Selecting Slip Ring Style

INTERMEDIATE BEARING ASSEMBLY (IBA)

An IBA allows you to terminate the sensors on a separate shaft supported by its own bearings. This allows you to operate the test article with or without the slip ring. It also allows quick removal and re-installation of the slip ring. A key feature of the IBA is the input connector rotating mass is decoupled from the test article. An IBA consists of a rotor on two bearings in a precision housing. The rotor supports a printed circuit board (PCB) where the sensors are terminated. The slip ring is then easily installed using double-ended pins to make the connection between the IBA and slip ring. IBAs also allow flexibility on input configurations.

• Multiple termination capability (for example, 200 termination contacts monitored by a 100-contact slip ring)

• O n-rotor multiplexing switches to monitor a greater number of channels

NOSECONE

A nosecone configuration can be used when space does not allow an IBA. A nosecone is a housing where the input PCB is located and is supported directly by the slip ring rotor bearings. In general, a nosecone configuration reduces speed capability of the system.

TETHERED

A tethered configuration can be used when the mass of the slip ring can be fully supported by the test article rotor. This virtually eliminates supporting static structure and allows large axial movements. In general, a tethered configuration reduces speed capability of the system.

THRU-BORE

A thru-bore design allows the slip ring to fit over a shaft or other centerline object that may have another purpose and cannot be modified. This is typically a custom configuration and very application specific.
