On the basis of detecting the light curtain, the infrared measuring light curtain can detect the existence of objects by analyzing the internal electric pair data, and can accurately measure the specific size and movement speed of objects passing through the detection light curtain; The distance between two points can be measured horizontally. It is generally applicable to various object size measurement, speed measurement, blanking size, product sorting, diameter measurement, tension detection control, center positioning control, coil offset detection, edge offset detection, cutting offset detection, etc; Therefore, the subject detection light curtains of are: counting light curtain, spraying light curtain, speed measurement light curtain, object size measurement grating, correction light curtain, centering light curtain, vehicle separator, spraying grating, etc.

Features of detection light curtain:

1. High sensitivity detection: high sensitivity ≤ (n+1) * 0.1ms;

2. It has good anti-interference ability against electromagnetic interference, stroboscopic light, welding arc light, fluorescent light, sunlight and other light sources, especially PLC interference, with double circuit guarantee;

3. Anti loose and gold-plated aviation plugs are used to ensure reliable connection;

4. Reverse connection protection and output short circuit protection;

5. The wide working voltage range DC10V-DC30V can work reliably;

6. Good anti-seismic and dust-proof performance (the end cover and filter are all provided with gaskets);

7. It has self check fault alarm function. Automatically detect faults, ignore (shield) the beam with problems, and still keep working normally, while outputting alarm signals.

8. It can be customized for personal protection, object detection, dimension measurement, and other special purposes.
