Ultraminiature TMR-Based RedRock Switches / Sensors Products Debut at Electronica Germany, 2016

Exhibiting in Hall B1, Booth #525 at Electronica Germany, Coto Technology Inc. will be showcasing its newly-released RedRock™ RR110 analog sensor, RR120 digital sensor, and RR130 digital switch.  With a standard SOT-23 package, these devices are half of the size of Coto’s CT05 molded reed switch. The high-performance RedRock RR110, RR120, and RR130 have numerous technologically-advanced applications in multiple markets.   Offering both high sensitivity and small package size, the devices are ideally suited to the demands of next generation medical, automotive, instrumentation, and industrial applications. The tiny sensors offers high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size, all while consuming very little power.

The 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. The small package size addresses the needs of current medical applications including portable insulin pumps, capsule endoscopes, next generation hearing aids, insulin pens, medical wearables, and other small, battery-powered medical electronic devices. Other applications include consumer smart wearables, high precision fluid level sensing, security and anti-tampering, “wake up” mode switching on a microprocessor, and more.


The Coto Technology RedRock RR110, RR120, and RR130 TMR magnetic sensors and switches are immediately available through Coto’s distributors at a single unit price of $2.95 (with high volume application pricing under $0.99). An evaluation kit (RR110-EK) is also available through Coto’s distributors. The kit contains a motherboard, both an RR110 and RR130 mounted at opposite ends, a magnet, and other accessories along with documentation.


For more information on RedRock™ sensors and switches as well as other Coto Technology products, please visit or email directly.

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

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.


New CotoMOS® 140 Series MOSFET Relay Handles 1500V

Coto Technology has released the new CotoMOS® 140 Series solid state relay for high-voltage switching applications. The CotoMOS® 140 series has a load voltage of 1500V and a Load Current of 45mA Max. AC/DC, configurable to 70mA in DC Mode.
