Q: What are the advantages of elevator light curtains and safety contact edges? How to select door protection devices for different overseas scenarios? A: Car door protection devices are standard parts of door systems. Overseas buyers often choose between light curtains and safety contact edges. The two differ greatly in cost, protection principle and applicable environments.

  1. Features of two types of door protection devices Light curtains: Multiple infrared beams form an induction barrier to trigger door opening before physical contact. Advantages: comfortable riding experience and low risk of passenger pinching. Disadvantages: sensors are vulnerable to dust and mist interference with higher purchase prices. Safety contact edges: Protection activates after physical collision with obstacles. Advantages: simple structure, low price, strong dust resistance and easy maintenance. Disadvantages: contact is required to activate protection, bringing potential pinching risks.
  2. Suitable overseas scenarios Light curtain priority: High-end hotels, commercial complexes, observation elevators and premium residential buildings in Europe, America and the Middle East with large passenger flow and high comfort requirements; Safety contact edge priority: Economical residential buildings, warehouse freight elevators and budget-limited old elevator renovation projects in Southeast Asia and Central Asia. Combined solution: Dual protection of light curtain + contact edge, mostly adopted in hospitals and nursing homes for the highest safety level.
  3. Foreign trade supply suggestions Three types of products can be exported separately. Multiple specifications of single-layer and double-layer light curtains are available. Explain pros and cons to buyers so they can select solutions based on budget and application scenarios.
