MagnetIQ designs and manufactures magnetic sensor assemblies for high-precision position, speed, and angular sensing. We combine permanent magnets with integrated mechanics, housings, and alignment features — delivering reliable and ready-to-integrate modules. Our magnetic sensing solutions are used in industries where accuracy, repeatability, and environmental resilience are critical, such as automotive, industrial automation, robotics, and medical devices.
Sensor Assembly
What is a Sensor Assembly?
A magnetic sensor assembly is a complete module that combines a calibrated magnet and a sensor interface in a mechanically defined position. These assemblies are pre-engineered to deliver accurate magnetic fields to sensor chips, ensuring consistent and repeatable performance across applications like speed sensing, position detection, and angular feedback.
Sensor assemblies may also incorporate shielding to minimize interference, mechanical indexing to ensure correct installation, encapsulation for environmental sealing, and centering mechanisms for precise alignment. By consolidating these features into a single unit, we make the integration of magnetic sensors into complex systems much simpler, safer, and more predictable.
Assemblies are tailored for radial, axial, and linear geometries and are optimized based on factors like air gap, magnetic flux strength, and temperature stability.
How do magnetic sensor assemblies improve accuracy?
Magnetic sensor assemblies improve accuracy by controlling critical tolerances between the magnet and sensor, eliminating field variation due to misalignment or shifting. Integrated designs also reduce external magnetic interference and mechanical play, helping the system maintain precision even under vibration, temperature fluctuation, or long-term use.
What types of magnetic sensors require aligned assemblies?
Hall-effect sensors, AMR (anisotropic magnetoresistance), GMR (giant magnetoresistance), and TMR (tunneling magnetoresistance) sensors all benefit from aligned magnet assemblies. These sensors depend on precise magnetic field orientation and strength, which can only be guaranteed through tightly controlled, pre-assembled modules.
