What is the principle of thapplication of light curtain sensor 2024-07-16 00:41:19 internet

Optoelectronics safety devices are launched to protect the light curtain by launching infrared rays. When the light curtain is blocked, the device sends a shielding signal to control the stop work with potential dangerous machinery and equipment to avoid safety accidents.
Light curtain sensor price
The lowest price is 680 yuan, and the highest price is 3250 yuan.The light curtain sensor is a photoelectric safety device through infrared to protect the light curtain. When the light curtain is blocked, the device sends out a shading signal to control the stop work with potentially dangerous mechanical equipment to avoid safety accidents.
Application of light curtain sensor
It meets the IEC61496-1/2 standard of the International Electrician Society. It adopts a mature synchronous infrared scan, excellent optical performance and 2.5 ° divergent angle, which is easy to accurate and maintain. The shape is small.20/40mm of a variety of specifications resolution, the protection height range is 4-128cm width, and the electrical connection. 4-needle M12 connector.
Light curtain sensor wiring
The wiring of the light curtain sensor is divided into two types, one is not connected to the controller, and the other is an external controller. The external controller is very strict.
Light curtain sensor principle
1. When there is no invasion of an object in the protection area, the receiver of the sensor is in a state of light. At this time, the communication indicator (red light) of the receiver should be extinguished, and the transmitting indicator (yellow light) is lit.The work switch of the device can operate normally.2. When an object (not less than the minimum detection body or resolution) invades the protected area, the red indicator of the receiver will be lit (maybe the receiver is in a shading state or the light communication is covered). ThisThe protected equipment is controlled and is in a state of compulsory pause.3. When the invading object is withdrawn from the protected area, the light curtain sensor will return 1. State, and the device will continue to work.
