RedRock™ Sensors and Switches

Posted on Thursday, October 6th, 2016

These tiny sensors offer high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size, all while consuming very little power.

The high-performance RedRock™ RR110, RR120, and RR130 meet the strict power constraints of battery-operated portable devices and electronics, suiting the needs of emerging medical device applications including ingestibles and implantables. 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.
