    • Mechanical (activated by door movement)

    • Magnetic (in some advanced versions)

  • Voltage/Current Rating: Typically 24V DC/AC or 110V AC, 2–5A (verify exact specs for your model).

  • Durability: Designed for high cycle counts (100,000+ operations).

  • Material:

    • Housing: Reinforced plastic or metal (zinc/aluminum alloy).

    • Contacts: Silver-plated for reliable conductivity.

  • IP Rating: Usually IP54 or higher (dust and splash resistant).

3. Installation & Compatibility

  • Commonly Used In:

    • Otis, ThyssenKrupp, Mitsubishi, Hyundai, and KONE elevators (compatible with many brands).

    • Passenger & freight elevators.

4. Safety & Certifications
