FAQ

What are the sizes and shapes of safety light curtains？

Safety light curtains come in various sizes and shapes to meet the specific needs of different industrial applications. Some common characteristics regarding the sizes and shapes of safety light curtains include:

Sizes:

1．Height: Safety light curtains can range in height from a few centimeters to several meters. The height is chosen based on the size of the area that needs to be guarded.

2．Width: Similarly, the width of safety light curtains can vary from a narrow strip to several meters wide. The width is determined based on the size of the potential hazard zone and the movement of objects or personnel in that zone.

3．Beam Spacing (Resolution): The spacing between individual beams, also known as the resolution, can be adjusted. Narrower beam spacing provides a finer detection zone and allows for the detection of smaller objects. Beam spacing typically ranges from a few millimeters to several centimeters.

Shapes:

1．Straight (Rectangular): The most common shape for safety light curtains is a straight, rectangular configuration. These are typically mounted vertically along a machine's access points to protect operators or other personnel from hazardous moving parts.

2．Curved: Curved safety light curtains are designed to conform to the shape of curved machine guards or other non-rectangular applications. They provide a continuous detection zone along the curved surface.

3．Customizable: Many manufacturers offer customizable options for safety light curtains. This allows customers to specify the exact size, shape, beam spacing, and other parameters to meet their specific application requirements.

It's important to note that the size and shape of a safety light curtain should be selected based on a thorough assessment of the hazard zone, the movement of personnel and objects in that zone, and the specific safety requirements of the application. Consulting with a safety expert or the manufacturer of the safety light curtain can help ensure that the selected system provides adequate protection for the intended application.
