Light sensor

*

This is a further development of the light barrier. Though the light sensor is always aligned by TrySim along the X, Y or Z axis. Then it surely captures all dynamics crossing its ray.

As long as your sensors only have to capture right/left, forward/backward, up/down the light sensor is easier to use. But if you absolutely have to look obliquely you should better use a light barrier.

The light sensor has proved helpful, for example, if you want to capture very thin dynamics, because the light barrier is standardized in such a way that it is only sensitive in one point of the middle of the ray. If these thin dynamics (e.g. board) are located outside the only sensitive point of a light barrier can't be recognized suddenly. This problem can't arise in using light sensors.

In huge machine (>500 I/Os) with many dynamics the exchange of light barriers against light sensors can make a substantial contribution to reducing computation time. However, please contact us prior to such modifications. www.trysim.de

Unfortunately, the simplified calculation rule of the light sensor does not work in recording turnable dynamics. That is why you can enter the number of points at the light sensor that are supervised along the ray. This number you can adjust within 1-19 has _only_ an impact on registration of turnable dynamics. Please ignore this parameter if you don't have any turnable dynamics in your machine.

ATTENTION! On the other hand, if the light sensor itself is turned it will not work anymore. In this case please use the light barrier.
