What torque and speed does the Sonesse 40 WT 409R2 deliver?
Somfy rates part 1240379 at 9 Nm of torque and 14 rpm on 120V AC. It draws 0.95 A, and Somfy lists a noise level of 40 dB.
What is the smallest roller tube this motor fits?

What does the Fast Connector do?
The motor ends in a 1.64 ft 4-wire lead with a Somfy Fast Connector. Your supply cable plugs into it at the motor, so there is no splicing inside the headrail.
How do I wire and control it?
It is a standard 4-wire 120V AC motor, run from a wired wall switch or a third-party relay. Somfy rates it IP 44, with an operating range of 32 °F to 140 °F.
How are the limits set?
The motor uses mechanical limit switches with a capacity of 40 turns. You set the upper and lower stops at the motor head during installation, before the shade goes into service.
Is there a version with a built-in radio?
Yes. The Somfy Sonesse 40 RTS 409R2 (1240382) keeps the 9 Nm and 14 rpm and adds an RTS receiver for Somfy remotes and wall switches. For a Zigbee network, choose the Sonesse 40 409R2 Zigbee 3.0 motor (1245922).
