Eaton (USA) - Power management company Eaton is launching its new E75/E76 series of high performance photoelectric sensors. Sensors with field-adjustable background suppression and a considerably extended sensing range are also being released for the first time. The key to this is the IntelliView technology. It enables a number of new sensing techniques for colour, contrast and luminescence sensing for particularly demanding applications requiring increased precision over large distances in challenging conditions. The high precision combined with the improved background suppression make the E75/76 sensor series into a flexible, high performance solution for a wide range of applications. Through the small number of sensing errors, the devices contribute even in the most difficult environments to increasing the productivity of machines and plants.
In the E75/76 series, Eaton is presenting a photoelectric sensor with field-adjustable background suppression. It detects objects precisely at a distance of up to 190 cm and at the same time suppresses for example container edges. Besides the broad application range, the sensor stands out on account of its simple installation. This enables users to put the device easily into operation and adapt automatically to the individual requirements at the site of installation.
Eaton has also developed laser distance sensors with increased sensing depth, especially for the E75/E76 IntelliView series. These distance sensors output a signal from 0 - 10 V which changes within the operating range proportionally to the distance between the face of the sensor and the target. The integrated class II laser detects objects in a range between 0.3 and 4 m. In addition to analog outputs, the sensors are provided with two PNP outputs that can be programmed so that they switch at the set distances.
Eaton's series E75/E76 photoelectric sensors are divided into colour, contrast and luminescence sensors. The colour sensors feature a new “chromaticity plus intensity” algorithm. This provides increased sensitivity for colour tone variations and improves the differentiation of grayscale tones. The “chromaticity plus intensity” mode is recommended for detecting different colours on the same type of material with a target sensing range of 5 - 45 mm from the face of the sensor. Three colour tones can be programmed as standard. An 8-pin M12 micro connector also ensures analog signal transmission. A version with a serial terminal (RS 485) is also provided for remote communication. The contrast sensors, on the other hand, are ideal for detecting grayscales (e.g. positioning marks) or differently coloured objects, as well as the detection of targets at a distance of up to 10 mm from the sensor face.
Thanks to the complementary outputs, they can switch both in response to light or dark. The 4-pin M12 micro connector integrated as standard also simplifies integration in existing installations. Objects with reflecting surfaces or luminescent targets can be detected with the E75/E76 luminescence sensor at a distance of 8 - 20 mm from the sensor face. This is also suitable for both light and dark conditions. A user-friendly setup 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 the installation or later system adaptions.
Eaton offers a wide range of sensors worldwide for maximum precision and virtually any application. Besides mechanical limit switches, the sensor manufacturer offers around 1,000 different types of inductive, photoelectric and capacitive sensors. The sensors are used primarily in machine building, in packaging technology, the food and beverage industry and in material handling.
