About Coto Technology

Coto Technology makes small-signal switching and magnetic sensing products. Its main lines are CotoClassic reed relays and molded reed switches, CotoMOS MOSFET solid state relays (including high-voltage and high-current versions), and RedRock TMR magnetic sensors and switches. Custom package sizes, pinouts, coil and shielding designs, and multi-pole configurations are available.

Coto's products go into automatic test equipment, data acquisition, instrumentation, process control, telecommunications, medical, battery management, solar and security markets. Recent work focuses on high-voltage reed relays for green energy, EV and high-end medical equipment. RedRock sensors are aimed at low-power battery-operated devices for proximity sensing, rotation counting and linear sensing.

The company started in Providence, Rhode Island, in 1917 as Coto Coil Incorporated, a maker of coil windings, and has made reed relays for more than 60 years. Reed relays and reed switches are manufactured at Coto's facility in Mexicali, Mexico, which also offers contract manufacturing. Coto is certified to ISO 9001:2015, its standard products are RoHS compliant, and it says every product is 100% tested.
