A Twist Capsule is a device that enables power and data transfer using a limited rotation mechanical joint. The basic concept is a flexible circuit that is allowed to wrap and unwrap as rotation happens.

Typical uses are Solar Array Drive Mechanisms for space applications and a variety of sensors/gimbals that require only limited rotation. The amount of rotation can vary, based on customer requirements. Many designs have more than 360 degrees of rotation. Using a Twist Capsule also provides mechanical contact for all data and power lines, meaning there is no sliding contact surface as one would see in Slip Rings.

EVERAXIS has a wide variety of Twist Capsule designs to choose from as a baseline, which will reduce design and development time. Furthermore, most of the designs are suitable for harsh environments.
