Product Overview
The RedRock RR122-1B52-511 and RR122-1B53-511 are digital magnetic sensors leveraging patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. Designed for medical, industrial, automotive, and consumer applications, these sensors offer an omnipolar response with an operate sensitivity of 30 G. They feature a wide supply voltage range from 1.7V to 5.5V, low average current drain of 1.0 mA, and operate at 250 Hz. With a high operating temperature range up to +125C, they are suitable for demanding environments. Applications include proximity detection, rotary sensing, fluid level detection, and motor control.
