Fiber Sensors Overview

A complete fiber optic sensor consists of the amplifer and a fiber optic cable.
The fiber cable is chosen based upon the specific application.
Optex offers more than 80 different cables in both Thru-beam and Diffuse sensing modes.

When to use Fiber optics

confinedareas

The small size and flexibility of fibers allows precise positioning where space is limiited.

High temperature applications

Fiber optic assemblies can tolerate elevated temperatures in some cases as high as 300°F.

High vibration and shock

The low mass of fibers enables them to withstand extreme vivration and mechanical shock.

Noisy environments

FIbers are non-electronic mechanical components, and are completely immune to electrical noise.

Corrosive and wet environments

Special purpose fibers withstand corrosive materials, moisture and even repeated washdown.

Unique target shapes and requirements

Fiber optic sensing heads can be custom-designed and ootimally "shaped" to the physical and optical requirements of a specific application.

1.Amplifiers

The amplifier contains the electronics, transmitting / receiving LED's and is the mechanical interface for the fiber.
The D2RF series amplifiers are sealed and have an IP67 rating.
They can easily be DIN-rail mounted directl on the machine or in a centralized control enclosure.

Fibers

Fiber optic cables are non-electronic, light-transmitting,optical quality glass or plastic strands with cladding.
The fibers serve as a light guide,they are used to transmit the light from and return the light to the amplifier.
Glass fibers are arranged in bundles,while plastic fibers are typically packaged as monofilaments with a protective jacket of polyethylene,PVC,stainless steel braid or other material.
FIber cable sensing tips can have a wide variety of shapes and configurations.

Plastic Fibers

Plastic fibers are best for general purpose use,and where severe flexing like R=2 is required; they can be cut-to-length in the field,and areless expensive than glass fibers.

Features

• ・Inexpensive and easily cut to length during installation.
• ・Bend very easily to fit precisely where you want them.
• ・Special high-flex models withstand flexing.
• ・Special jackets withstand corrosion,impact and abrasion.
• ・Quickly custom-designed and built for your unique applications.

Glass Fibers

Glass fibers are the best choice for challenging environments such as high temperatures, corrosive materials and moisture.

Features

• ・Solve numerous challenging sensing requirements.
• ・For hostile environments such as hiigh temperatures up to 300°C(572°F),corrosive materials,and extreme moisture.
• ・Withstand high levels of shock and vibration.
• ・Inherently immune to extreme electrical noise.
• ・Sheathing is typically stainless steel flexible conduit but can be PVC or other flexible tubing.
• ・Quickly custom-designed and built for your unique applications.
