In 1952, the world's first safety light curtain product appeared, and the advanced photoelectric protection safety device that escorted industrial production was born. In the following decades, the industry prospects and application scope of safety light curtains continued to develop and expand.

Since the birth of industry, workers have begun to work in collaboration with machines. How to avoid mechanical injury accidents in factories? Before the emergence of safety light curtain products, people used traditional safety measures such as mechanical fences, sliding doors, and pull back restrictions. The safety light curtain is more free and flexible, easy to install and maintain, and has the advantage of lower operator fatigue. The safety light curtain, an advanced technology to protect the safety of various dangerous machinery and equipment and surrounding personnel, quickly replaces the traditional The mechanical barrier and other methods of mechanical protection are widely welcomed and loved by the industrial production industry.

The principle of the safety light curtain is to use infrared light to form a protective area. When the light beam is blocked by objects or people, the photoelectric protection device sends out the signal transmission of the invisible infrared light beam to make effective protection or corresponding warning.

Since the development of the domestic safety light curtain industry, the technology and production strength have been greatly improved, but the product quality is uneven, the price is greatly differentiated, and the safety light curtain market is fiercely competitive. Optoelectronic protection devices are being selected for mechanical equipment. At that time, it is necessary for engineers/purchasing friends to carefully screen and choose professional safety light curtains and professional light curtain manufacturers.
