High duty cycle, accuracy and power achieved with a switchable magnet

Magnets for bin picking

Nowadays, automotive components suppliers need to increase productivity while mitigating production costs.

The production means have to be more reliable, more available, more versatile and cheaper to fulfill the industrial goals.

When it comes to alternators components that can be grabbed by a magnet, the technical challenge is to find a tool that offers compactness for easy access inside narrow spaces and power to handle those heavy winding parts. Moreover, the tools shall withstand high duty cycle to follow production flow. 

The switchable magnet AR series offered by PES perfectly meets the above-mentioned expectations. They combine power and compactness for full structured bin picking capabilities.

Indeed, the robot shall slip into the parts to touch the magnet working surface that are hard to access but EOAT size is also critical for access in bin corners at different depths.


Key Features

  • High power/contact ratio
  • High duty cycle to support production flow needs
  • Pneumatically actuated, no need for energy during the handling operation
