The RedRock RR110 wafer-based tunneling magnetoresistive (TMR) analog sensor offers strong magnetic sensitivity, high directionality, and a small package size. The component suits continuous fluid measurement applications including countertop appliances, white goods, utility meters, medical devices, security and anti-tampering applications, industrial positioning, and other proximity sensing applications. With minimal design effort, the RR110 can easily replace a complicated, costly, and vulnerable bare glass reed switch ladder like those often seen in fluid level sensing applications with a single sensing element. The highly linear response of the RR110 provides reliable functionality with a wide range of magnets across wide activation distances. The sensor features high resistance to shock and vibration while the industry standard SOT-23 package provides a ruggedized package that can handle tough environments. Likewise, it ensures maximum manufacturability for automated pick and place operations. Single unit price of $2.95 each with high volume application pricing below $0.50 each. Find a datasheet at
