About us

First Sensor is one of the world's leading suppliers in the field of sensor systems.

Our company develops and manufactures both standardized and tailor-made sensor solutions for applications in the Industrial, Medical and Mobility growth markets. With over 800 employees, we are represented at six German locations and also have development, production and sales sites in the UK, US, Canada, Singapore, China, the Netherlands, France, Sweden and Denmark along with a worldwide partner network. First Sensor develops and manufactures high-quality, customer-specific sensor solutions for the detection of light, radiation, pressure, flow, level and acceleration. The company produces in-house and along the value-added chain from component to system level.

We guarantee our compliance through regular successful certifications of the sites according to ISO/TS 16949, ISO 14001, EN ISO 13485, EN 9100 and ISO 9001 - matching the respective business field.

Pressure Sensors and Transmitters
A broad selection of piezoresistive pressure sensors and transmitters from 1 mbar up to 1000 bar. Miniature SMT packages for space-saving PCB-mounting or rugged metal housings. For pressure sensing of air and gases or corrosive and aggressive liquids in medical devices, instrumentation and industrial applications.

Liquid Level Sensors and Switches
Contact-free capacitive level sensors for continuous or point level sensing. Hydrostatic liquid level sensors from 0.5 m water column as submersible or externally mounted sensors. Miniature optical liquid level switches.

Flow Sensors
Thermal mass flow sensors for air and gases with fast response times, high sensitivity and bidirectional sensing capability. Small housings with tube fittings or manifold mounting for use in medical devices, instrumentation and HVAC applications. Differential pressure sensors for volumetric flow measurement of liquids and gases.

Oxygen Sensors
Non-consumptive zirconium dioxide technology for virtually unlimited lifetime. Highly stable and accurate oxygen concentration measurement from 0...100 %Vol. Easy calibration without the need of a reference gas. Custom specific modifications or designs to fit special requirements.

Air Bubble Sensors
Non-invasive sensors for air and gas bubble detection in liquids. Complete media compatibility and sterility for many critical medical, analytical and industrial applications.

Valves and Pressure Controllers
Miniature switching and proportional solenoid valves as well as highly media resistant valves for aggressive liquids and gases. Electronic pressure controllers for closed-loop proportional pressure or vacuum control. High performance solutions integral to many medical and analytical devices.

Miniature Pumps
Miniature liquid and pneumatic diaphragm pumps. Low power consumption and optimised flow paths. Ideal for OEM device manufacturers in the medical, analytical, laboratory and instrumentation market.

First Sensor offers a wide range of photodiodes with high sensitivity, high speed and low dark currents. Our detectors are optimized for ultraviolet, visible and ionizing radiation and can be combined with SMD (surface mount device), THD (through hole device) and TO (metal cans) housing technologies. Our portfolio includes Avalanche photodiodes (APD), PIN photodiodes, position sensitive photodiodes (PSD), and Quadrant photodiodes (QP).

First Sensor provides the ideal emitter for detector solutions. For the wavelength range between 635 nm and 905 nm we carry a wide range of laser diodes (LD). The high-quality lasers are available as single mode or as multimode lasers. For industrial applications, First Sensor offers optimized light-emitting diodes (LEDs) with center wavelengths between 365 nm and 950 nm. The range includes point light sources and surface emitters. We are also happy to adapt the emitter to suit your individual application. Ask us for a customized First Sensor solution.

Radiation Sensors
Atomic particles with sufficient kinetic energy and X-rays can be detected directly via their absorption on the crystal lattice or indirectly via scintillators with silicon radiation detectors. This can require very high absorption volumes and extremely low dark currents, in some cases with fully depleted wafers. First Sensor offers solutions for energy-dispersive spectroscopy. Special features are wafer thickness up to 700 µm, very low dark current signals, very low capacitance level, minimal series resistance at full depletion.
