With self-contained fiber-optic sensors available in housings as small as 30 × 30 × 15 mm, and several models of small DIN-rail mounted amplifiers that accommodate multiple-sensor applications, the Contrinex range is highly versatile. A choice of synthetic optical fibers with impressively low attenuation rates for general use or glass optical fibers for high ambient temperatures and aggressive environments provides options for even the most demanding applications.
Customers requiring intrinsically-safe photoelectric sensors with DIN-railmounted electronics need not look beyond the Contrinex 3060 series of fiber-optic amplifiers. Packed with functionality in a Crastin® molded-resin housing measuring only 31 × 60 × 10 mm, every model combines ease of set-up with market-leading features. With switching times as low as 0.1 millisecond, 3060 fiber-optic amplifiers are ideal for sensing fast-moving targets in demanding environments, including robotics, precision handling systems and printed circuit board production.
Distance setting is accomplished either by adjustment of a multi-turn potentiometer or by use of a teach-in function with manual fine adjustment; an optional digital display (model 3066) is also available. Using blue-light sources (model 3360), detecting glass and other materials with similar absorption spectra is possible at distances up to 100 mm.
Fiber-optic sensors are common in explosive environments or in the presence of strong electromagnetic fields – in these areas, sensors that rely on electrical signals may present a risk of explosion or fail to operate correctly. Contrinex manufactures world-class fiber-optic sensors and amplifiers that not only meet these needs, but also present a highly practical means of sensing in confined spaces. With bend-radii as small as 2 mm, reliable, accurate sensing is possible even in the most inaccessible areas.
