<p>An electromagnetic pickup includes an insulating body that mounts a coil of wire surrounding a spool portion at one end of the body. A magnetic element is disposed within an axial passage through the body, including its spool portion. A sleeve-like molded plastic cover surrounds the spool portion and other portions of the body, and an encapsulation occupies the spaces within the cover that are not occupied by the body and elements mounted thereto. One end of the magnetic element extends to one end of the body and abuts the inner surface of the wall that encloses one end of the cover. The other end of the body is provided with a self-centering flange that engages the inner surface of the cover, and the other end of the cover is provided with the flange that is embedded in the encapsulation that also forms a seat external of the cover.</p> |
