Operating principle of position sensors
Position sensors are used to detect objects. Depending on the material to be detected, different sensors are used to detect objects reliably and without contact. Inductive sensors can detect metal objects. The detection range depends on the design of the sensor. Capacitive sensors are used for object detection - irrespective of their material characteristics. In contrast to the inductive sensors it is not a change in the magnetic field that is evaluated for position determination but the change in capacitance in an electrical field is used. In applications where large detection zones are needed ultrasonic sensors with long ranges are used. In addition photoelectric sensors such as light barriers or diffuse reflection sensors are used for the detection of objects in the running position process.
Industrial position determination
The advantage of the sensors is the non-contact detection of components. Thanks to the mechanical compatibility, old position switches can for example easily be replaced by sensors.
Due to their wide range of applications and easy mounting the sensors are used for numerous applications in industry such as:
- Food industry
- Packaging technology
- Mechanical and plant engineering
- Paper production
- Plastics industry
Huge selection of position sensors
Automation24 offers a number of different sensors. From inductive sensors and capacitive sensors to ultrasonic sensors and light barriers all common versions are listed. Depending on the type of the selected sensor the design or type of installation can be selected.
A decisive criterion for the selection of a sensor for position detection is the output function. The user determines the function that the sensor should trigger. Capacitive, inductive and ultrasonic sensors are often used as normally open. For light barriers the output function is called light-on or dark-on mode. Photoelectric systems also provide a number of different function principles such as through-beam, retro-reflective and diffuse reflection sensors.
At Automation24 you find a large selection of position sensors at very favourable prices. Automate your application with the suitable position sensors now.
