Coto Technology RedRock® RR122 TMR Digital Magnetic Sensors
Coto Technology RedRock® RR122 TMR Magnetic Sensors are digital magnetic sensors ideal for medical, industrial, automotive, and consumer applications. RR122-1B12-51x Sensors offer the industry's lowest average current drain (50nA) for an active magnetic sensor. Coto Technology RedRock RR122 TMR Magnetic Sensors provide an omnipolar push-pull response and a wide supply voltage range from 1.7V up to 5.5V.Due to ultra-low power, high sensitivity, miniature size, and robustness, these TMR sensors are a popular alternative to Hall Effect and Reed Switches. The RedRock® RR122 series incorporates digital magnetic sensors ideal for use in medical, automotive, and consumer applications. It is based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. These tiny sensors from Coto Technology offer high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size while consuming extremely low power.
