The Positive-Operation Door Contacts manufactured by Schmersal are designed specifically for elevator safety applications. These contacts are used to monitor whether the lift door is correctly closed or locked before allowing the elevator to operate.
The system works with a positive-break mechanism, ensuring that the electrical circuit is safely opened when the door is not properly secured. This fail-safe design is essential for preventing elevator movement when doors are open or improperly locked.
Available in multiple versions, these door contacts can be adapted to various elevator configurations and locking mechanisms, including hook bar monitoring. They are tested and certified according to recognized European and American safety standards, ensuring dependable performance in modern lift installations.
