Ordering Code:
  • The Pigtailed Assisted Fiber-optic & Electric Rotary Joint is electrically driven as it senses and follows the tethered animal’s rotations. It detects the torsion of the optical cable during animal movement and releases it with a very high sensitivity. The assistance of this rotary joint helps to counter the frictional force of the internal slip-ring and offers quality transmission of electrical signal during any experiment with freely-moving small animals like mice.

    This model is specially designed to work with Doric Snap-in Fluorescence Microscope systems.

    • The holder for the Pigtailed Assisted Fiber-optic & Electric Rotary Joint is included (Holder_ARJ).

    • A compatible FC/FC mating adapter (ADAPTER_FC) is sold separately and can be used to connect different patch cords to the pigtailed patch cord.

    • Note: for Twist-on Fluorescence Microscope systems this model has been replaced by the Assisted 1x1 Pigtailed Fiber-optic & Electric Rotary Joint - 24 contacts.
