Part	Spec A	Spec B	Spec C	Spec D	Description

COTO Technology originated in Providence, Rhode Island in 1917 as Coto Coil Incorporated, specializing in coil winding design and manufacturing. Today, the company is a worldwide leader in small signal switching products, serving automatic test equipment, data acquisition, instrumentation, process control, telecommunications, medical, battery management, and security markets.

COTO's product portfolio includes four main product lines:

CotoClassic Reed Relays: Designed for reliably switching low-power signals up to 200W, featuring long life, compact design, and hermetically sealed contacts capable of switching up to 5A current and 7.5kV voltage
CotoClassic Molded Reed Switches: Including the CT04, the smallest molded reed switch sensor available, ideal for security alarms, level sensors, proximity detection, and pulse counters
CotoMOS Solid State Relays: A comprehensive solid state relay line introduced in 2014 for applications requiring high-speed switching
RedRock Magnetic Sensors: Revolutionary TMR-based miniature sensors launched in 2016, offering industry-leading low power consumption for battery-operated proximity sensing and rotation counting

All COTO products undergo 100% testing, backed by the most advanced testing capability of any reed relay manufacturer.
