Somfy J4 "WT-Protect" series mid-mounted motors

J4 WT Protect series - Premium electronics with external venetian blind protection

Compared to the classic mechanical drive, the advantages of the J4 WT drive are

• Remote adjustment of the end positions (with or without adjustment cable)
  
  
• Switch sensor active in both running directions
  
  
• Parallel switching

Blockage detection additionally enhanced with 2 new functions for the protection and aesthetics of the blind:

• Obstacle detection and freeze protection in the OPEN direction with a unique selling point: after detecting the blockage, the drive stops and the elevator hinges are then automatically relieved of load
  
  
• The J4 WT Protect offers automatic adjustment of the fixed upper end position and thus prevents the raised slat pack from becoming visible outside the cover after a few weeks.
  This reliably compensates for the normal changing winding behavior of the elevator tapes
