Reed relays are electrical switches made from an energized coil wrapped around a pair of tiny contacts or reed blades. 7302-24-1000 are high-performance, low-level reed relays designed for a wide range of applications. They offer excellent isolation, long life and high-speed switching.

Application Field

7302-24-1000 reed relays are particularly suited for applications that require the transfer and transmission of low-level signals, especially those with frequency ranges between 1–10 kHz. 7302-24-1000 are much more reliable than electromechanical relays when it comes to low-level signals because they can handle signals as low as 0.5 mA without compromising performance. 7302-24-1000 can be used in various applications such as test and measurement, industrial automation, medical equipment, access control systems, and security systems.

Working Principle

The 7302-24-1000 reed relay is energized when a low voltage is applied to its coil, usually between 1.5-12V DC. This energization causes a magnetic field which attracts the reed contacts and closes the circuit. When the magnetic field is removed, the reed contacts open and the circuit is switched off. The reed contacts are made of special alloy material which ensures a reliable and steady performance for thousands of switching cycles.

7302-24-1000 is also equipped with a built-in diode which provides protection from excessive current and voltage surges. The diode enables the relay to handle higher voltage and current, as well as providing protection against surge damage. The diode is also an important factor in maintaining the performance of the relay over time as it minimizes contact corrosion.

7302-24-1000 reed relay also offers excellent isolation. This means that the relay is completely isolated from the external environment, allowing it to switch high voltage and current without heat or arcing. This makes it ideal for applications that require high accuracy, sensitive switches and reliable performance in even the most demanding applications.

Conclusion

7302-24-1000 reed relays are designed to handle a wide range of low-level signals and offer excellent isolation, long life and high-speed switching at a very attractive price. The built-in diode provides additional protection against excessive current and voltage surges, which improves reliability and maintains performance over time. 7302-24-1000 is ideal for applications that require reliable performance and high accuracy.
