Assisted Electrical Rotary Joints - 24 contacts

  • Unit price per 

Ordering Code:
  • The Assisted Electrical Rotary Joint is a rotary joint that transmits electrical signal over 24 contacts. Compared to our passive Electrical Rotary Joint, the motor Assisted Electrical Rotary Joint is effectively frictionless, thus allowing its use with mice. The rotary joint is primarily used in electrophysiology with small animal subjects.


    • The number of electrical contacts does not necessarily equal the number of recording channels.

    • The torque sensor included with the Assisted Electrical Rotary Joints is also used as a cable holder with its rod and its clamp. The adapter to secure the rotary joint on the sensor is preinstalled.
