Coto Technology to showcase its newest TMR magnetic sensor!

Coto Technology, Inc., celebrating 101 years of innovation this year, is a worldwide market leader of advanced switching and magnetic sensing solutions sold into the Automatic Test Equipment, Data Acquisition, Instrumentation, Process Control, Telecommunications, Medical, Consumer & Security Markets. Coto is excited to showcase its newest addition to the RedRock TMR magnetic sensor product line which offers the lowest power consumption, highest sensitivity and smallest size.


  • RedRock™ TMR Magnetic Sensors (RR121 & RR111)
    RedRock™ TMR RR121 Digital Magnetic Sensors & RR111 Analog Magnetic Sensors featuring high sensitivity, ultra-small size and consuming almost zero power, are ideal for applications requiring proximity sensing, rotary sensing, and level detection. ...

  • The RedRock RR121 TMR Magnetic Sensor offers multiple configurations of several parameters to enable applications like proximity sensing, rotary sensing, and level detection. The RR121 features available operate sensitivities from 9 G (0.9 mT) to 100 G (10 mT), and either omnipolar, unipolar, or bipolar magnetic field response. It has the world’s lowest average current drain (190 nA) for an active magnetic sensor, as well as operating frequencies up to 333 kHz and high operating temperature ranges from -40°C up to 125°C.  The RedRock™ RR111 Series is a magnetic sensor with a continuous analog output linearly proportional to an applied magnetic field. Ideal for use in medical, industrial, automotive, and consumer applications, the RR111 enables applications like proximity sensing, and continuous level detection. The RR111 features a low average current drain (1.6 mA) for a continuously active magnetic sensor and temperature range from -40°C up to 85°C.  Both the RR121 and the RR111 are available in an SOT-23-3 package measuring 2.9 x 1.6 x 1.2 mm as well as an LGA-4 package measuring just 1.4 x 1.4 x 0.45 mm.
