Innovative all-rounders. Capacitive sensors can detect metallic, non-metallic, transparent, opaque, liquid and solid substances reliably without the need for contact. These properties make them true «all-rounders», which are used in a many different industrial applications. The ability of the measuring field to penetrate non-conductive materials is particularly advantageous for measuring filling levels. Capacitive sensors can be installed outside of a container to detect a filling level inside. This protects the sensor from aggressive media and prevents contamination of high-quality...

Solutions customized for each customer No range of products will ever be large enough to provide the optimal solution for every application. Often within an application, there are requirements that move in a completely ­ new direction and cannot be fulfilled to the extent desired by the existing solutions in the market. This is why our development engineers work closely with our customers. Sensors customized for each customer are continuously being created while searching for the optimal solution to specific requirements. The range extends from special mechanical housings all the way to...

Electrical and mechanical definitions Sensing face Admissible lead lengths Output indicator For proximity switches large lead lengths signify load capacitance of the output and increased influence of interference signals. Lead lengths >5 m should, if possible, be avoided. The LED indicates the current The size of the sensing face is defined by the electrodes. The output. larger the measuring electrode, the larger the electrical field and the greater the sensOil resistance Sensors with all-metal housing ing distance. Electrical and mechanical definitions Most capacitive sensors come standard...

Definition of sensing distance The international standard EN 60947-5-2 defines sensing distance as follows: sensing distance is the distance at which a standard target moving toward the sensing face of a proximity switch causes a signal change. The sensing distance of capacitive sensors depends on the following factors - Sensor diameter - Sensor design (with/without GND electrode) - Material of the medium to be detected - Size of the approached body Sensing face Standard target Predefined part used for comparative measurement of sensing distances and scanning ranges. The standard target is...
