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.

Moog Australia | Precision Motion Control Products
Moog Inc. is a worldwide designer, manufacturer, and integrator of precision motion control products and systems. Moog’s high-performance systems control military and commercial aircraft, satellites and space vehicles, launch vehicles, missiles, industrial machinery, wind energy, marine applications, and medical equipment.
Over fifty years ago, we started as designer and supplier of aircraft and missile components. Today, our motion control technology enhances performance in a variety of markets and applications, from commercial aircraft cockpits, to power-generation turbines, to Formula One racing, to medical infusion systems.
Our history begins with our founder, William C. Moog – inventor, entrepreneur and visionary. In 1951, Bill Moog developed the electro-hydraulic servo valve, a device that translates tiny, electrical impulses into precise and powerful movement. In July of 1951, Bill, his brother Arthur, and Lou Geyer, rented a corner of the abandoned Proner Airport in East Aurora and formed the Moog Valve Company.
The first order for four valves was sold to Bendix Aviation. Larger orders followed from Boeing and Convair. The servovalve revolutionized the aerospace industry and led to the creation of Moog Inc. By 1954, Moog valves were standard equipment on about half of all US fighter planes and more than 70% of all guided missiles.
The introduction of the industrial valve was a success, and by 1960 total sales had grown to more than $10 million. In the aerospace arena, in one of our proudest achievements, our engineers designed and manufactured the actuators on the Saturn C-5 rocket that carried Neil Armstrong to his historic first step on the moon in July 1969.
