An important tool for determining the strength of a magnetic field is a 3D magnetic position sensor. It can detect linear, angular, rotational, and three-dimensional motions, and it can communicate the data using an output interface.
Using a wide variety of sensing technologies, position sensors can be utilised to monitor either linear or rotating position.
Position sensors are utilised in a wide range of applications; anything that calls for the measurement of movement will employ a particular sort of position sensor.
A 3D position sensor is a specialized device that measures and reports the three-dimensional coordinates of an object or point in space. These sensors are employed in various applications where precise spatial information is crucial. One notable application is in virtual reality (VR) and augmented reality (AR) systems.
In VR gaming, for instance, headsets often incorporate 3D position sensors to track the movement and orientation of the user’s head in real-time. In robotics, 3D position sensors play a fundamental role in enabling robots to perceive and interact with their environment.
Medical applications also benefit from 3D position sensors. Surgical navigation systems use these sensors to track the position of surgical instruments and create 3D maps of the patient’s anatomy in real-time during surgeries.
the new 3DMAG sensors integrate Allegro’s tried-and-tested planar and vertical Hall-effect technologies. This gives them real 3D-sensing capabilities with a broad magnetic dynamic range without saturation.
Due to the sensors’ adaptable 3D Hall front-end and configurable signal processing architecture, they can measure absolute linear position and rotating position up to 360° with high accuracy, which reduces the difficulty of system integration.
The TMAG5170 is the first product in a new series of 3D Hall-effect position sensors that will serve a variety of industrial demands, from general use to ultra-high performance.
A growing number of highly automated systems in smart factories are required to work in a more integrated manufacturing flow while also gathering data to govern processes. Automated equipment needs 3D position-sensing technology to instantly give precise real-time control for better system efficiency and performance while minimizing downtime. This technology has higher precision, speed, and power efficiency.
Vibrations and pollutants from the environment can impair the functioning of shifter systems, passenger restraint systems, and powertrain and chassis applications. When a position sensor is needed in a dirty, high-vibration environment, the assembly of system components can become corrupted by debris and vibration, which can impair the performance of the assembly.
Support components, such as PCBs and capacitors, are typically required for position sensors used in powertrain and chassis applications. In many industrial linear and rotational sensing applications, the same is true. Fitting strong designs within the available unclean, noisy space is a problem for designers.
The Global 3D position sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Melexis’ 3D magnetic position sensors completely transform the market. With the launch of the MLX9042x series, Melexis broadened its selection of 3D magnetic position sensing systems.
These sensors are designed for automotive customers that are on a budget but yet need to correctly and safely monitor absolute position in loud, demanding situations.
The primary target market for the solutions is the automobile industry, specifically customers working on applications like powertrain actuators, transmission sensors, pedal position sensors, and chassis sensors. Improvements made possible by them will also help industrial clients.
The MLX9042x devices all include analogue signal conditioning, data conversion, and signal processing, as well as output stage drivers.
They are based on Triaxis Hall sensor technology, which Melexis invented.The MLX9042x offer comparable performance to the items in the MLX9037x family to assure first-time-right EMC testing.
Because only one test cycle is needed, the design may advance fast and affordably. Reverse polarity is included in the high absolute maximum ratings (AMR), which lowers the frequency of quality events brought on by electrical overstress and enables the fulfilment of varied OEM standards.
These tools enable the design of functionally safe actuators and sensors to guarantee the safe functioning of the vehicle, and they are ASIL B ready (per ISO 26262).
Dual die variants are additionally offered to single die versions for applications demanding a higher level of availability and safety.Support for operational temperatures of 160 °C is another important benefit.
Position sensing applications in hot situations, such as compact engine compartments or when start-stop conditions result in higher heat soaks, are made possible by the high temperature capability.
