First Sensor AG

First Sensor AG develops and produces sensor systems and solutions for industrial, medical, and mobility markets worldwide. It offers optical and opto-electronic sensor solutions, including pin photodiodes, quadrant pin photodiodes, avalanche photodiodes (ADP), quadrant ADPs, ADP arrays, position-sensitive diodes, wavelength-sensitive diodes, InGaAs photodiodes, silicon photomultipliers (SiPMs), and phototransistor arrays; optoelectronic modules; and emitters for optical sensors. The company also provides radiation sensors, such as detectors for ionizing radiation and SiPMs; pressure sensor elements and components, pressure sensors and transmitters, and pressure sensors for OEM applications; level sensors comprising hydrostatic liquid level sensors and optical liquid level switches; flow sensors consisting of mass flow sensors for gases and sensors for volumetric flow measurement; inertial sensors; and rugged and compact cameras. In addition, First Sensor AG provides power semiconductors, including power MOSFETs for aerospace applications, as well as radiation-hardened high voltage diodes for space applications; and other products, such as oxygen sensors, miniature solenoid valves, media resistant solenoid valves, electronic pressure controllers, and miniature diaphragm pumps. Further, it sells sensor chips and modules. The company was formerly known as Silicon Sensor International AG and changed its name to First Sensor AG in June 2011. First Sensor AG was founded in 1991 and is headquartered in Berlin, Germany.
