Somfy Tilt 50 WireFree Through-Shaft RTS Blind Motor Guide

The part that decides this motor is the tilt rod already inside the headrail. The Somfy Tilt 50 WireFree Through-Shaft RTS Motor (1240276) slides onto that existing rod and turns the slats of a 2 inch horizontal blind without cutting or replacing anything. It runs on a 12V battery, so a finished blind becomes motorized with no wiring and no fabrication of a new shaft. For a fabricator adding motorized tilt to a wood blind line, the through-shaft design is what keeps the retrofit fast.

Blinds the Tilt 50 WireFree suits

The Tilt 50 motorizes the tilt function of 2 inch horizontal blinds in wood, faux wood, composite, and metal. It moves the slats between open and closed and holds any angle in between, so a room dims by degrees instead of jumping to full shut. This motor tilts the slats. It does not raise or lower the blind, which stays on its lift cord or lift mechanism. That split matters when you spec a job, because a client who wants both tilt and lift needs a separate plan for the lift function.

Wood and faux wood blinds carry heavier slats than aluminum, and the Tilt 50 turns all four slat materials on a 2 inch blind. The motor improves on the sound performance of the previous generation, which helps in a bedroom or a home office where the blind sits close to a desk.

Shaft adaptors and headrail fit

The through-shaft passes through the motor and couples to the blind's tilt rod, and the coupling depends on the rod's shape and size. A wand-style rod, a hex rod, and a square rod each need the matching adaptor. The Somfy Tilt 50 5.5mm Hexagonal Through-Shaft Adaptor (9025929) couples the motor to a 5.5 mm hex tilt rod, and Somfy offers a family of adaptors in 4 mm, 5 mm, 6 mm, and 6.4 mm hexagonal, square, and D-shape profiles for other headrails. Measure the rod across the flats and identify its profile before you order, since the adaptor is the one part that makes or breaks the fit.

Verified specifications

These figures come from Somfy's published data for part 1240276. The 56 dB noise level and the IP20 index are worth logging, since the IP20 rating marks this as an interior motor for a headrail, not an exterior part.

Battery and power options

The Tilt 50 takes 12V from an external battery, and Somfy gives you a few ways to feed it. The Somfy Reloadable 12V DC Battery Wand (9018685) hides a set of cells in a slim wand that mounts beside the headrail, which suits a clean residential look. For a rechargeable option, the Somfy Rechargeable Lithium-ion Battery Pack (9021217) lifts off to charge and drops back without tools. Somfy also offers a solar panel kit and a plug-in 12V supply for the motor, so a single blind, a bank of blinds, and a hard-to-reach window each get a power source that fits. Size the battery to how often the slats move, because a blind that tilts twice a day sips far less than one on an hourly sun schedule.

Install notes for a fast retrofit

The through-shaft design earns its keep on a retrofit. The motor slides onto the existing tilt rod, so a fabricator skips cutting a new shaft and skips re-drilling the headrail. Set the motor position on the rod so the shaft engages fully and the headrail end cap still seats. The integrated cable and the built-in programming button keep the bench work short: mount the motor, couple the adaptor, set the two limits, and pair the remote. Confirm the slats close in the direction the client expects before you leave, since reversing the tilt direction is a quick step at setup and a callback later. A headrail adaptor holds the motor square in the rail on blinds where the tilt rod sits off center.

Control and slat positioning

The Tilt 50 carries an RTS receiver, so it pairs with Somfy RTS remotes and wall switches. For precise slat angles, the Somfy Situo 5 Channel RTS Pure Remote (1870575) drives incremental tilt across five channels, so one remote sets the angle on five blinds or five groups. Add a Somfy smart hub and the same blind joins app control, schedules, scenes, and voice, which lets a whole room of blinds track the sun through the day. The built-in programming button and the integrated cable keep setup short on the bench or at the window.

The Somfy Tilt 50 WireFree Through-Shaft RTS Motor (1240276) is the battery tilt motor for 2 inch wood and faux wood blinds, and the right shaft adaptor makes it a drop-in retrofit.

Frequently asked questions

Does the Tilt 50 raise the blind or only tilt it?

The Tilt 50 WireFree tilts the slats only. It opens, closes, and holds any slat angle on a 2 inch horizontal blind, but it does not raise or lower the blind. The lift function stays on the blind's existing cord or lift system, so a full motorized blind needs a separate plan for lift.

Which tilt rod does the through-shaft fit?

The through-shaft couples to the blind's existing tilt rod through a matching adaptor. Somfy offers 4 mm, 5 mm, 5.5 mm, 6 mm, and 6.4 mm adaptors in hexagonal, square, and D-shape profiles. Measure the rod across the flats and identify the profile, then order the adaptor that matches, since that part sets the fit.

What powers the Tilt 50 WireFree?

The motor runs on 12V from an external battery. Somfy offers a reloadable battery wand, a rechargeable lithium-ion pack, a solar panel kit, and a plug-in 12V supply. Choose the source by how often the slats move: a twice-a-day tilt draws far less than an hourly sun schedule, so runtime scales with use.

How do you set precise slat angles?

Pair the Tilt 50 with a Somfy RTS control such as the Situo 5 Channel remote, which drives incremental tilt across five channels. The motor also offers soft start and stop and adjustable speed for smooth slat movement. Add a Somfy smart hub for app control, schedules, scenes, and voice, so a room of blinds tracks the sun.
