MR dampers are similar in construction to fluid viscous dampers and utilize MR fluids instead of hydraulic oil. They are widely used in machines, automobiles, and civil engineering applications due to their low power consumption, quick response, easy control, and adjustable damping force. In an MR damper, the piston includes coils capable of delivering a magnetic field in the piston’s flow channels. The MR fluid changes its viscosity, from a liquid to a semi-solid, when subjected to a magnetic field. In these terms, the piston acts as a “magnetorheological valve”, and the damping is the result of the friction between the fluid and the flow channel. By controlling the characteristics of the magnetic field, the damping behavior is easily adjustable without the need to change the mechanical setup of the system.

All our InShock systems are powered by 12V and are controlled by an internal magnetic sensor system.
