Coto Technology RedRock™ 121 RR121-1A53-311 is a digital omnipolar magnetic switch utilizing Tunneling Magnetoresistive (TMR) technology. This surface-mount device, packaged in a SOT-23-3 (TO-236-3, SC-59) configuration, offers detection capabilities for both north and south magnetic poles. It features a supply voltage range of 2.7V to 3.6V and a low supply current of 2.5µA (max). The RR121-1A53-311 exhibits a typical trip magnetic flux density of 0.9mT and a release flux density of 0.5mT, enabling precise switching points. The output is a digital signal, with a maximum output current of 10mA. This component is suitable for applications in consumer electronics, industrial automation, and medical devices where reliable magnetic sensing is required. The device is supplied on tape and reel (TR) for automated assembly and operates within an ambient temperature range of -40°C to 125°C.
