These tiny TMR Magnetic sensors offer high magnetic sensitivity, EMF resistance, and a small package size, all while consuming almost NO POWER.

The RedRock™ RR121 Series TMR Digital Magnetic Sensor is a digital logic sensor ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RR121 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.  Download the RR121 Digital TMR Magnetic Sensor Datasheet Here.

The high-performance RedRock™ RR110, RR120, and RR130 TMR magnetic sensors 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.   Download the complete catalog containing datasheets for all three RedRock Sensors along with sensor & switch packaging, pad layout, reflow profile, glossary, and sensitivity maps.

cotoClassic

Coto Classic Molded switches are the single-pole, single throw (SPST) type, having normally open ruthenium contacts. The sensor is a double-ended type and may be actuated with an electromagnet, a permanent magnet or a combination of both. The CT05 (5mm / 5W) is designed for SMD mounting and is available in Gull Wing or J-Lead configurations. The CT10 (10mm / 10W) is designed for SMD mounting and is available in Gull Wing, J-Lead, and axial configurations.    Note: The new CT10-G2 is 260°C process temperature hardy!
