What Is The Difference Between An Electrical Straight Coupler And An I-Coupler in a OneTrack System?
What Are They Used For?
The Electrical Straight Coupler and the I-Coupler are both used to splice two pieces of OneTrack in line.
Electrical Straight Coupler I-Coupler
Differences
Electrical Straight Coupler - Requires 4 in (10.16 cm) pendant clip to stabilize joint for structural integrity. Does not have any power or data feed capabilities, but creates data and power continuity between two pieces of track without adding any additional length. It does not require a coupler housing when using OneTrack Backbone.
I-Coupler - Includes two separate wire entry points where power and data may be fed (top feed only) to the track. It may also be used to feed two separate sources of power or two separate sources of data into the two different OneTrack pieces being spliced by the I-Coupler. It will add 4" of length to the track and requires a corresponding coupler housing when used with OneTrack Backbone.
