Reed relays are electronic switches used to isolate two electrical circuits. Since its invention by two scientists in 1933, the reed relay has been widely used in many applications due to its compact size and robust construction. An example is the 9081-05-40 reed relay, which is widely used in telecommunications, medical, industrial and computing applications.

The 9081-05-40 is a latching reed relay, meaning that the switch remains in the same state until instructed to change by an external circuit. This is due to a permanent magnet being used to latch the contact arm together, ensuring that electrical circuits remain isolated. The relay also has a magnetically operated semi-conductor at the base of the switch, which helps control the switching process.

The 9081-05-40 is a single-pole, single throw (SPST) reed relay, which is the simplest type of reed relay. SPST reed relays are most commonly used as low-power isolator switches, such as household appliance circuits or LED indicators. They are generally operated with AC or DC voltage supplies ranging from 2-36 Volts.

In order to operate the 9081-05-40, the control voltage supplies a current to the base of the semi-conductor. This current then causes a magnetic field to be generated, which pushes the permanent magnet off the contact arm. Once the magnet is released, the contact arm is free to move, allowing electrical current to flow between the two connected electrical circuits. This process is also reversible, meaning that the current flowing from the base of the semi-conductor to the magnet will latch the contact arm back together, isolating the two electrical circuits.

The 9081-05-40 is available in a variety of different contact arrangements, including normally open, normally closed, and double throw, depending on the application requirements. It also has two mounting options, a through-hole option for surface-mount applications, and a bulk mount option for more rugged installations.

The 9081-05-40 is widely used in telecommunications, medical, industrial and computing applications due to its robust construction and compact size. It is an ideal choice for any application requiring a reliable, low-power, latching reed relay.
