The safety light curtain is used to protect people's hands and bodies. Nowadays, the safety light curtain is widely used in hardware machinery, injection molding machines, forging machine tool factories, paper factories, automobile manufacturing factories, etc. The machinery used in these factories will be dangerous, so they must use the safety light curtain sensor. For example, if the safety light curtain sensor is not installed when the paper cutter is running, the manual operation will be wrong, The hand or other parts are likely to be cut if they are placed on it. Such an accident is terrible. However, if the safety light curtain sensor is installed, if the hand is placed on it to block the safety light curtain generated by the residence, the sensor will generate a signal to send a warning to stop the operation of the machine, so as to prevent workers from being injured. Think of the importance of the safety light curtain sensor!

If you don't know, just imagine the elevator we often use. There is an elevator light curtain in it. When our hands or bodies or feet block it, the elevator will automatically open, so as to protect our personal safety. The safety light curtain is the same, but the safety grating is much shorter. It is used in mechanical places. When our hands are in danger areas, Our safety light curtain can react at the first time and let the machinery open to protect our personal safety.

The installation of safety light curtain is very important. Some people cannot ignore safety when using potentially dangerous machinery. The light curtain sensor must be installed to ensure safety! The working principle of the safety light curtain sensor is to form a protective safety grating through a group of infrared beams. When the safety grating is blocked, the photoelectric protection device sends a signal to control the potentially dangerous mechanical equipment to stop working, so as to reduce the possibility of injury to operators in the working environment and effectively protect the personal safety of operators. The illuminator emits several invisible infrared beams, and the light receiver receives the infrared beams from the illuminator, forming a rectangular detection light curtain. The whole set of gratings are detected by beam scanning. Any opaque object larger than a certain size (such as a part of the operator's body, opaque workpieces, etc.) intrudes into the light curtain area, which will cause shading. When the safety grating detects the shading, it will enter the "abnormal" state - interrupt output within 20ms of the response time (for example, the relay will enter the off state from the closed state, the transistor will enter the off state, etc.), so it will be used on many potentially dangerous mechanical equipment to ensure safe use and avoid accidents!
