Overview Almost 90% of all collisions occur in the lower part of a door. The TÜV-certified EFA-TLG® infrared light grid is a self-monitoring safety system designed to prevent such collisions by monitoring the door closing level directly within the lateral door guide. The system generates an almost flat infrared light grid that detects even the smallest obstacles without contact. If an obstacle is detected, the closing movement is immediately stopped or prevented from starting, protecting people, doors, vehicles and materials.
EFA-TLG® at a glance - Close optical monitoring of the door closing level up to a height of 2,500 mm
- Risk-adapted responses to detected objects (people, vehicles, materials)
- TÜV-certified safety system
- Complies with and exceeds applicable safety standards
How it works The EFA-TLG® is installed directly in the lateral door guide and operates as a completely self-monitoring safety device. An almost flat infrared light grid formed by intersecting beams detects obstacles in the closing area without physical contact. On detection, the system either prevents initiation of the closing movement or immediately stops an ongoing closing cycle. This risk-adapted response protects personnel and property while maintaining door functionality.
Benefits - Non-contact detection of very small obstacles
- Immediate, risk-adapted reaction on detection
- Integration into door guide for space-efficient installation
- Reduces collisions and associated damage to doors and transported goods
