The BS-TL T-Cable is a cable with pre-installed connectors for the MiBoxer stair lighting system. 1 piece = 1 connector – for connecting 1 step. Each connector is 250mm long, with 400mm spacing between connectors. To connect motion sensors Sensor A and Sensor B, it is recommended to order 2 extra connectors, meaning 2 extra pieces more than the number of steps.
