Angle Position On-Axis

The magnetic rotary position sensor product family detects the absolute angular orientation of an on-axis two-pole magnet rotating over the center of the IC. The absolute angular position can be provided in various formats, including PWM, ABI and UVW, or directly read through the host interface. According to the application’s requirements, resolutions from 8-bit up to 14-bit are available. This technology can be employed in high-accuracy angle position detection, high-speed rotation systems and brushless DC motor control. Any rotary magnetic position sensor can replace either absolute or incremental optical sensors, other magnetic and inductive technologies, potentiometers or magnetic switches.

Linear Position

The linear magnetic position sensor product family measures the linear movement of a multi-pole magnetic strip. Circular multi-pole magnetic rings can also be used in rotary incremental rotation off-axis applications. This high precision product family allows the user to detect linear movement with a resolution as fine as 0.5μm. All products are aimed at applications which require extreme precision, accuracy, dynamic range and ultra-low power consumption.

Inductive Motor Control

The inductive motor control position sensor family detects the electrical position within one pole-pair of a rotating shaft and can be used for the motor commutation of a brush-less DC (BLDC) motor. Based on the inductive sensor technology, this family measures the coupling between an excitation coil (TX) and two receiver coils (RX) via a rotating target. The coils are executed as printed circuit coils and the rotating target is a simple punched metal part. With the correct layout of the coils and the target, both synchronized to the number of pole-pair count of the motor, the IC output is proportional to the electrical angular position within one pole-pair segment with increased resolution and high performance of only 0.3° electrical INL!
