Littelfuse has announced the launch of two new TMR-based magnetic angle sensors – the LF53466 and LF53464 – designed to deliver high-precision 0–360° angular measurement in harsh environments with minimal thermal drift. Both sensors utilize Tunneling Magnetoresistance (TMR) technology in a dual push-pull Wheatstone bridge configuration, each featuring four high-sensitivity sensing elements, which enable accurate angle detection along the X and Y axes. These sensors offer a compelling alternative to Hall-effect devices by providing exceptional thermal stability, wide supply voltage compatibility, and enhanced measurement precision. The LF53466, housed in a standard TSSOP8 package, offers precision angle sensing with an error of less than 0.8° in the 200–800 Gs magnetic field range. It is ideal for industrial and automotive applications that benefit from stronger mechanical solder joints and ease of inspection—such as steering wheel angle sensors, pedal position sensors, and contactless potentiometers. The LF53464, available in a compact LGA8L package, achieves even greater accuracy—angle error below 0.6°—while enabling wider airgap capability and compatibility with smaller, lower-cost magnets. It is well-suited for space-constrained applications such as rotary encoders, knob and valve position sensing, and consumer devices including power tools and appliances.
