Proximity Switches and Sensors

Photoelectric Proximity Switch

The most affordable photoelectric solution is the energetic proximity sensor. A light-colored surface reflects more light than a dark one and can therefore be detected from a greater distance away. To achieve similar results with a dark surface, the sensitivity of the sensor must be increased as light-colored objects against dark backgrounds are easier to detect.

Capacitive Proximity Sensor

Capacitive proximity sensors detect all objects. 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. The sensing range increases with the dielectric constant of the object to be detected.

Inductive Proximity Sensors

Inductive proximity sensors offer reliable detection in nearly all areas and industry sectors. They detect metal targets and are suitable for diverse applications due to their variety of housing shapes and sizes.

Magnetic Proximity Sensors

The defining feature of magnetic proximity sensors is their long sensing ranges, even with small housing sizes. They detect magnetic objects, usually permanent magnets, which are used to trigger switching. As magnetic fields can penetrate many non-magnetizable materials, switching can be triggered even through other materials. By using magnetic conductors (such as iron) the magnetic field can also be transported relatively long distances for various tasks, such as taking a signal out of an area of high temperature.
