TBI-ETH / Data integrity

Ethernet, EtherCAT & USB Slip Rings

Specify shielded rotating data paths for GigE Vision, industrial Ethernet and USB alongside the power circuits your rotating assembly needs.

Typical design brief: Machine vision stations, robotic end effectors and camera systems.

IMPERIAL / METRIC SELECTION ENVELOPE

Define the bore and every circuit.

These are design request ranges, not an orderable stock specification. Exact dimensions, current derating and maximum speed require a released drawing.

Exact imperial conversions: 0.5″ = 12.7 mm · 1″ = 25.4 mm · 1.5″ = 38.1 mm · 2″ = 50.8 mm · 3″ = 76.2 mm · 4″ = 101.6 mm. Metric 50 / 70 / 100 mm bores remain separate choices.

APPLICATION REVIEW

What determines a workable TBI-ETH?

A connector label does not prove channel performance. Protocol, cable length, pair geometry, shielding and rotating error tests must be agreed together.

Protocol and required data rate; device and host
Rotor / stator cable lengths and connector pinout
Packet error or bit-error acceptance at operating speed

Replacing an existing assembly? →

Concept mounting: rotor on independently supported shaft, stator tab restrained with compliance

Give the stator a flexible stop.

For a shaft-mounted design, secure the rotor as its drawing specifies and restrain the stator with an anti-rotation tab that accommodates misalignment. Avoid rigidly locking both sides. Mounting is model-specific; flange and capsule designs may differ.

Assembly options

Illustrative accessory allowances, subject to compatibility and written quotation. Two options are preselected; clear either if unnecessary. Connector quantity, circuit count, wire gauge, custom harness work, sealing, shipping and any NRE are priced for the agreed configuration.

Connector preferenceExtended lead length

Connector and extended-length selections apply only when their corresponding assembly option is checked. Wire material, sealing scope and connector suitability require approval.

No payment is collected. No stock, dispatch date or performance is reserved by this request.

TBI-ETH engineering questions

Does one Ethernet design support every industrial bus?

No. Define EtherCAT, PROFINET or the exact protocol and link speed. Validate with the intended devices and cable assembly.

Can USB 3.0, HDMI or DisplayPort use ordinary signal rings?

These interfaces need a dedicated impedance-controlled path and system validation. Availability is reviewed for the requested configuration.

Compare adjacent slip ring architectures.
