Contrinex, Inc.: Flat Fiber Optic Array sensor

Tuesday, April 15, 2008

Contrinex has developed a unique multiple beam, diffuse, flat fiber optic array sensor to solve the problem of capturing, counting and controlling small components produced by modern, high-performance manufacturing machinery.

High exit speeds of parts from production machinery can make product position vary greatly and component count extremely difficult. The new Contrinex LFP-1011-020 flat fiber optic array sensor, specifically designed for this type of application, has a beam spread of 28mm that will detect objects in any position across the broad area of light transmission.

These new sensors can be connected to any Contrinex fiber-optic amplifier creating a very long sensing range of up to 150mm. When used with a 5KHz amplifier, the smallest component passing at high speed can be detected. In addition, by using a blue-light emitting amplifier connected to the fiber instead of the more common red light option, even small black rubber components can be readily detected.

Compared to alternative technologies such as ring or frame sensors, this new fiber concept is extremely simple to apply and at a fraction of the cost.

Each multi-beam head is supplied with 2m of polymer fibers that can be cut to length to enable them to be neatly retained and protected along the optimum path to the amplifier. The wide-vision fiber head is molded from tough PBTP Crastin and is sealed to IP67 for use in aggressive environments.
