Model 292
TWO CHANNEL FIBER OPTIC ROTARY JOINT

The Model 292 is an ultra-compact, two pass, multimode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of optical signals on two separate optical fibers across rotational interfaces.
The Model 292 can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
The FORJ can be assembled with pigtail lengths tailored to the customer’s application. Housing, mounting flange and drive features can also be customized to meet the customer’s requirements. The Model 292 can also be installed with one or both ends having a 90° cable exit, providing even more flexibility when installing the unit into existing slip ring assemblies or installations with little clearance space.
Features and Benefits

- Optional 90 degree cable exits at either end of the FORJ
- Optional fluid-filled version for deep submergence to 10,000 psi (69,000 kPa)
- Can be integrated into existing slip ring designs
- Stainless steel housing
- Long life
- Rugged design
- MIL-STD-167-1 ship vibration
- MIL-STD-810 functional shock (40 g)
