Torque-free Commutator - SPI
Torque-free Commutator - SPI
SKU: OEPS-7761
The Torque-free SPI Commutator enables tangle-free connection between a stationary data acquisition device and the headstage of a freely-moving animal. It is compatible with any 3D-capable SPI headstage for the Acquisition Board (3rd Generation). Torque-free active commutation is driven by interfacing with a variety of head-orientation tracking technologies including:
Recording devices that contain on-board Inertial Measurement Units (IMUs):
OR Computer vision:
Works in the Open Ephys GUI (v1.0 and above) for acquisition with the Acquisition Board (3rd Generation).
Package includes:
1 Torque-free SPI Commutator
This device requires additional components to operate. Please check the device connectivity list to purchase any cables, tethers and power supplies you might need.

The purpose of Open Ephys Commutators is to promote natural animal behavior by nearly eliminating mechanical stress during neurophysiology experiments. This is achieved by minimizing torque exerted on the animal during optical or electrophysiological recordings by rotating the tether in lock step with the animal’s real-time orientation.
