Why Stealth Technology is Better over Long Distances
A major problem with common 2-laser/2 detector shaft systems is trying to use them on long-distance applications. As the illustration on the left shows, when you try to make moves to the motor, the long distance makes the readings very sensitive to angular changes. For example, a tiny angular movement of 0.5 mm/100 mm at 3 m will cause the laser beam to move in offset by 1.5 mm!
This makes aligning the motor's offset value very difficult to do especially for the horizontal axis. With our uni-directional laser technology, however, angular moves to motor do not move the laser beam at all and therefore do not affect the offset values! This means aligning the motor is amazingly easy, especially over long distances.
