In the field of photoelectric sensors, Baumer plays a leading technical role in the solution of demanding detection tasks. In the past few years, we have repeatedly managed to set new standards, for example with the smallest diffuse sensor with background suppression, the smallest programmable photoelectric sensors or the first light barrier without a separate reflector/receiver. We are also world market leaders in the field offor the printing and packaging industry.
How do photoelectric sensors work
Photoelectric sensors are non-contact electronic sensors. They detect objects using optical radiation – thanks to different technologies, in part even independent of material or color.
- High resolution
- Very short response times
- Easily visible light dot
- Variety of different beam shapes and light sources to increase application range
- Objects can be detected either dependent on their materials, or independently thereof
- High measuring/sensing range
The sender of the photoelectric sensor emits a visible or infrared light beam. The light package is reflected back to the receiver in the sensor by either a reflector or an object, or it is sent directly to a seperate receiver. The received light is evaluated by the integrated electronics and depending on the sensor type, either digital or analog information is then issued at the output.
When using photoelectric object detection one can chosse between two different physical principles: diffuse sensors and light barriers. Likewise, two different principles are used for distance measuring: triangulation and time of flight.
qTeach is an easy to operate, wear-free teach method for Baumer sensors. Sensors with qTeach are adjusted by touching them with any ferromagnetic tool instead of using the conventional teach button. The teach spot that must be touched is marked with a recess and the inscription “qTeach”.
Benefits of qTeach:
- Easily accessible and operable
- Sensor can be taught directly throughout the whole service life
- No weak spot compromising the impermeability of the sensor
- No wear, due to no moving parts
FAQ about qTeach:
Can I use any tool?
Yes. With regard to functional reliability we recommend a slotted screwdriver size 3 or bigger.
Does a ferromagnetic fixation of the sensor influence qTeach negatively?
No. It is important, however, that for example a ferromagnetic mounting bracket is installed before the power-on of the sensor. Then, the sensor recognizes the ferromagnetic mounting bracket as start condition and can be operated normally with a ferromagnetic tool.
Can a falling ferromagnetic metal part activate qTeach during the operation?
After power-on qTeach is only active for 5 minutes. When operating qTeach during these first 5 minutes an additional time lock of two seconds has to be bridged.
