Photoelectric sensor takes a more focused view

Backgrounds are ignored and neither the colour nor material of the object has any major effect.
Idec has expanded its SA1E photoelectric sensor range with a convergent type device that provides a more focused beam than the standard diffuse sensor.
This means the object must reside in a well defined area 5 to 35mm in front of the sensor.
Backgrounds are ignored and neither the colour nor material of the object has any major effect.
Because the convergent type does not employ a moving adjustable lens, its cost is cheaper than a background suppression sensor, but still can be used to perform that function, because of its tight focused beam.
Typical application areas where the SA1E would come into its own would be the detection of integrated circuits mounted on printed circuit boards (ignore the board).
To take advantage of it tight focused range, the small size of the SA1E enables it to be mounted extremely close to production lines.
