Motion Control Proximity Dimension-Level
 

Proximity Sensing applications include the detection of the presence, absence or position of a person or other object of interest. The sensor will detect the closest object within it's beam pattern that reflects ultrasound. Senix® Ultrasonic Sensors incorporate a high sensitivity transducer to detect most small and weak-reflecting materials (some reflection is required) such as clothing and some woven and non-woven materials. Small object distances can be measured as close as 5 cm (2 inches), or closer if only their presence/absence is required. The maximum range is about 11 meters (37 feet). Detection of objects at longer ranges requires that the target be larger and oriented to reflect ultrasound back to the sensor. For example, a person can be typically detected reliably at distances up to about 6 meters (20 feet).

NOTE: Senix® Ultrasonic Sensors should not be used in any application where personal safety or hazardous materials are involved!

People Detection / Kiosks

 

 A common application is the detection of the presence or absence of people, generally when they approach a kiosk or information display. The display can be activated or changed based on the sensor input. One advantage of Senix® sensors in these applications is that the distance of the person could be used rather than just their presence or absence, permitting a different response if the person is arriving, stopped or leaving.

Presence / Absence

Objects can be monitored for their presence, absence or position. One advantage of Senix® sensors is they are not affected by the object's color or any other optical characteristic such as reflectivity, transparency or opacity. Sensors can be used in the dark and are not affected by ambient light.

Obstacle Avoidance

If you can detect an object, you might want to avoid it! Senix® sensors are used in robotics and guided vehicle applications to maintain proper distances and assist with navigation.

Sort / Select

Depending on the position of the sensor relative to the object being measured, Senix® sensors can be used to discriminate objects by height or size. This could involve selecting boxes on a conveyor belt, rejecting out-of-dimension objects, or similar applications.
