CT1 plug pair (CAc30 extension); same light-side plug family as on our system cables with CT1B.
We verify connector compatibility ourselves (as of 2026-07-30). The statement describes the mechanical and electrical plug interface. It is not a warranty of further properties. Before installation, check the technical requirements of the drive system and the lighting. If unsure: use a specialist workshop.
The same CT1B system cables as for Litemove/Supernova: Bosch 1300 mm, Shimano 1300/1900/2300 mm, Yamaha 1300 mm, Avinox CT1B 400 mm, plus CT1 extension 300 mm. Open-end variants without CT1B are for other connection types. They do not automatically replace the HIGO plug connection.
