2 INTRODUCTION LAS laser sensors cover measurement ranges from to 800 mm. The integrated microcontroller delivers an accurate output signal, which is proportional to the detected distance. External analysers to evaluate the signals are not required. Reliable operation, independent of color or other influences of the surface, is ensured by sophisticated electronic elements integrated in the system. The small visible laser spot allows a simple and precise orientation of the sensor. Distances to rough surfaces can be measured by using a fine laser line instead of the spot. MEASURING PRINCIPLE The triangulation principle is basic for this measurement method. The laser beam in the form of a small spot arrives on the surface of the target, while the detector of the system captures its position. The distance itself is calculated by means of the change of the angle. Achievable resolution and accuracy are therefore influenced mainly by the distance d: In proximity of the sensor, a large angular change a can be obtained, whereas larger values result in a smaller angle a, thus in reduced accuracy (see drawing). A photo diode array integrated in the sensor represents the receiver, high speed versions use a PSD element. The receiver is directly coupled to a microcontroller, being part of the system. This microcontroller analyses the light distribution on the element, calculates the exact angle and out of it the distance to the object. The calculated distance is either transferred to a serial port or alternatively is converted to a proportional output current. The microcontroller guarantees a very high linearity and accuracy. The combination of photo diode array and microcontroller allows a suppression of interfering reflections and ensures a reliable results even on most critical surfaces. Blind range Measurement range The sensor automatically adapts to the surface colour by a change of its internal sensitivity. This way influences due to the target colour are nearly excluded. An integrated digital output is activated whenever the sensor does not receive enough light (pollution signal), or if no object within the measuring range can be detected at all. a a d d INSTALLATION Spot laser The object is sampled by a focussed laser beam. This version is the most preferred within the LAS series. Line laser The laser beam is expanded to a fine line, by means of a deflection unit. Typical applications for sampling a target with a line laser are the position or thickness measurements of objects with rough, uneven, porous or interrupted surfaces. Teachin function The desired range can conveniently be adapted within the maximum measurement range by means of the teachin line or button. The analog output has its full stroke within the teached range. The default configuration uses the maximum measurement range. A separate description of the teachin procedure is available upon request. Installation The first condition for a successful distance measurement is the absence of any obstruction in the light path, as shown in fig.. The receiver optics must be able to detect the light spot directly (fig. and ). () () () For highly polished or mirrorlike objects it is important to keep the direct reflection away from the detector. In these cases, it is recommended to slightly tilt the sensor (fig. ). WRONG Optimum results are obtained by transverse installation of the sensor with respect to the target movement (fig. 5). For triangulation sensors, there is a simple rule, that the distance between sensor and target should be as small as possible. The smaller the working range the better the linearity and accuracy. Electromagnetic compatibility: The sensor must correctly be grounded, a shielded cable is recommended. Cleaning of the laser window ) dry cleaning with a soft brush ) cleaning with a dry, soft, antistatic cloth ) wet cleaning with clear water, approx. 0 degree Celsius, if necessary with a little mild soap. Please do NOT use window cleaner!! () (5)

In both cases the analog output signal is ma / resp. 0 V. The sensor has no internal hold function to bridge missing measurement signals. Therefore it may happen in critical applications (extremely bright surfaces) that the output shortly drops to ma / resp. 0V, when the measurement signal gets lost. By checking the status of the alarm output before making a measurement, this false output signal can be identified.
