The Pigtailed 2x2 Assisted Fiber-optic & Electric Rotary Joint allows frictionless rotation of 2 independent optical channels and 24 electrical contacts thanks to motorized assistance.

The rotary joint detects torsion in fiber-optic patch cords connecting it to a moving animal, turning the rotor and allowing the animal to move freely without discomfort.

When a high-stability output is required, the Pigtailed 2x2 Assisted Fiber-optic & Electric Rotary Joint is recommended. These rotary joint have pigtailed, 1 m long FC-connectorized patch cords connected to the optical inputs while the optical output uses two M3 receptacle. The pigtailed patch cords use a 200 or 400 μm core, 0.37 NA or 0.57 NA optical fibers. An ARMO jacket is used to protect the patch cords for maximum reliability.
