BALLUFF Proximity Switch product Description

The BALLUFF proximity switch is a position switch that can be operated in mechanical contact with moving parts. When the object approaches the sensing surface of the switch to the working distance, the switch can be operated without mechanical contact and any pressure is applied to drive the AC. Or DC appliances or provide control instructions to computer devices.

The proximity switch is a switch type sensor (ie, no contactless switch), which has the characteristics of a stroke switch and a micro switch, and has sensing performance, reliable operation, stable performance, fast frequency response, long application life, and resistance. It has strong interference capability, and is waterproof, shockproof and corrosion resistant. Products are inductive, capacitive, Hall, AC, DC. The proximity switch, also known as the non-contact proximity switch, is an ideal electronic switching sensor. When the metal detector approaches the sensing area of the switch, the switch can be contactless, without pressure, without sparks, and quickly emit electrical commands, accurately reflecting the position and stroke of the moving mechanism, even for general stroke control, its positioning accuracy, operation Frequency, service life, ease of installation adjustment, and ability to withstand harsh environments are not comparable to conventional mechanical travel switches. It is widely used in machine tools, metallurgy, chemical, textile and printing industries. It can be used as a limit, counting, positioning control and automatic protection in the automatic control system. The proximity switch has the characteristics of long service life, reliable operation, high repeatability, no mechanical wear, no spark, no noise, strong anti-vibration capability. So far, the application range of BALLUFF proximity switches has become more and more extensive, and its own development and innovation speed is extremely fast.

2. The main function of the proximity switch
2.1 Inspection distance detection of elevator, lifting equipment stop, start, pass position; detect the position of the vehicle to prevent collision detection of two objects; detect the set position of the working machine, move the limit position of the machine or component; detect the stop position of the rotating body , the opening or closing position of the valve; detecting the moving position of the piston in the cylinder or the hydraulic cylinder.
2.2 Size control The size control device for punching and shearing of metal plates; automatically select and identify the length of metal parts; detect the height of the pile during automatic loading and unloading; and detect the length, width, height and volume of articles.
2.3 Check the presence of objects Check whether there are product packaging boxes on the production packaging line; check for product parts.
2.4 Speed and speed control Control the speed of the conveyor; control the speed of the rotating machine; control the speed and number of revolutions together with various pulse generators.
2.5 Counting and Control Detect the number of products flowing on the production line; the number of revolutions of the rotating shaft or disk at high speed; the count of parts.
2.6 Detect abnormality detection bottle caps; product qualification and non-conformity judgment; test the lack of metal products in the packaging box; distinguish metal and non-metal parts; product with or without signage detection; crane danger zone alarm; safety escalator automatic start and stop .
2.7 Automatic measurement of measurement products or parts; detection of pointer range of gauges and meters; control number or flow rate; detection of buoys to control the height of the measuring surface, flow rate; detection of iron buoys in stainless steel barrels; control of upper or lower limit of meter range; flow rate Control, level control.
