Common questions
What is the 510S2 4-wire motor?
Part 1038171 is a Somfy LT50 standard 120V motor with a star head. Somfy lists it for exterior solar screens, interior shades and retractable insect screens. It suits projects wired for switch control during construction.
What torque and speed does it deliver?
Somfy's 510S2 10/38 rating gives this motor 10 Nm of torque at 38 rpm. Somfy lists a noise level of 60 dB and an IP 44 rating.
How is it wired and powered?
It runs on 120V/60Hz through a 4-conductor SJTW cable and draws 150 W in operation. Somfy lists 0 W on standby. A wired switch or relay controls the motor, with no radio receiver inside.
Which switches control it?
Use a 120V wired switch, such as the Somfy Maintained Rocker Switch Kit (1800342) or the Maintained Toggle Switch (1800380). Somfy notes wired switches can run one shade or a group.
Can I add remote or app control later?
Yes. The Somfy Universal RTS Receiver (1810627) adds RTS radio control to 110V AC motors like this one. RTS remotes, wall switches and a TaHoma hub can then operate the shade.
Is there a version with a built-in radio?
Yes. The Altus RTS 510S2 (1038165) delivers the same 10 Nm and 38 rpm with an RTS receiver built in, so no control wiring runs to the motor.
