BALLUFF switch German BALLUFF model BALLUFF price

BALLUFF switch is the direct source of information for the entire machine vision system, mainly composed of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of the vision sensor is to acquire the rawest images sufficient for the machine vision system to process. Image sensors can use laser scanners, line-scan and area-scan CCD cameras or TV cameras, as well as newly emerging digital cameras.

Basic principle of BALLUFF switch

Vision sensors have thousands of pixels that capture light from an entire image. The clarity and fineness of the image are usually measured by resolution, expressed in pixel count. Some vision sensors provided by Banner Engineering Company can capture 130 ten thousand pixels. Therefore, regardless of whether the target is meters or centimeters away, the sensor can "see" a very detailed target image. After capturing the image, the vision sensor compares it with reference images stored in memory to make an analysis. For example, if the vision sensor is set to identify machine parts correctly fitted with eight bolts, the sensor knows to reject parts with only seven bolts, or parts with misaligned bolts. In addition, regardless of where the machine part is located in the field of view, and regardless of whether the part rotates within a 360 degree range, the vision sensor can make a judgment.

BALLUFF switch application areas

The low cost and ease of use of vision sensors have attracted machine designers and process engineers to integrate them into various applications that previously relied on manual labor, multiple photoelectric switches, or no inspection at all. Industrial applications of vision sensors include inspection, gauging, measurement, orientation, defect detection, and sorting. The following are just some application examples: In automobile assembly plants, inspect whether the bead of glue applied by robots to the door frame is continuous and has the correct width. In bottling plants, verify whether bottle caps are correctly sealed, whether the filling level is correct, and that no foreign matter falls into the bottle before capping. On packaging production lines, ensure that the correct packaging labels are affixed in the correct positions. On pharmaceutical packaging production lines, inspect blister packs of aspirin tablets for broken or missing tablets. In metal stamping companies, inspect stamped parts at a speed of over 150 pieces per minute, which is more than 13 times faster than manual inspection.

BALLUFF switch classification

Photosensitive switches are one of the most common types of vision switches. They come in many varieties, mainly including: phototubes, photomultiplier tubes, photoresistors, phototransistors, solar cells, infrared switches, ultraviolet switches, fiber-optic photoelectric switches, color switches, CCD, and CMOS image switches, etc. Optical switches are among the most produced and widely used switches, occupying a very important position in automatic control and non-electrical electrical measurement technology. The simplest photosensitive switch is the photoresistor, which generates current when photons strike the junction. Switches should be packaged in anti-static bags. During use, avoid using them in humid environments, and pay attention to surface damage and contamination levels, as these will affect the photocurrent.
