The Simu T5Hz 30Nm 12rpm 120V carries Somfy reference 2005136. It is a 50 mm class tubular motor with a Simu Hz radio receiver built into the head, so a dealer wires power to it and nothing else. Somfy rates it at 30 Nm of torque and 12 rpm on 120V/60Hz power. Two numbers settle most orders for this motor: the torque it produces and the tube it will slide into.
Tube diameter decides the fit
Measure the tube first. The 2005136 needs a tube with an inside diameter of 1.85 in or more. The motor body runs 1.77 in across and the head widens to 1.97 in, so a 2 in round tube or a 70 mm octagonal shutter tube takes it without a fight. Anything tighter will not seat, and no adapter solves a tube that small.
Dealers who roll narrow interior shades move down to a 40 mm class motor for that work and keep the T5 class on exterior openings. Torque sets the second half of the decision. A 30 Nm motor at 12 rpm handles a mid-size folding arm awning, a tall exterior solar screen, and a rolling shutter curtain in the weight range where a 20 Nm head runs short of margin. Somfy lists the T5Hz range for awnings, exterior solar screens, interior window coverings and rolling shutters.
The work a 30 Nm T5Hz takes on
Speed matters on heavy fabric. At 12 rpm this motor travels slower than the 18 rpm versions in the same family, and that steadier pace suits a thick shutter curtain or a wide screen with a loaded bottom bar. The tube turns twelve times a minute, so an installer can watch a long drop land on its stop instead of chasing it.
Electronic limits give the motor a 36-turn travel capacity. A fabricator working out drop length multiplies the turns by the rolled circumference of the tube and fabric, then checks the result against the finished height. Shutter builders use the same arithmetic on slat packs. The 36 turns cover most residential and light commercial drops on a 2 in to 85 mm tube.

Crowns, drives and brackets for a T5 head

The round head with pins drops into a Simu T5 operator bracket. Somfy publishes bracket patterns at 80 x 80 mm, 100 x 100 mm, 48 mm and a pin mount, and the T5 operator bracket 80 x 80 mm covers the common square shutter box and awning cassette. Bolt the bracket to solid structure. A shutter box face that flexes will transfer that movement into the tube.
Pick the drive to match the tube profile. The T5/T6 70 mm octagonal aluminum drive suits a standard 70 mm octagonal shutter tube. For a 60 mm octagonal tube, the 60 mm octagonal LT50/60 aluminum drive with stop brings the stop collar with it. Somfy also lists LT50 crowns and drives from 2 in up to DS 85 mm against the T5 range, so an awning builder can hold one motor platform across several tube sizes. Add a drive stop and screw where the drive needs to lock in place inside the tube.
Match the crown to the drive. A 70 mm drive on a 60 mm tube will not grip, and a drive that spins inside the tube chews the inner wall on the first few cycles.
Radio control on 433.420 MHz
The receiver sits inside the motor head, which removes the receiver box from the install and the wiring that goes with it. Somfy publishes an open field range of 492 ft on 433.420 MHz. Metal shutter boxes, foil backed insulation and masonry cut into that figure, so a dealer plans a transmitter position with line of sight to the window where the install allows it.
Simu Hz transmitters pair to this motor and set its limits. Simu states that Somfy RTS controls work with the Simu Hz motor range. An installer running a mixed site confirms the protocol on each handset before pairing, since a single site often holds both generations of remote. Standby draw sits at 0.38 W, which keeps a bank of motors reasonable on a shared circuit.
Install notes before the motor goes in the tube
Class I insulation means this motor needs a ground connection. Land the ground on the 3-wire white lead and test it before the tube goes up, because a motor already inside a shutter box turns a two minute check into an hour. Rated current sits at 1.5 A and running power at 170 W, numbers a contractor needs when sizing a circuit for several motors in one row of openings.
IP 44 covers splashing water from any direction, which suits a shutter box, an awning cassette and a covered exterior screen pocket. The operating range runs from -4°F to 140°F. Somfy backs the motor with a 5 year warranty.
Set the limits with the fabric or slat pack already attached. The weight changes where the roll lands, and limits set on a bare tube drift once the shade hangs on it.
The Simu T5Hz 30Nm 12rpm 120V (2005136) ships from Shade Motors Direct as a genuine Somfy part with the 5 year warranty behind it. Order the bracket and the drive with the motor. A T5 arriving on site without its crown and drive leaves a crew standing around a tube they cannot close up.
Frequently asked questions
What tube does the Simu T5Hz 30 Nm fit?
The motor needs a tube with a minimum inside diameter of 1.85 in. The body measures 1.77 in and the head 1.97 in. A 2 in round tube or a 70 mm octagonal shutter tube accepts it with the matching crown and drive. Smaller tubes call for a 40 mm class Somfy motor instead.
Does the T5Hz 2005136 need a separate radio receiver?
No. Somfy builds the Simu Hz receiver into the motor head on 433.420 MHz, so the install needs power only. A dealer pairs a Simu Hz transmitter to the motor and sets the electronic limits from that handset. Open field range reaches 492 ft.
How much travel do the limits allow?
Somfy gives this motor electronic limits with a 36-turn capacity. Multiply the turns by the rolled circumference of tube plus fabric to check a drop. That figure covers residential and light commercial heights on tube sizes from 2 in to 85 mm.
Which applications does Somfy list for this motor?
Somfy lists the T5Hz for awnings, exterior solar screens, interior window coverings and rolling shutters. At 30 Nm and 12 rpm the 2005136 lands in the middle of that range, suited to a mid-size awning or a tall screen where a 20 Nm motor would run close to its limit.
