Coto Technology has announced the release of its new?

RedRock? RR122-1B12-511 / 512 wafer-based TMR (Tunneling Magnetoresistance) digital omnipolar sensor.

The ultra low power RR122-1B12 TMR magnetic sensor features an operating frequency of 2 Hz, a voltage supply range of +1.7V to +5.5V and an extremely strong magnetic sensitivity (30 G or 3 mT) in an ultra-miniature package size at a highly-competitive price. ?Boasting ultra low power consumption (50 nA) – the world’s lowest for an active magnetic sensor, the RR122-1B12 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? RR122-1B12 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 allowing high temperature operation of up to +125°C is also readily available.
