Speed sensor encoder wheel and method of making |
摘要 |
A method of making an encoder for use in a speed sensor includes providing a metal tube. A material containing ferrite is then extruded over the metal tube to produce an encoder tube. The encoder tube is cut to a given length to form an encoder. The encoder is then magnetized within a magnetic field.
