Position Sensor ICs

ams’ contactless position sensors deliver best-in-class strayfield immunity, superior durability and adherence to the most stringent safety requirements.

New Product: AS5172

High-Resolution On-Axis Magnetic Angular Position Sensor with PSI5 Output

ams’ new AS5172 complements the ams 70-series of high-resolution angular position sensors. The AS5172 has a highly reliable and fast PSI5-bus interface, which can transmit a 12-bit angle information over high secure data bus according to newest PSI5 standards (PSI5 specification Version 1.3 and 2.1).

System in Package (SiP)

Watch this video explaining ams' system in package design, which does not require circuit boards. With a system in package product design the unit sensor and the associated external components are integrated into one small housing.

Everything is theoretically impossible, until it is done.



Position sensing is key for robots to control position, orientation or motion of the robotic joints.
ams magnetic position sensors bring to the market, high accuracy, very low power consumption, and ultra-small packaging solutions that are critical in robot motor joint control. ams magnetic position sensors are unique to the market as they are immune to magnetic stray fields, and provide very low propagation delay and ultra-fast output refresh rates.

Industrial / Consumer

ams’ magnetic position sensors are suitable for many application because of an easy and flexible sensor configuration and the reliability in the harshest environments.

Automotive - Car


ams’ magnetic position sensors meet the stringent requirements for the most challenging safety critical applications and are available with automotive qualification using ISO 26262 safety standard.


Stray Field Immunity

Stray Field Immunity is a unique patented technology by ams, protecting sensors from interfering magnetic fields. Additional external shielding variants are not necessary because the SFI-technology is integrated into the IC, which decrease costs at the final application level.

System in Package

With SiP technology the unit sensor and associated external passive components are integrated into one small housing. This reduces the footprint, lowers system costs, and frees the manufacturer of the need and cost to develop and assemble a PCB. A SiP is far less sensitive to incorrect placement. Therefore, it provides more accurate and reliable sensor measurements. SiP is flexible in its installation and orientation.
