Introduction

Detection of metallic and non-metallic objects

Sometimes you need to know what is hidden beneath a surface. Behind a wall, for example, inside a storage container, inside a shipping container, or behind a cover. Capacitive proximity sensors are ideal for level and feed monitoring. From solid material, such as paper or wood, to granules or liquids, they can be relied upon to detect what is happening in the production process and during final inspection. Is there something behind that cover? Is the finished package really full? How much paint is still left in the tank? For capacitive proximity sensors, these are easy questions to answer. SICKs capacitive proximity sensors 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 interference. 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 and automotive, or in storage and conveyor systems.

  • M18 - Cylindrical housing
