1. APPLICATION

The MICROSONAR proximity sensor works using the ultrasound echo principle and is suitable for measuring

the distances of planar or cylindrical objects.

The measurement can only be accomplished if the space between the unit and the target is free of obstacles

and if the target has good reflection characteristics.

The output of the unit is either an analogue signal depending on the distance, or a distance-controlled switch.
