Littelfuse LF5346x-08TMR Omnipolar Magnetic Sensors
Littelfuse LF5346x-08TMR Omnipolar Magnetic Sensors are advanced Tunneling Magnetoresistance (TMR) angle sensors designed for high-precision magnetic field detection in demanding applications. These LF5346x-08TMR sensors offer omnipolar operation, meaning they can detect both north and south magnetic poles with equal sensitivity, enhancing design flexibility and simplifying system integration. With ultra-low power consumption and high sensitivity, the LF53464-08TMR and LF53466-08TMR models are ideal for battery-powered and compact devices. These Littelfuse sensors feature a wide operating voltage range and robust performance across temperature extremes, making the devices suitable for use in automotive systems, industrial automation, and consumer electronics. A compact form factor and high reliability also support applications such as rotary encoders, contactless switches, and position sensing in harsh environments.Features
