The Doric
Electric Rotary Joint
is used to transmit electrical signal from a moving sample to a fixed recording system. It
consists of high precision ball bearings and of a slip ring to transmit signal. It is composed of a
Stator
, which stays immo-
bile, and a
Rotor
that moves (Fig.
). The electrical signal is transmitted through 2 possible types of connectors: Male
Harwin (6 or 12 contacts) or Female HDMI (
Blackrock micro
compatible pinout available). This is a device intended for
fundamental research, for use with rats and larger animals. The central clearance hole is used in cases where electrical
and optical signal is required. It allows for passage of one or two optical fibers with M3 or ferrule/sleeve connectors.
