Our photoelectric distance sensors from the DTECT® Distance Series detect distances, positions and heights with contactless light technology. They output the measured value as a signal for control, regulation or inspection tasks, making them ideal for reliable distance measurement in industrial automation.
These photoelectric distance sensors are convincing both as compact sensor solutions for confined installation situations as well as for long ranges of up to 70 m. Depending on your application, choose from different measurement principles and housing designs to find just the right optical distance sensor.
Selection guide: Which distance sensor do you need?
Our DTECT® Distance series provides photoelectric distance sensors with various measurement principles for different measurement tasks. They are divided into two groups: sensors for highly precise close-range measurements and sensors for longer distances. The choice of the right sensor depends primarily on the required measurement range, the desired precision, and the ambient conditions of the application:
Triangulation sensors for precision close-proximity measurements
Triangulation sensors are the right choice for precise distance measurements at short ranges (up to 1,000 mm). They capture short distances with high repeatability and stable signal quality, making them especially suitable for positioning tasks, height measurements, and control processes in industrial applications.
Sensors suitable for short ranges:
Time-of-flight sensors for long distances
Distance sensors using time-of-flight measurement are suitable for reliable distance measurements over longer ranges (up to 70 m). They detect objects stably even over several meters and are typically used for position determination, object detection, or distance control in conveying, storage, and robotics applications.
