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 […]
How can you use a three-axis position sensor?
At Sensor Expo 2017, Nick Czarnecki, regional marketing manager from Melexis, demonstrates concepts for position sensing using the company’s MLX90393 Triaxis position sensor in human machine interface (HMI) applications that include rotation, push detection and controlling 3D motion with a joystick. The demo shows how a non-contacting rotating knob can set the absolute axis position […]
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 […]
Magnetic Field and Time-of-Flight Sensing
At Sensors Expo 2016, Liesbet Stalmans and Joe Rotole from Melexis demonstrate the company’s MLX30393 Triaxis Micropower Magnetometer (Magnetic Field Sensor)and the MLX75023 QVGA Time-of-Flight (ToF) Sensor for Automotive and Industrial Applications. For more information about the MLX30393 or MLX75023, click the part number.
Hall Effect Switch Uses Only Two Wires
With its MLX92242, Melexis Technologies NV Hall effect switch/latch IC can be programmed at the end of a production line to meet the mechanical tolerance requirements of the application. Set via the sensor’s VDD pin, EEPROM programmable memory is used to adjust the various tolerances. Instead of 3-wires, the 2-wire units only use the VDD […]
Improved Linear Hall Effect Sensor Delivers 3µs Response Time
Control in applications such as electric and hybrid vehicles, solar power and other high power electronic systems relies on current sensing and Hall effect devices are a popular technology for this purpose. With these kind of applications in mind, Melexis engineers designed an improved MLX91209CA high-speed linear Hall IC that achieves a response time of […]
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 […]
