Pin-style brackets accept a motor head carrying two pins, and Somfy builds the Roll Up Wired R28 Pin Mount (1002832) for exactly that bracket. Installers who reach for this reference already have the brackets on the window and a small tube on the bench. The motor turns 0.8 Nm at 30 rpm on 24V DC. That output moves roller shades, zebra shades, Roman shades and solar screens in bedrooms, offices, conference rooms and hotel guest rooms.
Match the head to the bracket you already own
Somfy splits the Roll Up Wired R28 into three head styles so the motor drops into the bracket a fabricator has already specified. The pin mount seats in pin-style brackets. The ear mount and the starhole mount take their own bracket families. Buyers who order the wrong head end up shimming a motor that was never meant to sit in that cradle, and the shade hangs crooked from day one.
Check the bracket before you check the torque. Two short pins projecting from the motor head mean you want 1002832. Fabricators building on RollEase SkyLine or ZMC XL hardware should confirm the bracket plate they use, since those systems carry their own adapter plates.
Shades this motor suits
Somfy publishes the R28 for roller blinds, solar screens, zebra blinds and Roman blinds. The 0.8 Nm output puts a ceiling on the fabric weight and the roll diameter, so this reference belongs on small and medium openings. A bedroom roller at 36 inches wide sits inside the band the R28 was built for, and so does a 42 inch zebra shade over a kitchen sink.
Larger openings move up the line. Somfy's 40 mm and 50 mm families carry more torque for wide commercial screens and heavy blackout fabric. Specifiers running a mixed job keep the R28 on the small windows and step up where the fabric weight climbs.
Removing the lift cord matters in two settings. Child-occupied rooms lose a strangulation hazard. Commercial projects clear a corded-product question that shows up in specifications and in insurance reviews.

The IP 30 rating keeps this motor indoors. Somfy rates it for interior window coverings, so an exterior screen or an awning calls for a sealed motor from another family.
Tube, crown and drive
Tube inside diameter decides whether the motor seats at all. Somfy publishes 1.05 in as the minimum inside diameter for the R28 body. Anything tighter leaves the motor sitting proud of the tube end and the drive never engages the wall.
The crown locates the motor inside the tube. The drive transfers the torque to the tube wall. Order both as a matched pair for the tube you cut, never one alone. Shade Motors Direct stocks the Somfy Crown for RollEase and ZMC XL Series 1.25 inch tube (9018474) with its matching Somfy Drive for the same 1.25 inch tube (9018476). Fabricators rolling Hunter Douglas Silhouette fabric take the R28 Sonesse Crown and Drive Kit for Silhouette (9025816), which pairs the two pieces in one part number.
Somfy also publishes crowns and drives for 26.1 mm tube and for the 1.5 inch RollEase and ZMC XL series, so an unusual tube on an existing shade still has a path. Measure the inside diameter with calipers at the cut end. A tape measure across the outside tells you nothing about the wall thickness.
Wiring, power and control
Somfy Wired Technology runs this motor on 24V DC, which keeps the install inside low-voltage rules in most jurisdictions. A shade fabricator or a low-voltage technician can pull the cable without an electrician on site. Buyers supply the transformer separately and size it from the 7.7 W operating draw, with headroom for every motor on the circuit plus the 0.407 W each one holds in standby.
Plan the cable run before the shade goes up. Pull the low-voltage cable to the head rail during rough-in, leave service length at the motor end, and label both ends. Retrofits with no wall cavity to chase usually route the cable through a fascia or a surface raceway. Confirm the connector on the motor you receive against the lead on your power supply before you cut anything.
Electronic limits set the open and closed stops, and the 60 turn capacity covers the roll count a small shade needs. Set the limits after the fabric hangs on the tube, since the roll diameter changes where the bottom bar lands.
Somfy wired controls drive this motor from a wall station, which suits a single window or a small room. Projects that need groups, presets and timed scenes move the motor onto a controller built for multiple outputs. Somfy's IGC 4-in-1 controller gives four shades individual and group commands from one device, and integrators wire the R28 into it the same way they wire the rest of the Somfy Wired Technology line.
Dealers running a larger job can bring these shades under a Somfy control platform alongside RTS and Zigbee motors on the same site. Somfy keeps the control layer consistent across its families, so a conference room with wired R28 motors on the interior shades and radio motors elsewhere still answers one set of scenes.
Order the motor and the parts around it
Two measurements finish this order. Confirm the bracket takes a pin-mount head, then check the tube inside diameter against the 1.05 in minimum. Add the crown and drive that match your tube profile, plus a 24V transformer sized for your motor count.
The Somfy Roll Up Wired R28 Pin Mount (1002832) ships as the motor on its own, so build the kit around it in one order and keep the job moving. Fabricators who stock the 1.25 inch crown and drive alongside the motor cover most of the tubes that cross the bench.
Questions installers ask
What tube does the Roll Up Wired R28 fit?
Somfy publishes a minimum tube inside diameter of 1.05 in for the R28 body. Crowns and drives exist for 26.1 mm tube and for RollEase and ZMC XL series tubes in 1.25 inch and 1.5 inch profiles. Measure the inside diameter at the cut end with calipers, then order the crown and drive that match that profile.
Does this motor need an electrician?
Somfy Wired Technology runs the R28 on 24V DC from a separate transformer, which keeps the motor wiring in the low-voltage category in most jurisdictions. A shade fabricator or low-voltage technician handles the run. Check your local code, since the line-voltage side of the transformer still falls under electrical rules.
Which crown and drive do I order for a 1.25 inch tube?
Pair the Somfy Crown for RollEase and ZMC XL Series 1.25 inch tube (9018474) with the matching Drive (9018476). Order both pieces. The crown centers the motor in the tube and the drive carries the torque into the tube wall, and one without the other leaves the assembly unable to turn the shade.
How much weight will 0.8 Nm lift?
Torque at 0.8 Nm and 30 rpm places this motor on small and medium shades, and the usable width depends on fabric weight, roll diameter and tube stiffness together. Somfy lists roller blinds, solar screens, zebra blinds and Roman blinds for the R28. Heavier blackout fabric on a wide commercial opening belongs on a 40 mm or 50 mm Somfy motor.
