Somfy J410 HTM external blind/block motor used & refurbished | louvre

Somfy J4 HTM / WT / RTS / io – external blind & blind motor (used & refurbished | tested)
“I am the motor that directs every light – precisely, quietly and weatherproof, so that your blinds always move perfectly.”
I offer you used Somfy J4 external venetian blind motors - the professional drive solution for external venetian blinds and facade systems.
The J4 series from Somfy stands for precision, smooth running and durability - developed to precisely control slat movements, react to wind and sun and work reliably even in unfavorable weather conditions.
The motors are available in different control versions:
 
 
 
J4 HTM: classic, mechanical drive for simple switching controls – ideal for standard systems.
 
 
J4 WT: Wired version for group or central controls with automatic functions.
 
 
J4 RTS: Radio motor with proven Radio Technology Somfy – wireless, low-interference, ideal for retrofit solutions.
 
 
J4 io: Most modern generation with io-homecontrol® – bidirectional, smart home capable, with status feedback and perfect integration into central controls.
 
 
The optional Protect versions (J4 WT Protect / io Protect) have integrated blocking detection and freeze protection, which means that the slats automatically stop in the event of resistance or ice formation - so the system remains protected and functional.

Area of application: external blinds and external blinds
The Somfy J4 series is specially developed for use in external blind systems, external blinds and facade systems.
Through precise slat positioning, these motors enable sensitive regulation of light and shadow.
Depending on the version, they can be integrated into individual, group or radio controls and support automatic linking to sun, wind and weather sensors.
The Protect variants offer additional protection against overload and freezing damage, which makes them particularly suitable for large or free-standing systems on weather sides.
 
 
 
Sustainability meets safety
By professionally reprocessing them, I extend the lifespan of these high-quality block drives - a sustainable alternative to buying new ones.
All motors offered are tested according to GPSR and meet the current requirements for safety and function.
Each motor comes from trustworthy sources or from my own inventory and is only passed on after a successful functional test.
 
 
 
Additional notes
 
 
 
The images shown in the listing are for reference purposes only. Nameplates or housing details may vary as Somfy has changed series markings over the years. The exact motor type is always stated in the respective variant description.
 
 
The motors are offered without accessories as standard; a cable with a STAS3 connector is usually attached to block motors. If you need adapters, shaft couplings or control cables, you can order them separately in the shop - if available - or ask me.
 
 
Cable types:
 Newer models have a pluggable connection cable.
 Older versions usually have a permanently installed, sufficiently long connection cable.
 
 
An instruction manual is usually provided after purchase.

Note on revocation: The used and refurbished components offered have been tested and are functional. A test of the condition and function is only possible when it is not assembled. If the goods are assembled, put into operation or if an attached security label is damaged or removed, this is considered to be use beyond the handling required for testing. In these cases, in the event of a revocation, an appropriate reduction in value may occur in accordance with Section 357 of the German Civil Code (BGB).
