HD Video Slip Rings

An extension of the Orbex miniature capsule slip ring line, our 300 Series HD video slip rings has been enhanced to provide for the transfer of uncompressed, broadcast quality, high definition video through a rotating electrical joint.

Compact, High Performance Video Slip Rings

Orbex 300 HD slip rings utilize industry standard HD-SDI interfaces and have been tested to achieve data rates of 3 GBPS or higher. The HD-SDI interface allows the transfer of 1080p or 1080i uncompressed video on a two-conductor coaxial cable.

High definition video signals are transferred through RF coaxial connectors with 50-ohm specific impedance and MMCX joints. Coaxial cables are included with our HD video slip rings; please specify your preference of RG178, RG316, or RG174 industry standard cables. Custom connectors and alternative coaxial cable options are available, as needed. Contact us to discuss custom slip ring units.

In addition to the HD video channel, 8 or 12 circuits are available for transferring other standard frequency data or power.

Installation Notes: Video Slip Rings

  • Flanged models (M1 and M2) are designed to be mounted with screws and washers. Washers protect against excessive forces. If lock washers are used, flat washers should be mounted between the lock washer and the flange.
  • Non-flanged model (M3) should be mounted by securing the stator; this is best accomplished by inserting the body of the slip ring into a hole that is slightly larger than the O.D. and securing it with set screws, adhesives, or an O-ring.
  • The bearings on 300-HD Series video slip rings are not designed to support external or radial loads. Rotating parts should be supported so as to minimize axial and radial forces applied to the bearings.
