Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance

Proximity sensors, all types is a general search form for all proximity sensors and presence detection product areas

Ultrasonic transducers send and receive waves for many types of sensing.

Linear position sensors and switches, ultrasonic, are used for position and displacement sensing, using ultrasonic technology

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas

Collision avoidance sensors use various types of proximity sensors to detect the presence of an object or obstruction
