The proximity sensor has the characteristics of long service life, reliable operation, high repeated positioning accuracy, no mechanical wear, no spark, no noise, strong anti-vibration ability and so on. In the automatic control system can be used as limit, counting, positioning control and automatic protection links. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industries.
Its main functions are as follows:
Test distance
Detect the stop, start and pass position of elevators and lifting equipment; Detect the position of the vehicle to prevent the collision of two objects; Detect the set position of the working machine, the limit position of the moving machine or parts; Detect the stop position of the rotary body and the opening or closing position of the valve; Detect piston movement in the cylinder or hydraulic cylinder.
Size control
Metal plate punching and cutting size control device; Automatic selection and identification of metal parts length; Detect the height of piles during automatic loading and unloading; Measure the length, width, height and volume of the item.
Detect whether the object exists
Check whether there are product packing boxes on the production packaging line; Check for product parts.
Speed and speed control
Control the speed of the conveyor belt; Control the speed of rotating machinery; Control speed and revolutions with various pulse generators.
Count and control
Detect the number of products flowing through the production line; Measurement of the number of revolutions of the high-speed rotating shaft or disk; Parts count.
Detect anomalies
Check the bottle cap; Product qualified and unqualified judgment; Detect the lack of metal products in the packaging box; Distinguish between metal and non-metal parts; Product no label testing; Crane danger area alarm; Escalator starts and stops automatically.
Measurement control
Automatic metering of products or parts; Measuring the pointer range of a meter or instrument to control the number or flow; Detection buoy control surface height, flow; Detecting iron floats in stainless steel drums; Control of the upper or lower range of the instrument; Flow control, horizontal control.
Identify objects
Identify yes and no according to the code on the carrier.
Information transfer
ASI (Bus) connects sensors at various locations on the device to transmit data back and forth in the production line (50-100 meters).
At present, proximity sensors have a wide range of applications in aerospace, industrial production, transportation, consumer electronics and other industries.
