IPF switch German IPF model IPF price

IPF switch, also known as a displacement switch, is a type of switch used to sense the distance to an object to perform a preset function, and has been widely applied. Main products include mobile phone proximity switches and long-distance measurement switches, applied in smart belts. Proximity switches can be classified into optical proximity switches, infrared proximity switches, ultrasonic proximity switches, etc., based on their working principles. Most proximity switches used in mobile phones are infrared proximity switches, which have an infrared emitting tube and an infrared receiving tube. When the infrared ray emitted by the emitting tube is received by the receiving tube, it indicates that the distance is close, and the screen needs to be turned off to prevent misoperation. When the receiving tube does not receive the infrared ray emitted by the emitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity switches are similar; they also determine the distance by emitting and receiving some kind of substance, such as ultrasonic waves or light pulses.

IPF switch basic principle

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

IPF switch application areas

The low cost and ease of use of vision switches 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 switches 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 whether foreign objects have fallen into the bottles 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.

IPF 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. Optical switches are among the most produced and widely used switches, playing a very important role 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.
