Coto Technology has announced the release of its new RedRock® RR122-1A22-511 / 512 wafer-based TMR (Tunneling Magnetoresistance) digital omnipolar sensor.

The RR122-1A22 TMR sensor features an operating frequency of 10 Hz, a voltage supply range of +1.7V to +5.5V and an extremely strong magnetic sensitivity (9 G or 0.9 mT) in an ultra-miniature package size at a highly-competitive price.  Boasting ultra low power consumption (75 nA) – the world’s lowest for an active magnetic sensor, the RR122-1A22 Series TMR sensor is ideally suited for performing the “wake up” or “turn on” function for battery operated and power sensitive applications.

Available in either a tiny 1.45 x 1.45 x .45mm LGA-4 device package or an industry standard SOT-23-3 package, the RedRock® RR122-1A22 fits well into space-constrained applications such as insulin management, ingestible, and implantable devices that all need to be hermetically sealed.   The operating temperature ranges from -40°C up to +85°C, although an upgraded version providing high temperatures of up to +125°C is also readily available.
