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.

Coto Technology has announced the release of its new RedRock® RR122-1A22-511 / 512 wafer-based TMR (Tunneling Magnetoresistance) digital omnipolar sensor.

The RR122-1A22 TMR sensor features an operating frequency of 10 Hz, a voltage supply range of +1.7V to +5.5V and an extremely strong magnetic sensitivity (9 G or 0.9 mT) in an ultra-miniature package size at a highly-competitive price.  Boasting ultra low power consumption (75 nA) – the world’s lowest for an active magnetic sensor, the RR122-1A22 Series TMR sensor is ideally suited for performing the “wake up” or “turn on” function for battery operated and power sensitive applications.

Coto has collaborated with MikroE in their new TMR mix-sens Click Board to target product development engineers who currently use or might use the MikroE ecosystem to speed prototype and development of products using Coto RedRock® TMR magnetic sensors.

May 11, 2020 — In collaboration with Coto Technology,  MikroE, an industry leader in embedded computing development platforms, has incorporated RedRock® TMR magnetic sensing capabilities onto a MikroE Click board form factor.  The TMR mix-sens Click Board is supported by a mikroSDK compliant library, which includes functions that simplify software development.  This Click board™ comes as a fully tested product, ready to be used on a wide variety of system development platforms equipped with the mikroBUS™ socket.    TMR mix-sens Click is targeted towards development engineers who currently use or might use the MikroE ecosystem to speed prototype and development of products using Coto RedRock® TMR magnetic sensors.

Coto Technology’s RedRock™ RR111 Series TMR Analog Magnetic Sensors offer high sensitivity and an even smaller package size than previous TMR analog technologies.

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 ideally 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.

New RedRock TMR Magnetic Sensors capture attention of Electronic Engineers/Designers

Rosemont, IL – Coto Technology has been awarded Sensors Midwest’s Best of Show “Silver” award for its newly-released RedRock TMR RR121 Magnetic Sensor.  Seeking to replace aging magnetic sensor technology, the RR121 represents a huge breakthrough for design engineers seeking the lowest possible power consumption and highest sensitivity in an ultra-miniature package.  Released on October 3, the RR121 magnetic sensor series will address new generation requirements in multiple markets including medical, industrial, security, white goods and automotive.  Design engineers using older technology switches and sensors will no longer have to suffer the detractions in power, size, sensitivity and cost – and will now have greater flexibility and reliability as well as cost efficiency.  The RR121 offers the lowest power, highest sensitivity in the smallest package available in the world!

The RR121 is ideal for applications including medical, industrial, consumer, automotive, security, and energy industries where very low average current consumption, high sensitivity, and a small package size are required.  Specific medical applications include portable and battery-powered medical devices like ingestibles and implantables that are hermetically sealed and need a way to be triggered without compromising their protective encasement.  Many of these devices, such as capsule endoscopes, remain in “standby mode” on a doctor’s shelf for up to 18 months – so battery power conservation is critical.  The small size of these types of medical devices and the need for hermetic seals to survive the gastrointestinal tract necessitates a tiny, contactless means for “waking up” the microprocessor from outside of the body. Magnetic sensors are also used in some hearing aids to provide a means of mode

switching, whether it be for turning the device on or off, performing diagnostic checks, or tuning the hearing aid’s response when a telephone speaker is brought near the ear.  The RR121 is ideal for consumer appliances requiring accurate liquid level measurement, such as dishwashers, washing machines, coffeemakers, and refrigerators. The RR121 can replace historically-used large reed switches to provide a more accurate measure of the liquid level, saving energy, water usage, and costs for consumers while improving sustainability for the environment. It can also be used to measure flow of both liquids and gases in these same applications to ensure that the devices are operating accurately. That flow measurement can also be utilized in residential and commercial water meters to provide accurate reporting of usage while the unipolar response can act as an additional inherent resistance to tampering.  With regard to utility meters, the RR121 can replace reed switches used in the rotational counting common to gas and electric meters as well as provide a fail-safe activation method for the wireless circuit that facilitates remote measurement as advanced metering systems replace aging infrastructure in the US and overseas.  The RR121 also provides a smaller, more robust solution for residential and commercial security systems. Its small size and high sensitivity allow it to be embedded into doors jams and window sills to monitor their opening and closing and prevent unauthorized entry. They can even be integrated with ambient light sensors as part of automated window blinds that adjust to reduce solar heating, saving homes and businesses on HVAC energy costs.
