Melexis has introduced the MLX92442 Induxis switch, which offers a contactless and magnet-free monolithic design to directly detect conductive targets, facilitating small module designs with reduced component count for various applications such as high voltage interlocks, charging flaps, seatbelts, hood/trunk, gear tooth sensing, or brake-by-wire systems. Traditional safety automotive latches and switches typically rely on […]
Teardown: Inside an industrial absolute encoder
If you go to the Wikipedia page on absolute encoders, you’ll find descriptions of these devices mentioning multiple code rings, glass or plastic discs, and configurations of sliding contacts arranged so each contact wipes against a metal disc at a different distance from a turning shaft. Actually, you’d be hard pressed to find any of […]
Tactile sensor targets robotic hand applications
Melexis has made a major innovation to improve robots’ ability to interact with fragile or diverse objects. The company has unveiled Tactaxis, a fully integrated tactile sensor that is compact, soft, and provides the 3D force vector acting on its surface. This improves robots’ hands and grippers, making delicate operations such as fruit picking possible. […]
What is the difference between a thermal IR sensor and a quantum IR sensor?
Infrared radiation (IR) can be detected by thermal IR and quantum IR sensors. A thermal IR sensor uses infrared energy as heat for detection and its sensitivity is independent of wavelengths. Therefore, it can detect objects in the near IR, mid IR, and far IR bands. The non-contact detectors do not require cooling after exposure […]
What’s new in magnetic position sensors?
At Sensors Expo 2018, Vinicius (Vinnie) Cardoso, a field application engineer at Melexis, demonstrates the capabilities of the company’s magnetic position sensors. Using an extremely eye catching 3-D LED structure, he shows how the MLX90333 Triaxis® position sensor indicates the position of a magnet. With red and blue LEDs indicating the north-south poles of a […]
Where can time of flight sensing be used?
At Sensor Expo 2017, Doug Gates, a technical sales manager from Melexis explains the applications for his company’s two-chip semiconductor solution for time of flight (TOF) sensing. Time of flight sensing uses optical, acoustic, electromagnetic or other wave techniques to measure the time that it takes for the source to travel a distance through a […]

AEC Q100 Qualified Automotive Pressure Sensor
Designed for 1 Bar (14.7 psi) automotive applications, Melexis MLX90809 pressure sensor meets Automotive Electronics Council (AEC) Q100 requirements. The piezoresistive microelectromechanical system (MEMS) technology sensor and its signal conditioning circuitry are fabricated in a standard CMOS process producing a completely monolithic sensor on the same wafer. Signal conditioning includes a low-noise analog front end […]
Use 12-bit Resolution Sensor in Either Linear or Rotary Position Sensing Systems
Melexis uses its proprietary Triaxis technology in the MLX90365 position sensor to measure the properties of a magnetic field in all three dimensions. The sensors are offered in SOIC and TSSOP surface mount packages and use passive protection components mounted on the PCB. Consequently, 12-bit resolution devices can be used in either linear or rotary […]
