Safety light curtain sensor applications
Safety light curtain plays a very important role in safe production due to its excellent performance. It can protect workers from the harm of dangerous machines. Safety light curtain can be applied in the following fields.
Mechanical automation: In automated production lines, safety light barriers are used to protect operators from mechanical arms, conveyor belts, and other automated equipment. For example, when an operator accidentally approaches a running mechanical arm, the safety light barrier will detect and immediately stop the operation of the machine to avoid accidents.
Packaging and assembly industry: In packaging and assembly lines, safety light barriers can be used to ensure that workers operate in a safe area and prevent them from contacting dangerous mechanical parts. The safety light barrier forms a “light wall” that immediately stops the relevant mechanical operation once an object passes through.
Material handling: In automated warehouses and logistics centers, safety light barriers are often used to monitor the path area of heavy equipment such as forklifts and automatic transport vehicles. This helps prevent collisions with people or other equipment.
Hazardous area isolation: In chemical plants, power stations, and other places where chemical hazards or high voltage electricity may exist, safety light barriers are used to isolate high-risk areas. They ensure that workers can enter these areas only under safe conditions.
Automatic doors and access control systems: Safety light barriers are also widely used in automatic door control systems. For example, if an automatic door detects a person or object when closing, it will immediately stop the closing process to prevent pinching.
Robot workstation: In the robot operation area, safety light barriers are used to ensure that the robot works in a safe operating environment and protect the surrounding personnel from the risks that may be caused by the robot operation.

Frequently asked questions
What is a safety light curtain sensor?
A safety light curtain sensor has names of safety light barrier, safety light grid and safety light curtain etc, is a safety device used to detect if there are objects or people entering the hazardous area of a machine or equipment. It consists of multiple transmitters and receivers, and when an object enters the plane formed by the light curtain, the sensor will trigger, thereby halting the machine or sounding an alarm.

Knowing how to choose a suitable safety light curtain is a very vital lesson before purchasing and using it. You can refer to this instruction article: Safety Light Curtain: 5 Things You Must Know In 2023.
Is the output of the safety light curtain sensor necessarily a normally closed output?
Yes, that’s right. Normally closed contacts are safer than normally open circuits, and generally you should choose a safety light grid with dual OSSD outputs. The reason is that if one of the OSSDs fails, the other can continue to work to ensure the safety of the user.
How to wire a safety light curtain?
Different manufacturers produced safety light curtains wiring methods might be different, but the wiring method is nearly the same, you can see the below our safety light curtain wiring diagram, if you still have difficulty to wire it correctly, please contact us to get instant support.
