Common questions
What torque and speed does the Sonesse 40 406A2 WT deliver?
Somfy rates part 1240378 at 6 Nm of torque and 24 rpm, with a 44 dB noise level and 15.44 lb of traction force. It is a wired 120V motor for interior shades, blinds and projection screens.
What is the smallest roller tube it fits?
Somfy lists a minimum tube inside diameter of 1.46 in. Our store pairs it with the 40mm Octagonal Tube (1781154) and the LS40 Crown and Drive Set (9012224), along with the rubberized LS40 sets (9016654, 9016655).
How is the motor powered and wired?
It runs on 120V AC at 60 Hz, with a 0.95 A rated current and a 120 W draw while running. A 1.64 ft, 4-wire pigtail ends in a Fast Connector, and a 4-wire Fast Connector extension such as the 8.4 ft cable (9021118) reaches your wiring.
What head type does it use?
Somfy lists a round head for this RH model. Confirm that your bracket or motor plate accepts a round Sonesse 40 head before you order, since the right mounting part depends on your shade hardware.
How are the up and down limits set?
Somfy lists a mechanical limit switch with a capacity of 40 turns, which caps how many tube turns fit between the upper and lower stops. The installer sets both stops on the motor during setup.
Which controls work with it, and is there a smart version?
It takes wired control from a switch or relay and has no radio receiver. For app and smart-home control on the same platform, the Sonesse 40 406A2 Zigbee 3.0 motor (1245921) delivers 6 Nm at 24 rpm.
