The Two-Optical-Two-Electrical Slip Ring, Industrial-Grade Rotary Joint is an industrial-grade rotary joint: it passes 2 optical channels + 2 electrical circuits across a rotating interface, so a winch drum, turbine or sensor mount can turn continuously without twisting the cable. Sealed bearings and a corrosion-protected housing make it suitable for marine decks and rotating equipment in salt air.

Product Highlights
- Precision rotary transfer: 2 optical channels + 2 electrical circuits across a continuously rotating interface.
- Sealed for marine duty: sealed bearings and corrosion-protected housing for deck and salt-air service.
- Compact industrial build: drops into winch drums, cable reels and rotating sensor mounts.
- Low insertion loss: precision contact geometry keeps signal quality stable over the full rotation.
- Long service life: gold-alloy contacts and maintenance-friendly bearing arrangement.
- OEM/ODM: circuit count, optical/electrical mix and mounting flange built to your drawing.

Structure & Durability
Optical and electrical channels run through concentric paths in the rotor; precision-machined slip surfaces and gold-alloy brush contacts carry the electrical circuits while aligned fiber optical couples pass the optical channels. Bearings at both ends hold rotor alignment, and the sealed housing keeps salt dust and spray out of the contact zone.
