New 3mm diameter capacitive displacement sensor is one of the smallest triaxial sensors in the world

20 September 2022

Micro-Epsilon has introduced two new sensors to its capaNCDT range of non-contact capacitive displacement sensors.

The capaNCDT CSE01 and capaNCDT CSE025 are extremely compact sensors that provide a measuring range of 0.1mm and 0.25mm respectively. With a diameter of 3mm and a length of 15.6mm, the capaNCDT CSE01 is one of the smallest triaxial sensors in the world. 

The CSE025 has a diameter of 4mm and a length of 16.1mm, making both sensors ideal for distance, position and thickness measurement tasks in confined installation spaces.

As well as being small, the new sensors offer extreme measurement performance with resolutions of just 0.08nm and 0.188nm for the respective ranges. The two new sensors complement Micro-Epsilon’s comprehensive portfolio of 30 standard capacitive displacement sensors with measuring ranges from 0.05mm to 10mm. Capacitive sensors are available in a range of form factors from cylindrical, threaded and flat housings and all feature unsurpassed resolution and accuracy with high signal stability. 

Applications range from vacuums and clean rooms, where sub-nanometer accuracy is possible, to industrial applications in harsh environments, where the sensors offer sub-micron accuracy. The sensors are sufficiently robust to withstand extreme temperature conditions (low to high, -50°C to +200°C) while providing the best possible temperature stability. 
The sensors are also extremely resistant to magnetic fields, which means safe and trouble-free operation is possible in the vicinity of magnets. Furthermore, due to the triaxial technology, replacing the sensors and controller is possible without requiring additional calibration.

The capaNCDT CSE01 and CSE025 have an integrated cable with a length of either 1.4m or 2.8m and are compatible with all Micro-Epsilon controllers in the DT61xx, DT62xx and DT65xx series.
