Single-Channel Fiber Optic Rotary Joints

SPINNER Single-Channel FORJ 1.14

The FORJ 1.14 (with an outer housing diameter of 14 mm), a member of SPINNER’s family of single-channel fiber-optic rotary joints (FORJ), features maximum performance in a minimum of space. It comes in two different versions, both classified with IP54 ingress protection.

Standard version 1.14

The standard 1.14 is a workhorse characterized by its small form factor and robust design, making it an excellent choice for a wide range of industrial applications.

For even greater flexibility, the FORJ can be used in combination with BiDi media converters for easy integration into existing Ethernet networks. SPINNER has dubbed these combinations “rotary data interfaces” (RoDi). The standard 1.14 version handles rotational speeds up to 3,000 rpm and can be equipped with our proprietary FLEXIFLANGES.

Premium version 1.14P

The premium 1.14P model, an enhancement of the standard FORJ 1.14, achieves rotational speeds of up to 20,000 rpm with the same dimensions and very low typical insertion losses of less than 1.0 dB. It was primarily designed for medical and sensor applications that require high rotational speeds (e.g. for intravascular optical coherence tomography) and the ability to transmit low-level signals.

SPINNER Single-Channel FORJ 1.14L (Right-Angle)

Based on the 1.14 the 1.14L-type, features a fiber optic output at a 90° angle to the axis of rotation. Reliable optical components and high-precision production ensure exceptional reliability and a long service life. These solutions are ideal in installation situations with extremely limited space, such as cameras, LIDAR systems, civil and military optronic sights, and targeting systems.

SPINNER is the only rotary joint manufacturer offering FORJs for both single and multiple channels with right-angle outputs.

SPINNER Single-Channel FORJ 1.17

SPINNER has developed the single-channel fiber-optical rotary joint FORJ 1.17PC with pressure compensation for subsea applications down to 10,000 m below the surface.

Based on experience gained with the pressure-compensated 1.17PC, the 1.17 was adopted for the “above water” world, making it ideal for use in wet or dirty environments. Moreover, because it integrated the optimized optical system of the 1.14 there are no trade-offs in terms of optical performance. The 1.17 is made of saltwater-resistant tempered steel and delivers IP68 ingress protection thanks to an integrated rotary surface seal. Besides featuring exceptional shock and vibration resistance, it is impervious to moisture in seawater environments.

The 1.17 with an outer housing diameter of 17 mm is ideally suited for use where it is exposed to the weather or in machines containing lubricant, and is therefore a popular choice for wind turbines, ships, and offshore applications.

SPINNER Single-Channel FORJ 1.068

The SPINNER single-channel FORJ 1.068 – our smallest fiber optic rotary joint – boasts a diameter of only 6.8 mm, making it ideally suited for use in extremely tight conditions.

The FORJ 1.068 integrates the same optical system as the FORJ 1.14. Because it’s filled with air instead of oil, it has an especially long service life and resists degradation. An attached flange facilitates handling and attachment. It can also be retrofitted in existing systems as a FFF (form fit function) replacement.
