Full range drive unit

A moving element and an answer identical to the 215-2000 alnico.

Its advantage is the possibility of adjustment of these parameters thanks to a powerful electromagnetic engine. Adaptable of this fact to many enclosures, it requires an external power supply (ideal of 10 to 14V for 5A).
