Capacitive proximity sensors bb No physical contact with the object to be detected. bb High operating rates. bb Solid-state product, no moving parts (service life not related to number of operating cycles). bb Detection of any object irrespective of material or conductivity, for example: metals, minerals, wood, plastic, glass, cardboard, leather, ceramic, fluids, etc. Operating principle Electrical field An electrical field is created between 2 electrodes on the front face of the sensor. These electrodes constitute a capacitor with a capacitance of: C = e0 * er * A/d where:...

Capacitive proximity sensors General (continued) In order to ensure that customers can make reliable product comparisons and selection, the standard IEC 60947-5-2 defines various sensing distances, such as: Reference axis Standard target Assured operating distance Nominal sensing distance (Sn) The rated operating distance for which the sensor is designed. It does not take into account any variations (manufacturing tolerances, temperature, voltage). Effective sensing distance (Sr) The effective sensing distance is measured at the rated voltage (Un) and the rated ambient temperature (23 °C ±5...

Capacitive proximity sensors General (continued) Terminology (continued) All our sensors incorporate a sensitivity adjustment potentiometer. This enables the sensitivity of the sensor to be adjusted to suit the type of object to be detected. Depending on the sensor version, the sensitivity adjustment potentiometer is either mounted on the side or the rear. The sensors are factory preset for nominal sensitivity. Depending on the application, adjustment of the sensitivity could be necessary as follows: -- increasing the sensitivity for objects which have a weak influence (weaker): paper,...

General (continued) Capacitive proximity sensors OsiSense XT bb Electromagnetic interference The sensors undergo electromagnetic interference testing in accordance with the recommendations of standard IEC 60947-5-2 (electrostatic discharges, radiated electromagnetic fields, fast transients, impulse voltages). bb Thermal influences It is advisable to remain within the values stated on the characteristic pages so as to avoid sensing distance drift and possible incorrect operation of the sensor. bb Chemical agents To ensure a long service life, it is essential that any chemicals coming into...
