A special optical ASIC was specifically developed so that the laser technology could be fitted in the 21 x 14 x 8 mm3 small subminiature housing. The red light laser produces a very precise light spot, which is still so sharp at long distances that even small parts can be reliably detected in the millimetre range – for example the proximity switch with adjustable background suppression can easily detect a wire with a diameter of 0.5 mm at a distance of 60 mm. The very bright light spot, which is clearly visible even in daylight, facilitates alignment and represents absolutely no danger as the sensors are laser class 1.
