Electromagnetic actuator for a fuel injector; the electromagnetic actuator is provided with an electromagnet, which has a fixed magnetic core which is delimited at the base by a first annular contact surface, and with an anchor, which is mechanically integral with a shutter, it can be displaced against the action of a spring towards the magnetic core by the effect of the force of magnetic attraction produced by the electromagnet, and is delimited at the top by a second annular contact surface, which is parallel to, and faces the first contact surface; between the two contact surfaces there is interposed an annular separation body, which is substantially flat, is made of non-magnetic material, and is integral with the magnetic core or with the anchor.
