minute changes in light intensity making it ideal for small target detection.

Slit plate

Slit plate

Small targets can be detected if the optional, metal slit plate is used to narrow the width and thickness of the beam.

Applications

Confirmation of product ejection

Stably detect workpieces that vary in position.
