Before we talk about the proximity sensor application, let's take a look at some of the main features it has:
1, inspection distance
Detecting the stop, start and pass position of the elevator and lifting equipment; detecting the position of the vehicle to prevent the collision of two objects; detecting the set position of the working machine, moving the limit position of the machine or component; detecting the stop position of the rotary body, the valve Open or close position; detect the position of the piston in the cylinder or hydraulic cylinder.
2, size control
The size control device for metal plate punching; automatically selects and identifies the length of the metal piece; detects the height of the pile during automatic loading and unloading; and detects the length, width, height and volume of the article.
3. Is there any presence of the detected object?
Detect whether there is a product packaging box on the production packaging line; check for product parts.
4, speed and speed control
Control the speed of the conveyor; control the speed of the rotating machine; control the speed and number of revolutions with various pulse generators.
5, counting and control
Detect the number of products flowing through the production line; the number of revolutions of the rotating shaft or disk at high speed; the count of parts.
6, detection abnormalities
Check the presence or absence of the bottle cap; judge the product's pass and fail; test the lack of metal products in the package; distinguish metal and non-metal parts; product with or without signage detection; crane danger zone alarm; safety escalator automatically start and stop.
7, measurement control
Automatic metering of products or parts; detecting the range of pointers of meters and meters and controlling the number or flow; detecting buoys to control the height of the measuring surface, flow rate; detecting iron buoys in stainless steel barrels; controlling the upper or lower limit of meter range; flow control, horizontal control.
8, identify the object
Identify the right and wrong according to the code on the carrier.
9, information transmission
The ASI (bus) connects the sensors at various locations on the device to and from the data line in the production line (50-100 meters).
At present, proximity sensors are widely used in aerospace, industrial production, transportation, consumer electronics and other fields. Here are some typical application scenarios to open up for your application in proximity sensors. Some ideas.
