The S80L-Y series, in the sturdy metal housing, offers an innovative laser distance sensors with time of flight measurement. This technology, based on the measurement of the time between the emission and receipt of the laser light pulses, provides a very accurate measurement independent of the target's colour, in the 300 - 4000 mm distance range, with 12 bit elaboration, 0.9 mm resolution and linearity better than 0.3 %.
The class 2 laser emission produces a visible red spot that facilitates the alignment of the sensor with the object to detect. The S80L-Y sensor can be used as a double threshold proximity sensor with high-precision background suppression. A 4-digit display, present on the sensor’s top, visualises the value of the measured distance in mm, as well as all the parameters that can be set with the three push-buttons.
The S80L-Y sensors have two switching outputs, available in both the NPN and PNP models, that can be set at different distances, while the measurement value is supplied on the 4-20 mA analogue output and RS-485 serial interface; the latter can be also used to set all the parameters. Other auxiliary functions are available, such as timing, synchronisation and 5 ms normal or 1 ms fast response time selection.

S81 distance sensor line offers the best solution for all the applications where a cost reduction is requested, without compromising the detection or measurement performances. The class 2 Laser emission and the exclusive time of flight measurement of light technology assure an extreme precision in the distance measurement, with range up to 4 meters. The high resolution is not a limit for the sensing speed, reaching 5 ms response time and 100 Hz switching frequency.
Thanks to only two pushbuttons for different distance thresholds setting, the automatic sensor setting is very easy and accurate for the two independent NPN or PNP outputs. The sensor is available in two different versions: S81-...Y for distance measurement with an additional 0-10 V analogue output, or S81-...M as long distance background suppression proximity with an additional alarm output for received signal problems or dirty lens condition. Moreover the S81-.. Y version offers the possibility to scale the 0-10V analogue output. This feature allows to set the minimum and maximum values of the operating distance and link the minimum and maximum voltage.
Thanks to the compact dimensions and multiple fixing holes with metallic inserts present in standard positions, the sturdy ABS plastic housing can be easily installed everywhere. S81 sensors can find typical applications in automatic material handling and warehousing, in automotive or woodworking industries, as well as for automatic parking or other positioning controls.
