QUIET AS A MOUSEMagShift solenoids have no impact among their moving parts. In power-on mode, noise will measure below 40 dBA, including end-of-travel stop. When the unit reaches end-of-travel position, there is no impact force, which eliminates vibration and minimizes noise. Their construction eliminates residual magnetism that can impede performance and allows the same assembly to be configured as a push or pull solenoid for system flexibility.
