Position Sensors


ams offers a broad range of high-performance position sensors which are suitable for use in industrial, medical, robotics, automotive and consumer applications. Patented technology gives all ams position sensors inherent immunity to external stray magnetic fields, making them highly robust, and lowering system cost because no shielding is needed. ams position sensors are available for use in applications governed by the most stringent safety regulations.


Position Sensors for Automotive


ams enables advanced electrification through a broad portfolio of automotive position sensors.


Our position sensors are truly stray field immune and offer best in class accuracy, reliability and durability even in the harshest automotive environments.


The ams portfolio features:


 AS5715R Inductive Motor Control Position Sensor

 AS5147U High Resolution Rotary Position Sensor

 AS5116 Position Sensor Sin/Cos Output


Position Sensors for Industrial & Consumer


Our position sensors ideally fit into many industrial and consumer devices, due to their:


Best-in-class accuracy

Small form factor (WLCSP)

Programmable low-power modes

Immunity against stray-fields

Attractive pricing


Focus products include AS5600, AS5600L and AS5601 for angle sensing, but also AS5047D for motor control.


AS5047D enables motor drives perform more smoothly and precisely – leading to more efficiency and longer battery life.

State-of-the-art simulation tools (tool link)

Development of measurement set-ups

Supported by our standard end-of-life (EOL) notification policies and follow the supply guarantee period


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!
