Coto Technology has announced the release of its new RedRock RR111 Series wafer-based TMR (Tunneling Magnetoresistance) analog sensors. Offering extremely strong magnetic sensitivity in an ultra-miniature package size at a highly-competitive price, the RR111 analog sensor is suited for liquid level sensing, precision linear proximity detection, linear positioners and encoders and anti-tampering applications.
Available in both a tiny 1.4 x 1.4 x .45mm LGA-4 device package and an industry standard SOT-23-3 package, the RedRock RR111 fits well into space-constrained applications such as insulin management, ingestibles, and implantable devices that all need to be hermetically sealed. With its high sensitivity, the RR111 operates continuously, changing its output voltage based on the applied magnetic field strength. The highly linear response of the RR111 provides reliable functionality with a wide range of magnets across wide activation distances.
The Coto Technology RedRock RR111-1DC2-331 and RR111-1DC2-332 TMR analog magnetic sensor are immediately available through Coto’s distributors at a single unit price under $1.00 (with high volume application pricing below $0.25).
Coto’s RedRock line of TMR magnetic sensors and switches also includes the RR121 and RR120 Series digital sensors and the RR130 Series digital switch, each catering to the needs of advanced magnetic sensing applications. All offer high sensitivity and ultra-low power consumption in small and ultra-miniature device packaging.
