Ultrasonic Sensors

Ult­ra­so­nic sen­sors are su­itab­le for de­tec­ting trans­pa­rent, dark, glossy, ref­lec­ti­ve or po­ro­us sur­fa­ces. They can de­tect ob­jects or liquids des­pi­te the pre­sen­ce of dirt, dust, mist or extraneous light. The me­asu­red va­lu­es are de­ter­mi­ned by trans­mit­ting and re­ce­iving ult­ra­so­nic waves which are out­put as vol­ta­ge or via IO-​Link.
