Somfy Simu T5 40Nm 12rpm Wired Motor Fit and Torque Guide

Torque sizing decides this reference. A rolling shutter curtain hanging on a 60 mm octagonal tube pulls harder than a fabric screen of the same width, and the load climbs with every slat in the stack. The Somfy Simu T5 40Nm 12rpm (2000652) delivers 40 Nm at 12 rpm from a 120V wired line, which covers heavy aluminum shutter curtains and wide cassette awnings on a 50 mm motor body. Installers reach for it two ways. Some pull a failed T5 operator of the same rating out of an existing box and drop this one in. Others size up from a 30 Nm T5 on a new shutter because the finished curtain came in heavier than the shop drawing promised.

Torque sizing for a 40 Nm Simu T5

Weight and tube diameter set the number you need. A shutter curtain carries its own mass plus the friction of the guide rails, and the motor has to break that load from a dead stop at the bottom limit. Somfy rates this reference at 40 Nm, which sits above the 35 Nm and 30 Nm T5 operators and below the 50 Nm. Installers who guess low find out at the first cold morning, when the rails tighten and the curtain stalls part way up.

Speed matters alongside torque. At 12 rpm the T5 moves a tall curtain at a measured pace that keeps the slat stack from slamming into the header. Faster T5 operators at 18 rpm suit shorter drops and lighter fabric. Pair 40 Nm with 12 rpm and you get the combination Somfy built for heavy exterior work.

Shutters, awnings and screens this motor drives

Somfy clears four applications for the 2000652: awnings, exterior solar screens, interior window coverings, and rolling shutters.

Rolling shutters take the bulk of 40 Nm installs. A shutter box on a 60 mm or 70 mm octagonal tube gives the motor room to seat with an aluminum drive, and the 12 rpm travel keeps a tall curtain moving without the clatter a quicker motor produces on the same drop. Awning work uses the same reference on cassette and semi-cassette frames where the fabric roller carries a heavy front bar. Exterior screens over wide patio openings also land in range. Interior coverings see this torque rating less, since 40 Nm outruns what most roller shade fabric asks for, and Somfy still clears the motor for that duty.

Verified Somfy specifications

The 0 W standby figure earns a note. A wired T5 draws nothing between runs, so a bank of eight shutter motors on a commercial elevation adds no idle load to the panel. The 55 dB rating puts it in the range buyers expect from an exterior shutter operator sitting behind a closed box.

Tube, crown and drive fit

The T5 body measures 50 mm, and the tube has to clear that diameter with the drive wheel seated on the crown. Somfy builds dedicated T5 drive wheels for the tube profiles this family meets in North American boxes. Measure the tube inner diameter before you order, because a drive that sits loose will chew the aluminum wall under 40 Nm.

Octagonal shutter tube at 70 mm takes the Somfy T5/T6 70mm Octagonal Aluminum Drive (9011878), the common choice on European-profile shutter boxes. Smaller round tube on screens and lighter shutters takes the Somfy T5/T6 60mm Round Aluminum Drive (9012950). Wide awning rollers built on Simbac stock call for the Somfy Simu T5/T6 85mm Round Simbac Tube Drive (9420300). Each wheel clips to the motor crown and hands the full 40 Nm to the tube wall. A worn or undersized drive announces itself as backlash at the top limit.

Bracket, head and wiring

The head carries round pins that seat in the Simu T5 bracket range. The Somfy Simu T5 Operator Bracket 80mm x 80mm Square (9520049) bolts to the shutter box wall or the awning frame and accepts the motor head on its pin plate. Check the box depth against the bracket plate before you drill, since the motor needs clearance behind the pins for the cable to exit without a tight bend.

Wiring runs four conductors on the 8.2 ft lead: line, neutral, and one conductor for each travel direction. Each direction gets its own switched hot, and the two must never carry power at the same moment. A shutter rocker switch builds that interlock in. For a scheduled or automated job, feed the motor from a relay card or a building automation output that holds the same interlock.

Limits on this reference are mechanical, set with the adjusters on the motor head. Thirty turns of travel covers a tall shutter curtain on a 60 mm tube. Run the curtain to both ends, then recheck each stop after a week of use, because a slat stack settles and a fabric roll packs down.

This motor answers to wired input alone. It carries no radio receiver, which keeps the install plain: one switch, one motor, no pairing sequence. Somfy covers the remote-control route with the T5Hz, the radio version of the same operator family, so a job that needs handheld or app control has a factory path without an add-on box.

Builders running several shutters off one input should mind the current. At 1.8 A each, a group of motors on a single relay adds up, and the relay rating has to cover the inrush of every motor starting together. Somfy and most controls vendors publish a motor count per output for this reason.

Parts to order with the Simu T5 40Nm

Start with the motor: the Somfy Simu T5 40Nm 12rpm 120V (2000652). Add the drive wheel that matches your tube, then the bracket that matches your box. A 70 mm octagonal shutter tube wants the 9011878 drive and the 9520049 square bracket as the standard pairing. Round tube work swaps in the 9012950 drive, and Simbac awning stock takes the 9420300 wheel. Confirm the connector on the motor you receive against the switch you plan to wire.

Simu T5 40Nm questions

What tube size fits the Simu T5 40Nm?

The motor body measures 50 mm, so any tube you pick has to clear that with the drive wheel seated. Somfy supplies T5 drive wheels for 60 mm round, 70 mm octagonal, and 85 mm Simbac round tube, plus LT50-pattern crowns and drives. Measure the inner diameter of your existing tube and match the wheel to it.

Does the Simu T5 40Nm work with a Somfy remote?

This reference runs on wired control with no built-in receiver, so a handheld remote will not reach it on its own. Somfy builds the T5Hz for radio jobs, with the same torque range and the receiver inside the tube. Pick the Hz version when the opening has no switch leg or the owner wants app control.

How many turns of travel do the limits allow?

Thirty turns, set with the mechanical adjusters on the motor head. That covers a tall rolling shutter curtain on a 60 mm octagonal tube with margin left over. Set both stops with the curtain installed, then recheck them once the slat stack has settled into its final packed height.

Which Simu T5 sits above the 40 Nm model?

The T5 50Nm 12rpm (2000653) takes the next step up at the same 12 rpm travel speed. Move to it when the shutter curtain runs past the 40 Nm margin, on very wide openings or on heavy insulated slat profiles. Below this motor sit the 35 Nm and 30 Nm T5 operators for lighter curtains.
