Elevator Photocell - Smart Elevator Door Sensor

WHAT IS AN ELEVATOR PHOTOCELL?

The elevator Photocell system is also known by many names such as elevator door sensor , elevator door photosensor , elevator infrared curtain , or elevator cabin door curtain , even called PHOTOCELL bar . This variety of names for an elevator safety device demonstrates the richness and variety of its applications.

The elevator photocell is not only a conventional safety device but also considered a smart sensor integrated at the elevator door. Its main task is to detect obstacles and ensure that the elevator door operates stably. With such diverse names, elevator photocells proactively control problems related to elevator doors, helping to protect passenger safety and ensure elevator performance.

OPERATIONAL PRINCIPLES OF ELEVATOR PHOTOCELL

On both sides of the elevator cabin door , two elevator Photocell bars are installed with each bar about 2000mm long. As mentioned before, the elevator sensor is a protective device, specialized in detecting obstacles at the elevator door. Therefore, installing this device at the elevator door helps ensure comprehensive protection of the elevator's access range.

When the elevator starts operating and the elevator door opens or closes, the elevator photocell or elevator door sensor will be activated. During this process, the sensor will perform a scan, detecting any obstacles that may appear at the elevator door. In case no obstacle is detected within the specified period of time, the elevator will continue to operate normally. This ensures the safety and performance of the elevator during operation.

When the elevator door sensor detects an obstacle, the elevator will temporarily stop operating and the photocell will emit a warning signal. Operation will resume only after the problem is resolved and there are no longer any obstructions in front of the elevator door.

If there is an obstacle at the elevator door, the elevator Photocell system will immediately detect it and the elevator will automatically open the door, waiting until the problem is resolved before continuing to operate. This ensures that the elevator only resumes operation when all safe conditions are restored.

POPULAR TYPES OF ELEVATOR PHOTOCELLS

There are two main types of elevator photocells , designed as point and bar types, to serve special purposes in ensuring elevator safety and performance. Below is a detailed description of both types of elevator photocells - elevator door sensors :

Both types of elevator door sensor photocells play an important role in ensuring elevator safety by preventing doors from closing in the presence of obstacles, minimizing the risk of accidents and unwanted collisions. The choice between point and bar depends on the specific requirements of the elevator system and the installation environment.

STRUCTURE AND BASIC TECHNICAL SPECIFICATIONS OF PHOTOCELL ELEVATOR

What is the structure and basic specifications of the elevator Photocell ? Let's learn with SANKYO Elevator through the following content:

Structure of elevator door sensor - PHOTOCELL

Elevator door sensor - elevator photocell is composed of 3 main parts ( bar Photocell form ) including:

• Two receiver bars placed on both sides of the elevator cabin door frame emit infrared rays to control elevator obstacles. The two receiver bars of the elevator photocell are installed in the cabin door or installed at both ends of the cabin door.

• Power supply: The power supply is where electricity is stored as well as where the photocell's operating equipment is installed. This is an important part of the elevator door sensor that helps it operate most accurately, also known as the infrared transceiver circuit.

• The wiring system provides electrical connection to photocell operations.

Basic technical specifications of elevator door sensor - elevator PHOTOCELL

Our elevator door sensors are manufactured to a variety of specifications, optimized to suit each specific elevator type. Below are some parameters that SANKYO Elevator has compiled for your reference, to provide an overview of the product's technical characteristics:

• The height of the elevator photocell will include sizes such as: 2m, 1.2m, 1m;

• The power source used by the infrared blinds is 220V AC with a frequency of 50Hz;

• The elevator sensor's response signal is 0V and 24V DC;

• Elevator photosensitive installation location: Along both sides of the cabin door or in the elevator door frame;

• Uses: Detects obstructions at the door, gives a warning signal to the electrical cabinet and the closed door will open and the elevator will temporarily stop its journey. This helps keep a safe distance from users, especially young children, the elderly, disabled people, and pregnant women.

IS IT NECESSARY TO INSTALL AN ELEVATOR SENSOR - ELEVATOR PHOTOCELL?

The installation of photocell - elevator door sensor plays an important role in ensuring the safety and performance of the elevator system. Here are some reasons that elevator photocell installation is considered necessary:

Safety for passengers

Photocell helps detect obstacles at elevator doors, preventing the doors from closing when people or objects are entering or exiting the elevator. This helps avoid the risk of collision and injury to passengers.

Prevent crashes

Photocell plays an important role in preventing incidents when there are obstacles within the elevator door, helping to protect people and property.

Comply with safety standards

Installing photocells is a measure to comply with safety regulations, helping the elevator system meet technical requirements and standards, while keeping the entire system operating safely and efficiently.

Guaranteed performance

Photocell helps ensure that elevator doors only operate when there are no obstructions, helping to maintain operational efficiency and avoid unnecessary wear and tear on the system.

Legal proof and insurance

The installation of elevator photocells is a necessary legal proof, helping to ensure legal compliance and supporting the insurance assessment process.

In short, installing elevator photocell - elevator door sensor is not only a good choice for safety but also helps the elevator system operate effectively and reliably.

In short, elevator Photocell - elevator door sensor plays an important role in modern elevator systems. They not only increase elevator safety but also ensure users' lives by preventing unfortunate incidents. Therefore, it is recommended to regularly check the operation of elevator photocells in the home to detect and resolve problems promptly.
