1. A slip ring assembly, comprising:
- first and second halves of a slip ring having a contact surface for rotational engagement with a stationary brush element for transferring electrical signals there between, the contact surface having a smooth surface at the junction of the first and second halves;
a fastener locating the first and second halves to form a ring shape; and
an electrical contact on the ring for carrying electrical signals.

Abstract
A split slip ring assembly formed from first and second halves of a slip ring having a contact surface for rotational engagement with a stationary brush element for transferring electrical signals there between. The contact surface has a smooth surface at the junction of the first and second halves. A fastener locates the first and second halves to form a ring shape. An electrical contact on the ring carries electrical signals between the slip ring and the brush element. An alignment element aligns the first and second halves to form the smooth surface at their junction.
