Sensitivity: The working principle of the safety light curtain is that the infrared emitting tube and the infrared receiving tube work one-to-one to form an infrared light protection plane. Once an obstacle occurs, the triggering action is very short (millisecond level), and the corresponding signal can be When delivered to the control point in time, the control machine stops immediately to ensure the safety of the staff. Therefore, the principle of ir light curtain gives better sensitivity;
What is the role of the projector in the protection of the light curtain?
The light curtain in the light curtain safety barrier plays the role of protecting the safety of the equipment. When a foreign object enters the protection net, when light is blocked by the object, through the internal control circuit, the light receiver circuit immediately responds.
1) What is the working principle of the safety light curtain sensor?
When no object passes through the light curtain, the grating light curtain signal can be received normally, the green indicator light is normally on, the fault indicator light is off, and the device starts normally.
2) When a person or an object passes through the safety light barrier, the light is blocked. The grating sensor will transmit this signal to the signal controller. After the safety light curtain controller receives the signal, the red light of the fault indicator turns on and the device It will stop the operation, thereby starting to protect the personal safety of personnel.
