Passive 1x1 Fiber-optic & Electric Rotary Joints - 12 contacts
To facilitate in vivo experiments combining the light stimulation and electrophysiological recordings in optogenetics experiments, we have developed a passive low torque hybrid rotary joint with a number of electrical channels and one optical channel. The FC receptacles on both ends of the rotary joint allow the connection of the input and output fiber-optic patch cords. This product is more compact than the combination of the electrical rotary joint and the 1x1 fiber-optic rotary joint where the optical fiber is passed through the central hole of the electrical joint.
• The holder for the Fiber-optic & Electrical Rotary Joint is included.
• An optional horizontal cable holder keeping cables off-center can be added to increase the effective torque applied on the rotor and help the rotation (HCH). The Fiber-optic & Electrical Rotary Joints come with the pre-installed adapter allowing the fixing on the optional horizontal cable holder.
• An optional gimbal holder can be used to pivot and rotate the rotary joint around an axis (GH_FRJ).
• The output fiber-optic patch cords are sold separately.
• An optional adapter kit can be provided to allow a Harwin-connectorized rotary joint to be used with an Omnetics-connectorized systems (ADAPTER_HO12).
