Elevator Door Sensor & Light Curtain

Elevator Door Sensor / Light Curtain

The Elevator Door Sensor / Light Curtain is an essential safety device designed for automatic elevator doors. It helps detect passengers, objects, or obstacles in the elevator doorway and prevents accidental door closing while the entrance is occupied. Using reliable infrared sensing technology, the system creates a protective detection area across the elevator entrance for safer and smoother passenger movement.

Designed for passenger elevators and other automatic lift applications, this elevator door sensor provides dependable performance for residential buildings, apartments, offices, hotels, hospitals, shopping complexes, and commercial properties. It can be used for new elevator installations as well as modernization and replacement projects, subject to compatibility with the elevator door operator and control system.

Elevator Door Sensor – Reliable Infrared Safety Detection

The Elevator Door Sensor uses multiple infrared beams across the elevator entrance to monitor the doorway. When a passenger or object interrupts the detection area, the sensor sends a signal to the elevator door control system so that the automatic door can remain open or reopen as required.

This helps reduce the possibility of passengers, luggage, trolleys, or other objects being caught by closing elevator doors. The light curtain system provides a wider detection area compared with basic single-point detection systems, making it a practical safety solution for modern automatic elevators.

How the Elevator Door Sensor Works

The light curtain normally consists of transmitter and receiver sensor strips installed on or near the elevator door entrance. Infrared beams pass between the sensor units and continuously monitor the doorway.

When the doorway is clear, the elevator door system can operate normally. If a person or object enters the detection area and interrupts the infrared beams, the sensor communicates with the door control system. Depending on the elevator controller and door operator configuration, the door can remain open or reopen to help protect the passenger or object.

This automatic detection process is especially useful in elevators with frequent passenger movement.

Applications

The Elevator Door Sensor / Light Curtain is suitable for a wide range of elevator applications, including residential apartment elevators, office building lifts, commercial elevators, hotel elevators, hospital lifts, shopping complex elevators and other passenger elevator systems.

It is particularly useful where automatic elevator doors operate frequently and reliable passenger detection is important.

Suitable for New Installation and Modernization

This elevator safety sensor can be considered for both new elevator projects and existing elevator modernization work. For replacement applications, the existing door operator, controller, power requirements, wiring and interface should be checked before installation.

Correct compatibility is important because elevator door systems may use different electrical connections, control signals and operating configurations.

Installation & Compatibility

Installation should be carried out by a qualified elevator technician. Before installation, the technician should verify the elevator door operator type, controller interface, operating voltage, sensor mounting arrangement and wiring requirements.

Proper sensor alignment is important for reliable operation. After installation, the complete detection area and door reopening function should be tested before the elevator is returned to normal passenger service.

Compatibility should always be confirmed according to the specific elevator system before purchase or installation.

Safety & Maintenance

The Elevator Door Sensor is an important component of an automatic elevator door safety system. The sensor surface should be kept clean and free from dust, obstruction or physical damage. Periodic inspection during elevator maintenance can help ensure that the sensor remains correctly aligned and responsive.

Any damaged cable, sensor strip, connector or related component should be inspected by a trained elevator technician. Safety devices should not be bypassed or modified without proper technical evaluation.
