Laser proximity sensor with background suppression

"Detect all" is one of the operating modes of SensoPart's newly introduced BGS sensor, and it is a function that its new addition to the range takes quite literally, according to the company. It states that the new FT 55-RLHM can cope with any type of target object, whether it is brilliant metal, transparent or black against a black background. The sensor is said to respond to all deviations from a given reference, such as a change in object distance, a different surface finish or even a deflected laser light beam. In this mode the sensor has no blind zone: that is, objects are detected from 0mm. Even small parts are said to be reliably identified within the defined detection range, including objects at acute angles.

The FT 55-RLHM not only uses the distance value but can also integrate the energy remitted from the target object as part of the detection process. Also, as a result of a high level of detection efficiency, the new sensor can also be used to check the stack height of parts and identify multiple layers: for example when stacking cardboard packaging. Here the sensor automatically detects the presence of either too many or too few layers.

Maximum operating range with minimum hysteresis are said to be further highlights, and excellent object detection is the result of the new sensor's wide operating range of up to 1m. SensoPart says that the switching hysteresis is simultaneously minimal, so that even the tiniest objects can be reliably detected from a long distance - for example, a sheet of paper at 250mm. The determined object distance is shown on an integrated display screen, which facilitates the set up of the application.

In addition to user-friendly operation via soft keys, the sensor also offers two independent switching outputs, as well as a digital IO-Link interface, something the supplier is keen to highlight in this price category. It also comes with additional functions for the configuration of switching outputs, such as switch-on/switch-off delays. This range of functions, combined with a high-quality metal housing and non-hazardous Class 1 laser, makes SensoPart's new FT55-RLHM laser proximity sensor with background suppression suitable for a diverse range of industrial automation applications.
