RedRock® RR122-1B12 TMR Digital Magnetic Sensor Released

Coto Technology has announced the release of its new RedRock® RR122-1B12-511 / 512 wafer-based TMR (Tunneling Magnetoresistance) digital omnipolar sensor.

The RR122-1B12 TMR 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 the world’s lowest current drain (50 nA) 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 1.4 x 1.4 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.

 PRICE AND DELIVERY

The Coto Technology RedRock® RR122-1B12-511 / 512 TMR Digital Magnetic Sensor is immediately available through Coto’s distributors at a per unit price of $.60 in volumes of 3000.

Coto Technology Awarded “Best of Show” (Silver) at Sensors Midwest 2017
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.

PRICE AND DELIVERY

The Coto Technology RedRock RR121 TMR magnetic sensor is immediately available through Coto’s distributors at a single unit price of $1.00 (with high volume application pricing well below $0.50).

Re: Notification of Discontinuance of Certain Mercury Relays

In 2007 Coto acquired the assets of SRC Devices.  As part of the acquisition there were over 500 different Mercury parts that were in the portfolio.  Since then we have been utilizing components manufactured by a number of former SRC Vendors, many of which are no longer supporting components, either due to tool wear or a number of other factors.  In addition, there are several parts that have not had any requirements in the ensuing 8 year period.  At this point, Coto does not intend to invest or support selected parts within the following part families, which will be considered obsolete effective immediately. The list of specific parts is too large to include in this notification, so we have provided a link to a PDF file listing all of Coto’s Mercury products – both active and obsolete.   If you would like a sortable, .xls version of this file, you can request one from classic@cotorelay.com.

This action is specific to the listed part numbers designated as “obsolete.” All “active” parts that will continue to be supported are also included in the list to ensure clear direction for parts available for general sale.

As there is a considerable installed base for these discontinued parts we realize that some of you may want to request LTB’s (Last Time Buys).  Please contact your Account Manager for review within the next 30 days.  Please understand that if we are able to support LTB parts then there will be minimum lot sizes and setup costs, assuming components can be made available.
