Another new motor in our range is the Sonesse 40 Wire Free RTS battery motor – a new motor from the Somfy range with 3 Nm power and a 4600 mAh battery. A motor designed for medium-sized roller blinds in the Medium or Medium Plus system and used for tubes with a diameter of ø 44 mm and ø 52 mm. The Sonesse 40 Wire Free RTS can also be used for 50 mm venetian blinds. Ideally suited as a drive for aluminium blinds, for wooden blinds (where the slats’ package is much heavier), it can be used for small and medium-sized venetian blinds due to its limited power of 3 Nm)
