Using proven TMR (Tunneling Magnetoresistance) technology, the high-performance RedRock™ RR121 TMR digital logic sensors from Coto Technology offer high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size, all while consuming almost NO POWER! These sensor devices offer multiple configurations of several parameters to enable applications like proximity sensing, rotary sensing, and level detection.
The high-performance RedRock™ series from Coto are TMR magnetic sensors and switches in a standard SOT-23 package. Featuring an incredibly tiny footprint, high sensitivity and low power consumption, this robust product line will fit perfectly into any design where space and power are critical.

The 2362 series reed relay from Coto Technology is the SMD version of the popular 2342 series pico relay. This surface mountable 2 Form C reed relay is designed for high reliability and offers a proven reed design with longer life than competing 2 Form C EMR products.

These reed relays are available with 5V and 12V coil voltages, and are able to switch up to 3W. The
2362 is the ideal solution for automated test, instrumentation and telecommunication applications to increase system reliability and life.

Coto Technology released four new relay families capable of operating in a wide temperature range environments. These relays are intended for automotive, test and/or instrumentation applications that require operating temperature from -40°C to 125°C. The 2270, 2370, 2970 thru-hole and the 9270 (SMD) series have been designed to provide stable contact resistance and relay operation over the full temperature range without de-rating electrical parameters. The relays are available for 5 and 12 volt applications, and feature multi-pole designs with coaxial shield options. All series are RoHS compliant.
