The 15' Sensor Cable from TriggerSmart is the standard cable that connects the sensors to the UK1 TriggerSmart Controller. This cable is included as part of the TriggerSmart Kit but can be purchased separately as a spare or to be used with additional sensors when using the TriggerSmart system. Along with a separately purchased connector it can also be used as an extension sensor cable. The 9' (4.6m) cable has 3.5mm jacks on both ends.
