Reed relays are electromechanical switches that are activated by electromagnetic induction. They are capable of switching both AC and DC circuits, and are commonly used in a wide range of applications. The FRD12049 reed relay is a small-to-medium power device that can handle up to 5A continuous current and up to 10A intermittently. It is a two-winding single-pole double-throw (SPDT) relay, which means it can switch two separate circuits. The FRD12049 is made up of a bifurcated contact and a core with a magnetically sensitive spring. The core and spring are mounted on a highly conductive base plate.

The FRD12049 reed relay is mainly used in communications, consumer electronics, industrial control, military, aerospace and automotive applications. It is ideal for applications where contact reliability and footprint size are important. It is also suitable for low voltage, low current switching, and for making intermittent connections. In addition, it is often used as a signal switch in control circuits, sound alarms, and other similar applications.

The working principle of the reed relay is based on the principle of electromagnetic induction. When a current passes through the copper coil of the relay, an electromagnet is formed. This electromagnet acts upon the magnetically sensitive spring which connects the two reed contacts inside the relay. This connection causes the spring to become magnetized, and it is at this point that the reed contacts are “closed”. When the current is removed from the coil, the electromagnet is no longer active, and the spring becomes demagnetized, which causes the reed contacts to “open”. The FRD12049 reed relay is designed to operate at a maximum current of 5A and nominal switching voltage of 125V.

The FRD12049 reed relay is a great choice for applications that require high contact reliability in a small form factor. It is also a cost-effective choice, as it is much less expensive than other types of relays. It is highly reliable, with an operating life of up to 10 million cycles, and its robust design ensures consistent performance in the toughest of environments.

Overall, the FRD12049 reed switch is a reliable and cost-effective device for switching low voltage/current circuits. It can be used in a wide range of applications, from communications and consumer electronics to military and industrial control. Its robust design ensures that it will provide long-term performance, while its small form factor makes it ideal for applications where size is an important factor. The FRD12049 reed relay is a reliable and cost-effective choice for many applications.
