RedRock™ RR1xx Sensors and Switch

Coto Technology's RedRock™ RR110, RR120, and RR130 offer high magnetic sensitivity while consuming very little power

Image of Coto Technology's RedRock™ RR1xx Sensors and SwitchCoto Technology's high-performance RedRock RR1xx sensors and switch meet the strict power constraints of battery-operated portable devices and electronics, while suiting the needs of emerging medical device applications including ingestible and implantable types. Using proven TMR (tunneling magnetoresistance) technology, the small package size addresses the needs of current medical applications (such as portable insulin pumps, capsule endoscopes, medical wearables, etc.) as well as consumer smart wearables, high-precision fluid level sensing, security and anti-tampering, "wake up" mode switching on a microprocessor, and more.
