Product Overview
The RedRock RR122-1A52-511 and RR122-1A53-511 are advanced digital magnetic sensors leveraging patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. These sensors are designed for high-performance applications across medical, industrial, automotive, and consumer sectors. They offer a highly sensitive operate point of 9 G with an omnipolar magnetic field response, a wide supply voltage range from 1.7V to 5.5V, and exceptionally low average current drain of 1.0 mA at 250 Hz. With a broad operating temperature range up to 125C, these sensors are ideal for diverse and demanding environments.
