General Purpose Commutator with Through-Bore

The General Purpose Commutator with through-bore features HDMI connections and is built to handle a myriad of your tethered recording needs! It is electronically passive has a 4mm diameter through-hole for passing optical fibers, stimulation lines, or drug delivery tubes. It is well-suited for tethered recordings with our HH128, HH256, Modular, and Neuropixels headstages.

*If you do not need the through-bore for drug delivery or optogenetic stimulation, we recommend the General Purpose commutator which is lighter and has lower torque than the through-bore version.
