1 Inspection distance

Detect the stop, start and passing positions of elevators and lifting equipment. Detect the position of the vehicle to prevent collision between two objects. Detect the set position of the working machinery and move the limit position of the machine or component. Detect the stop position of the rotating body and the open or closed position of the valve. Detect the movement position of the piston in the cylinder or hydraulic cylinder.

2 Size control

Size control device for metal plate punching and shearing; Automatically select and identify the length of metal parts; Detect the height of the piled materials during automatic loading and unloading. Detect the length, width, height and volume of the item.

3. Check for the presence of objects and whether there are product packaging boxes on the production packaging line. Check for any product parts.

4. Rotational speed and speed control

Control the speed of the conveyor belt; Control the rotational speed of rotating machinery; Control the rotational speed and number of revolutions together with various pulse generators.

5 Counting and control

Detect the number of products flowing on the production line; Measurement of the rotational speed of high-speed rotating shafts or discs; Component counting.

6 Detection Anomaly

Check if there is a bottle cap. Judgment of product qualification and non-qualification Check whether there is a lack of metal products in the packaging box. Distinguish between metal and non-metal parts; Check if the product has a label. Crane danger zone alarm; The safety escalator starts and stops automatically.

7 Measurement Control

Automatic measurement of products or parts; Detect the pointer range of the meter or instrument to control the number or flow rate. The detection buoy controls the height and flow rate of the measurement surface. Detect the iron float in the stainless steel bucket; Control of the upper or lower limit of the instrument range; Flow control, horizontal plane control.

8 Identify Objects

Identify yes and no based on the code on the carrier.

9 Information Transmission

The data back-and-forth transmission of sensors at various positions on the ASI(bus) connected device within the production line (50-100 meters), etc.

The function of a proximity switch is to send out a signal when an object approaches the proximity switch and reaches a certain distance. It does not require external force application and is a contactless master electrical appliance. Its application has far exceeded the travel control and limit protection that limit switches are equipped with. Proximity switches can be used for high-speed counting, detection of the presence of metal bodies, speed measurement, liquid level control, detection of part dimensions, and as contactless buttons, etc.
