German Votech filter sensor Votech filter model Votech filter price

Votech filter sensors are sensors that use laser technology for measurement. They consist of a laser, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

Basic principle of Votech filter sensors

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

Votech filter sensor 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 inspection, multiple photoelectric sensors, 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, inspecting whether the bead of adhesive applied by robots to door frames is continuous and has the correct width. In bottling plants, verifying whether bottle caps are correctly sealed, whether the fill level is correct, and that no foreign objects fall into the bottles before capping. On packaging production lines, ensuring that the correct packaging labels are affixed in the correct positions. On pharmaceutical packaging lines, inspecting blister packs of aspirin tablets for broken or missing tablets. At metal stamping companies, inspecting stamped parts at a rate of over 150 pieces per minute, which is more than 13 times faster than manual inspection.

Votech filter sensor classification

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