Magnetic Gripper for Cobots

You are here

Safe, Reliable, Smart and Energy Efficient Gripping Tool

After some a period of trials and validation in the last few years, collaborative robots are now starting the be rolled-out in the industry. Alongside, a complete new range of dedicated product is appearing. Those new tools are properly designed in term of power and function for cobots applications. 

 


Among those new tools, once can find magnet grippers. They consist in a pneumatically or electrically actuated mobile magnet placed above a fixed one in order to activate an outer magnetic field that allows handling of ferrous parts while being extremely compact. Magnetic power is already installed in the product so the need for energy is minimal. And, unlike common preconception, residual magnetism of handled parts stays low.

Last important point for cobots but also industrial robots: safety. Our magnet gripper is intrinsically safe by design, once actuated it does not need any source of energy to keep its ON position. Parts transfer with this gripper can then occurs without energy, actuation can be performed at a fixed station at the start and arrival of the process.

This technology is quite empirical, tool dimensioning then needs experience-based expertise which PES can offer. Do not hesitate to contact us for your next project. The offered power range is quite large and those units can equip the smallest collaborative robot as well as the larget industrial one.
