Murata’s AS-M and AS-V series of anisotropic magneto resistance (AMR) sensors are designed to provide a non-contact magnetic sensor of high sensitivity for use in a relatively low magnetic field.

These devices, the smallest measuring 1.2 x 1.2 x 0.37mm, can detect a magnetic field in either a horizontal or vertical direction.

Compared to traditional magnetic switch components, such as a reed switch or Hall effect IC, AMR sensors are designed to offer high detection sensitivity and a wide detection area.

Within the series, the AS-M15SAH-R and AS-M15KAH-R sensors feature a narrow range of sensitivity, from 0.5 to 1.6mT that suit high accuracy applications.

The AS-M15SA-R and AS-M15KA-R parts have a sensitivity range, from 0.5 to 2.2mT. The AS-V series provides vertical magnetic field detection, and is designed as a more cost effective replacement for Hall IC designs.

Both the AS-M series and AS-V series have the same land compatibility as SOT23 and SON4, and are suitable for reflow soldering.
