Capacitive proximity sensors

Detection of metallic and non-metallic objects

Sometimes you just need to know what is hidden behind a surface. For example behind a wall or cover, or what is inside in a storage container or shipping container. Capacitive proximity sensors are ideal for level and feed monitoring. From solid material, such as paper or wood, to granules or liquids, they reliably detect the status of the product during the production process and final inspection. Is there something behind that cover? Is the filled package really full? How much paint is still left in the tank? For capacitive proximity sensors, these are easy questions to answer. Capacitive proximity sensors from SICK are never far from the action. Sensing ranges between 1 and 25 mm allow them to be used in nearly all installation situations, making them extremely adaptable for a wide range of applications. These sensors are also remarkably resistant to faults. Impurities, contamination, dust, and airborne spray particles have little effect on them, nor does electromagnetic interference. No wonder they are installed in a wide range of industries, such as food, automotive, or in storage and conveyor systems.
