High-Level Overview

Coto Technology is a longstanding manufacturer of small signal switching products, including reed relays, reed switches, solid-state relays (CotoMOS®), and TMR-based magnetic sensors.[1][2][3] Headquartered in North Kingstown, Rhode Island, with manufacturing in Mexicali, Mexico, the company serves markets such as Automatic Test Equipment (ATE), Data Acquisition, Instrumentation, Process Control, Telecommunications, Medical, Security, and Battery Management.[1][2][3] It generates approximately $62.2 million in revenue and employs around 419 people, positioning it as a market leader in high-reliability, innovative switching solutions for electronics applications requiring precision and signal integrity.[4]

Coto solves critical challenges in signal switching by delivering products with low thermal EMF, high-frequency performance (>8 GHz), and compact designs like the world's smallest SMD reed relays, enabling reliable operation in demanding environments.[1][2]

Origin Story

Coto Technology traces its roots to 1917 in Providence, Rhode Island, where it began as Coto Coil Incorporated, specializing in coil windings.[1][2][4] In the mid-1960s, it pivoted to reed relays by integrating reed switches into its coils, marking a shift toward switching products.[1][2] Key milestones include the 1970 launch of the first patented low-thermal EMF reed relay, the 1983 introduction of surface-mounted reed relays, the 1994 world's smallest SMD reed relay, and the 2001 patented relay exceeding 8 GHz performance.[1][2]

The company relocated its relay design labs and headquarters to North Kingstown, RI, in 2010 for enhanced efficiency.[1] Further innovations followed with the 2014 CotoMOS® solid-state relay line and the 2016 RedRock™ TMR sensor series.[1][2] This evolution reflects a commitment to magnetics expertise and customer-driven problem-solving, building a reputation over 60+ years through structured teams and quality processes like SPC and FMEA.[2]

Core Differentiators

• Innovation Leadership: Pioneered industry firsts like low-thermal EMF relays, surface-mount designs, and high-frequency (>8 GHz) reed relays, alongside TMR sensors for superior magnetic sensing.[1][2]
• Product Breadth and Customization: Offers reed relays, BGA relays, molded reed switches, solid-state MOSFET relays, and sensors; supports non-standard packages, custom coils, shielding, and multi-pole configs.[1][2][3]
