There are high quality Elevator Door Sensors offered by us that are an elevator device that detects a passenger or an object on the doorway which prevents the doors from closing (usually installed for accessibility). They are used in Elevators while entering and exiting the door of the users. It acts as a support system that prevents users from the block. When the doors open completely, the sensor resets the timer that determines when the doors should close. Elevator Door Sensors are very efficient and easy to install.
