Littelfuse has announced the release of its highly anticipated 54100 and 54140 miniature Tunnel Magneto-Resistance (TMR) effect sensors. These sensors offer unmatched sensitivity and power efficiency, revolutionizing the magnetic sensing industry.

The key differentiator of the 54100/54140 sensors is their remarkable sensitivity and 100x improvement in power efficiency compared to Hall Effect sensors. These sensors offer activation in the x-y plane instead of the traditional z-axis, providing enhanced functionality. Additionally, they feature a wider operating temperature range of –40°C to +100°C, surpassing other solutions available on the market.

The 54100 and 54140 sensors are well- suited for applications in various markets, including appliances, home and building automation, and industrial sectors.
