  • GV Series Laser Sensors

WOODCLIFF LAKE, N.J., Jan. 2, 2008 -- The new GV series of digital CMOS laser sensors from Keyence Corp. of America use a new Datum algorithm to detect certain targets more reliably than conventional sensors can, according to the manufacturer. The GV, an optical triangulation sensor, excels in detecting shiny targets with multiple reflections as well as light-absorbing materials such as black rubber.

Designed for automatic, in-line sensing applications, the GV detects target presence or absence based on surface characteristics or target height and provides a GO/NG output. Up to four sets of sensors and amplifiers can be utilized for each application. The GV series includes four IP67-rated sensor head models with detection ranges of 45 mm (1.77 in.), 130 mm (5.12 in.), 450 mm (17.72 in.) and 1000 mm (39.37 in.).

This enables the sensor to receive a greater quantity of light, resulting in highly stable detection and faster response speeds. The GV Datum algorithm utilizes an innovative calibration technique in which the received light waveform pattern from a target or background is used to set upper and lower received light limits. Detection is stable even when the targets are moving or the background is unstable causing conditions where the target-to-sensor distance varies, the company said.

Three detection modes are selectable on the GV amplifier: An edge hold mode (patent pending) detects sudden changes in workpiece height, a surface detection mode detects the nearest surface, and a clamp function which ignores targets too close to the sensor head.

The GV series amplifier panel incorporates a dynamic, multisegment bar LED display. The number of individual LED bars that display red or green confirm the instantaneous detection status. Bars display green when detection is within limits; the number of red bars increase when detection is nearing or is out of the calibration range.

A precisely defined series of steps that describes how a computer performs a task.
A device that enlarges and strengthens a signal's output without significantly distorting its original waveshape. There are amplifiers for acoustical, optical and electronic signals.
Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
