The classic sensor for detecting metal objects: maintenance-free measuring principle, high frequencies and very small dimensions.
Tried and tested technology combined with our know-how and innovations solve even the most critical object detection problems.
The smallest and lightest on the market, with robust housings and sonic cone profiles for almost all applications.
Detection with high sensitivity for water-based media and bulk goods even through container walls.
Precision mechanical switches
Accurate down to the micrometer. Still to this day, we provide the most accurate and compact mechanical limit switches in the world.
These long-running sensors perform up to 20,000 measurements per second, use contactless measuring methods and are maintenance and wear-free.

Areas of application
First Sensor develops and manufactures high-precision optical and opto-electronic sensor solutions from a single source and provides long term supply continuity. Available as component, module or system solution First Sensor products are an integrated part of our customers application.
Alpha, beta, gamma, and X-ray radiation can be detected with silicon PIN photodiodes either directly via the absorption in the crystal lattice or indirectly via the measurement of the luminescence radiation of a scintillation crystal. The Series X from First Sensor features optimized silicon PIN photodiodes, which form wide, fully depleted space-charge regions even at low reverse voltages in order to guarantee the maximum absorption of radiation. For high-energy radiation we offer detectors with a CsI:TI scintillation crystal.
First Sensor features a highly innovative technology platform for manufacturing high-precision inertial sensors for geoengineering, condition monitoring or navigation applications. The MEMS sensors allow for flexible customization to fit your individual application requirements.
