High performance photoelectric sensors for special applications
November 2014
Sensors & Transducers
Eaton has launched its new E75/E76 series of high performance photoelectric sensors with field-adjustable background suppression and considerably extended sensing range. The key is the IntelliView technology that 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.
In the E75/76 series, Eaton presents 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 easily put the device 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 analogue outputs, the sensors are also provided with two PNP outputs that can be programmed so that they switch at the set distances.
The E75/E76 series are divided into colour, contrast and luminescence sensors. The colour sensors feature a new ‘chromaticity plus intensity’ algorithm, which provides increased sensitivity for colour tone variations and improves the differentiation of greyscale 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. An 8-pin M12 micro connector also ensures analogue signal transmission and a version with a serial (RS-485) interface is also provided for remote communication. The contrast sensors, on the other hand, are ideal for detecting 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.
