What constitutes a safety light curtain

The safety light curtain consists of two parts: a light projector and a light receiver. After the emitted infrared light is modulated, it is received by the light receiver, so that an object enters the protection network. When an object blocks the object, the light receiver circuit responds immediately, that is, outputs a signal for machine tools such as punches and presses. Wait for emergency braking.

Safety light curtains have a very wide range of applications. For example, if a contact type safety protection door is installed on a stamping equipment that requires continuous feeding of materials, the operator needs to open the safety protection door frequently, which not only increases the workload of the operator, but also Will reduce production efficiency.

　　 Therefore, the use of gratings and light curtains is a better choice. When the operator feeds, as long as any part of the body blocks the light, the machine will enter a safe state without causing harm to the operator.

The density of the beam determines the size of the body that can be detected. This is the light curtain. According to ergonomics data, the diameter of an adult's finger is no less than 14mm, the thickness of the palm is no less than 30mm, and the wrist is no less than 40mm. For example: If the optical axis spacing of the light curtain used is 40mm and the optical axis diameter is 20mm, its resolution If it is 40+20=60mm, then the hand value, palm, wrist and arm can all pass through the light curtain without being noticed. So if you want to get higher security, you need to use a higher resolution to achieve.

When using gratings and light curtains, there are certain requirements for installation. This prevents people from bypassing the grating and light curtain to enter the dangerous area, and also avoids the reflection of the surface near the grating and light curtain, so that the receiver can receive the reflected light but cannot output Safety switch signal. In addition, there are certain requirements for the use environment of gratings and light curtains. If the environment is too dusty, it will affect the emission of light, and then affect the use of light curtains.

　　 The above is a simple explanation about the safety light curtain, I hope it will be helpful to our customers to understand the safety light curtain!
