Reed relays are relay switches that operate on the basis of the contact of magnetic material inside a vacuum or inert gas sealed tube. They use an electromagnet to open and close the contacts of a hermetically sealed reed switch. This type of relay offers greater reliability and low power requirements. The SBR424SD is a special type of reed relay suitable for applications in the automotive, industrial, telecoms and military markets. This article will look at the application field and working principle of the SBR424SD reed relay.

The SBR424SD is a reed relay designed to switch DC and AC power on and off. It is a miniature, solder type relay that is hermetically sealed and has a maximum switching capacity of 28 Vdc/50 Vac and a maximum carry current of 500 mA. The relay has an open air gap of 1.4mm and a contact resistance of 200 milliohms (mΩ). The contacts on the relay are designed for a reliable, low contact resistance and high switching capacity of up to two million cycles.

The SBR424SD is suitable for applications in both industrial and telecoms markets. It is designed for use in telecom central offices, telephone exchanges, and optical equipment. In the industrial sector, the relay is suitable for applications such as automobiles, process control, motor controls, and instrumentation systems. The SBR424SD also has other applications in the military, medical, and industrial control markets.

The working principle of the SBR424SD reed relay is based on a principle known as a “magnetically actuated switch”. Inside the hermetically sealed reed switch, two polar magnets are used to move a contact element connected to a current carrying element. When the current is applied, the opposing polarity of the two magnets will cause them to attract each other, which in turn will cause the contact element to move as well. When this happens, an electrical connection is made and the circuit is then “closed”. To open the circuit, the current is reversed and the magnets move away from each other, thus breaking the electrical connection.

The SBR424SD reed relay is a reliable and versatile solution for switching, as it can switch up to two million cycles. It is a low power consumable device that is well suited for applications in the industrial and telecom markets. The reed relay is cost-effective, making it an attractive choice for companies looking for a reliable and cost-effective solution.

The SBR424SD reed relay is a reliable and cost-effective solution for the switching requirements of both industrial and telecom applications. The operation of the relay is based on a magnetically actuated switch, allowing the user to switch AC and DC current with low power consumption. The reed relay is also designed to last for up to two million cycles, making it an ideal solution for companies looking for a reliable and cost-effective solution for their switching applications.
