RedRock® RR142 Multi-Channel Magnetic Sensors Coto Technology RedRock® RR142 Multi-Channel Magnetic Sensors are based on Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. These magnetic sensors offer both digital and analog output options. The digital channels feature an operating sensitivity of 60G (6mT) with an omnipolar magnetic field response and a 12Hz operating frequency. The analog channels offer a -80G to 80G sensitivity range with a sensitivity of 5mV/V/G and enable precise level detection.
