AMR sensors allow for horizontal and vertical sensing

Murata has announced the launch of the AS-M and AS-V series of anisotropic magneto resistance (AMR) sensors.

This detection technique is said to provide a non contact magnetic sensor of high sensitivity for use in a relatively low magnetic field. The devices measure 1.2 x 1.2 x 0.37mm and are designed to detect a magnetic field in either a horizontal or vertical direction.

Compared to traditional magnetic switch components such as reed switches and hall effect ICs, Murata claims the AMR sensors have higher detection sensitivity, are more robust and offer a wider detection area.

The sensors are aimed at a range of consumer electronics devices and are suited to open/close detection applications for mobile phones and notebook pcs, as well as industrial and security equipment.

The AS-M series provides horizontal sensing across a wide detection area, allowing for a more flexible approach to sensor and magnet mounting. The AS-M15SAH-R and AS-M15KAH-R sensors feature a range of sensitivity from 0.5 to 1.6mT, while the AS-M15SA-R and AS-M15KA-R parts have a sensitivity range, from 0.5 to 2.2mT and are aimed at lower cost designs.

The AS-V series provides vertical magnetic field detection, and is said to be 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.
