MPS sorting station D – Combining opto and inductive sensors

 MPS sorting station D – Combining opto and inductive sensors

The MPS sorting station D tackles a number of topics, including combining different types of sensor to detect materials. The station controls a sorting process based on workpiece properties.

The station sorts workpieces onto three material slides. A diffuse sensor detects when a workpiece is placed in the station and triggers transportation of the workpiece to the sorting point: A pneumatic stopper (short-stroke cylinder) stops the workpiece while the conveyor keeps running, and passes it on for sorting onto one of three material slides. Opto and inductive sensors detect the workpiece properties and distinguish between workpieces based on their color and material. A electric deflector sorts the workpiece onto the correct material slide. A retro-reflective sensor monitors the fill levels of the material slides.


  • The highly modular nature of the station makes it incredibly versatile and allows it to be used for many different types of project work.
  • The station can be used individually or together with other stations at various points in a system or process.
  • With the aid of this station, students will acquire specialist skills in the fields of materials detection, combining sensors, and programming sorting functions.
