**Somfy Anti-Blocking System (ABS) – Product Description**
The **Somfy Anti-Blocking System (ABS)** is an advanced safety feature designed to protect motorized awnings, roller shutters, and blinds from jamming or damage caused by obstructions. Using intelligent detection technology, it automatically reverses movement when resistance is detected, ensuring smooth operation and preventing mechanical failures.
### **Key Features:**
✔ **Obstruction Detection** – Sensitive torque monitoring stops and reverses movement upon contact
✔ **Auto-Reverse Function** – Immediately retracts when blockage occurs
✔ **Adjustable Sensitivity** – Customizable settings for different load types
✔ **Seamless Integration** – Works with **Somfy LT, ST, and IO motors**
✔ **Weatherproof Design** – Suitable for indoor and outdoor use
✔ **Energy Efficient** – Low power consumption with no impact on motor performance
### **Technical Specifications:**
- **Compatibility**: Somfy 24V/230V motors (LT50, ST30, etc.)
- **Response Time**: <0.5 seconds
- **Load Detection Range**: 5–50N (adjustable)
- **Operating Temperature**: -20°C to +60°C
- **Protection Rating**: IP44 (splash-resistant)
### **Applications:**
✓ Awnings & pergolas
✓ Roller shutters & blinds
✓ Projection screens
**Installation Note**: Requires professional setup for optimal sensitivity calibration.
**Part Number**: ABS-SOM-01 (verify for specific models)
