About Coto Technology


The manufacturing plant for Coto Technology’s reed switches and relays is in Mexicali, Mexico. Coto Technology, Inc. was founded in 1917 in Providence, Rhode Island, USA, as Coto Coil Incorporated, a business specializing in the design and production of coil windings. Reed relays, created by incorporating reed switches into coil windings, were added to Coto’s product line in the middle of the 1960s. With the creation of the first Low-Thermal EMF reed relay to be granted a patent in 1970, Coto became a well-known maker of reed relays. Coto later produced the first surface-mounted reed relays in 1983, the most miniature SMD reed relay in history in 1994, and the first reed relay with >8 GHz performance in 2001.


In the areas of Automatic Test Equipment, Data Acquisition, Instrumentation, Process Control, Telecommunications, Medical, and Security, Coto is currently the market leader for small signal-switching products. In addition, manufacturing relay, switch, and sensor products are Coto’s areas of expertise.

FAQ About Coto Technology

Q1: What is a reed switch used for?

A: An electromagnetic switch called a reed switch is used to regulate the flow of electricity in a circuit. They consist of two or more ferrous reeds enclosed in a tiny glass tube-like envelope. The reeds become magnetized and move together or apart when a magnetic field is moved in the same direction as the switch.


Q2: How much power can a reed switch handle?

A: Ratings of up to 15,000 Volts DC are usual on larger evacuated Reed switches. Smaller evacuated reeds can tolerate up to 4000 DC volts. Usually, small pressured reed switches can resist voltages between 250 and 600 VDC.


Q3: How do you protect a reed switch?

A: A series resistor designed to lessen the surge can safeguard the reed switch contact. The filament can also be kept warm using a bias current to avoid the high inrush current.


Q4: Where to order Coto Technology reed switches online?

A: BD Electronics sells Coto Technology reed switches in various configurations. By visiting the BD Electronics website and searching the product category area, you can locate the components you want.
