A light curtain is a device consisting of photocells with light sensors. These oppositely positioned curtains create an area that cannot be seen by the human eye. As soon as there is any foreign influence entering this area, they perceive this physical change. With the change, the curtains give a warning signal. Therefore, thanks to this warning, work, and worker safety are ensured.

The light curtain is vital in jobs that require the use of dangerous machinery. Accordingly, while the person continues to work, the interruption between the photoelectric receiver and its data ensures that the device is stopped directly. Accordingly, it is possible to prevent loss of life and property.

How Does a Light Curtain Work?

The light curtain consists of two modules, the receiver, and the transmitter. When an object or light falls between these two modules, the sensor barrier is activated. Then, information is sent to the system in just milliseconds. The active sensor connection here is divided into two parts, electrical and mechanical. The electrical connection can be connected to the system with color-coding, and the mechanical connection can be connected to the system with apparatus and screws.

It is possible to explain the working principle of the light curtain in a simpler way. Accordingly, if the light curtain sensor is interrupted in some way, all electrical operations in that area are automatically stopped. In order for the device with the light curtain to start working again, the factor causing the sensor interruption must be eliminated.

What are the Usage Areas of the Light Curtain?

Light curtain is an advantageous precaution mechanism that companies can take against possible loss of life and property. For this reason, it continues to be widely used in every conceivable sector. At the beginning of the areas where this system is most needed, work areas with risk factors come. Cutting and pressing machines are considered as examples where this system is widely used. Thanks to the measures taken here, involuntary humanitarian interventions and their negative consequences are prevented.
