L-LAS-TB-CL serie laser light curtains for inline measuring tasks Maximum distance 2.000 mm Measurement range 6 up to 98 mm Resolution up to 4 µm up to 1,5 khz scan rate 0-10 V or 4-20 ma analogue output RS232 interface 2 x digital output, 2 x digital input Laser Class 1 General info L-LAS-TB-CL sensors are applied where precise positioning is required, or where the dimensions of an object have to be determined with high accuracy. The series offer various operating widths with a resolution of up to 4 µm. An analog output (voltage output and current output) informs about position and size of the object. Furthermore, 2 digital outputs are available offering information about quality and position of the object. The serial RS232 interface can be used for PLC or PC. Functional principle L-LAS-TB laser line sensors are one-way light barriers. A laser collimator that generates a gap-shaped laser light curtain is used as a transmitter. Greatest importance was attached to keeping the divergence of this laser light curtain correspondingly low, to make sure that parallel laser light is provided. The object is positioned between the transmitter and receiver unit of the sensor system; when the laser light curtain impinges on the object, a shadow of this object is created. The divergence of this shadow also is very small, the shadow is cast almost absolutely parallel. Then the laser light curtain (incl. shadow) impinges on the optical receiver. The task of the optical receiver is to project the laser light curtain onto the respective line sensor. Measurement modes: Edge (left/right) Diameter Gap Centre
