描述
Littelfuse LF5346x-08TMR Omnipolar magnetic sensor
Littelfuse LF5346x-08TMR omnipolar magnetic sensors are advanced tunnel magnetoresistive (TMR) angle sensors designed for high-precision magnetic field detection in harsh applications. These LF5346x-08TMR sensors are omnipolar, meaning they can detect both north and south magnetic poles with equal sensitivity, increasing design flexibility and simplifying system integration. The LF53464-08TMR and LF53466-08TMR models feature ultra-low power consumption and high sensitivity, making them ideal for battery-powered and compact devices. With a wide operating voltage range and robust performance under extreme temperature conditions, these Littelfuse sensors are suitable for automotive systems, industrial automation, and consumer electronics. The compact form factor and high reliability also support applications such as rotary encoders, contactless switches, and position sensing in harsh environments.characteristic
