How can you distinguish between automatic and manual elevator doors?

The distinction between automatic and manual elevator doors primarily lies in the mechanism by which they open and close. Automatic doors are designed to operate without the need for passenger intervention; they typically use sensors to detect when a person is approaching the elevator and will slide or swing open automatically. This enhances convenience and accessibility, allowing for a smoother, more efficient entry and exit.

In contrast, manual doors require passengers to physically push or pull them to open. This type of door often involves more physical effort and may be found in older elevators or in specific applications where automatic systems may not be practical.

While aspects such as color, design, materials, or size may vary between different elevator installations, these characteristics do not fundamentally determine whether an elevator door is automatic or manual. The operational method is the key distinguishing factor.
