The proximity sensor has the characteristics of long service life, reliable operation, high precision, no mechanical wear, no spark, no noise, strong anti vibration ability and so on. In automatic control system, it can be used as limit, counting, position control and automatic protection. Is widely used in machine tools, metallurgy, chemical industry, textile and printing industry.

Before we talk about the application of proximity sensors, let's look at some of the main features of the system:

1, inspection distance

Testing equipment, elevator lifting stop, start, through the detection position; the location of the vehicle, to prevent the two object collision detection; set position detection machine, limit position of mobile machine or parts; measure the rotary stop position, the valve open or closed position; detecting cylinder or hydraulic cylinder piston position.

2, size control

Size control device for metal plate punching; automatic selection and identification of metal piece length; automatic detection when loading and unloading pile height; detection items of length and width, height and volume.

3, detect the existence of objects

Check whether there is product packaging box on the production line.

4, speed and speed control

To control the speed of the conveyor belt; to control the rotational speed of the rotating machinery; to control the rotational speed and the rotational speed with various pulse generators.

5, counting and control

Check the number of products flowing on the production line; the number of revolutions of the high speed rotating shaft or disc; the counting of parts.

6, abnormal detection

There is no cap detection; qualified products and unqualified judgment; metal products detection box lack or not; distinguish between metal and non metal parts; products have no signs of alarm detection; crane danger zone; escalator safety automatic start stop.

7, measurement and control

Automatic measurement of products or parts; testing meter, meter pointer range and number or flow control; detection buoy control measuring surface height, flow rate; detection of iron buoy in stainless steel tanks; control instrument in the upper or lower limit; flow control, level control.

8, identify objects

According to the code on the carrier identification.

9, information transmission

ASI (bus) connection equipment in each position sensor in the production line (50-100 meters) in the data transmitted from the other.
