High performance photoelectric sensors from Eaton
23 November 2014
Eaton's new E75/E76 series of high performance photoelectric sensors offer field-adjustable background suppression and a considerably extended sensing range, thanks to the company's IntelliView technology.
This technology enables a number of new sensing techniques for colour, contrast and luminescence sensing for demanding applications requiring increased precision over large distances in challenging conditions.
The high precision combined with the improved background suppression means the E75/E76 series is suitable for a wide range of applications. The field-adjustable background suppression allows precise detection of objects at distances of up to 190 cm whilst simultaneously suppressing all other background objects.
The E75/E76 photoelectric sensors are divided into colour, contrast and luminescence sensors. The colour sensors feature a new ‘chromaticity plus intensity’ system which provides increased sensitivity for colour tone variations and improves the differentiation of greyscale tones.
This mode is recommended for detecting different colours on the same type of material with a target sensing range of 5 - 45mm from the face of the sensor. Three colour tones can be programmed as standard.
The contrast sensors are suitable for detecting greyscales; for example, positioning marks or differently coloured objects, as well as the detection of targets at a distance of up to 10mm from the sensor face.
Thanks to the sensors’ complementary outputs, they can switch both in response to light or darkness. Objects with reflecting surfaces or luminescent targets can be detected with the E75/E76 luminescence sensor at a distance of 8 - 20mm from the sensor face. This is also suitable for both light and dark conditions.
A user-friendly set-up routine enables both the contrast and also the luminescence sensors to be commissioned and maintained easily. Users can adapt the devices ideally to their applications in only three steps and thus save valuable time during installation or later system modification.
