The AMR132x series includes AMR1320 and AMR1321 omnipolar omnidirection magnetic switches. Unlike most magnetic switch sensors that respond to magnetic fields along a single direction, these sensors detect magnetic fields from any direction within 360°. This unique capability provides a cost-effective alternative to Reed switches for magnetic tamper detection in utility meters including water, gas and electricity meters, and many magnetic-activated proximity switches. AMR1320 and AMR1321 feature ultra-low power consumption at 1~3 microAmpere, enabling extended lifetime for battery-operated sensor applications.

Designed for pneumatic cylinder position sensing, the AMR1341 and AMR1342 omnipolar magnetic switches feature accurate switching points with low hysteresis, two sensitivity settings for different magnet types and stroke lengths, and effective double-switching suppression. The 1kHz high-speed operation, low-power consumption of 40 microAmpere, ultra-compact packages, and a wide range of supply voltage from 1.6~5.0V make them adaptable to a variety of applications.

Key features of AMR132x and AMR134x series include:

Part Number	Sensitive Direction	Supply Voltage (V)	Average Current (µA)	Switching Frequency (Hz)	BOP (Gauss)	BRP (Gauss)	Output signal	Packaging type
AMR1320	360°	1.8~5.5	1	30	±17	±12	CMOS active- low	SOT23-3
AMR1321			3	100	±25	±20
AMR1341	X-axis	1.6~5.0	40	1000	±15	±10	CMOS active- high	DFN3L 2*2*0.55mm LGA3L 2*1.5*0.63mm
AMR1342					±35	±27

MDT's AMR sensor portfolio includes AMR switch sensors, AMR angle sensors, AMR linear sensors and AMR magnetic scale sensors. MDT's AMR sensors complement its TMR sensor product series, providing customers with an extensive selection of magnetic sensing solutions for new product development or replacing legacy products. By leveraging MDT's cutting-edge magnetic sensing technologies, customers can expedite their time-to-market and achieve an enhanced return on investment. All of MDT's AMR and TMR sensors are available to order from Digi-key.
