Valosäleet

Valosäleet, also known as light curtains or laser curtains, are a type of optical sensor system used for detecting the presence or absence of objects. They are composed of an array of infrared light beams emitted by a transmitter and detected by a receiver. When an object breaks one or more of these beams, the system registers the interruption and triggers a response.

The primary application of valosäleet is in safety systems. They are commonly found in industrial settings, such as on conveyor belts, robotic work cells, and automated machinery, to prevent accidents by stopping equipment if a person or object enters a hazardous area. In a similar vein, they are used in automatic doors, where they detect the presence of people or objects to prevent the doors from closing on them.

Valosäleet can also be employed for counting objects passing on a conveyor, controlling automated processes based on the presence of items, or even in security applications for detecting unauthorized entry into restricted zones. The density and number of light beams can be adjusted depending on the required level of detection precision and the size of the objects to be detected. The technology offers a reliable and non-contact method for object detection, contributing to enhanced safety and automation in various fields.
