Profile Sensors

Precision optical instruments to detect punctual imperfections in all kinds of wires, cables and filaments.


Designed to satisfy today’s demanding quality control standards.

Our technology is based on light intensity shadow measurements and employs LED sources instead of lasers. Since it requires no moving parts, it is more reliable and benefits from a longer lifespan.


Compared to conventional fault detectors, our sensors allow the detection and characterization of smaller defects of wires and filaments running at higher speeds and with superior precision.

We take advantage of Swiss tradition in fine mechanics and microtechnology and the use of advanced miniaturized optoelectronics components available from modern optical telecommunications systems.
