Power relays are vital components of electronic circuits, offering protection of circuits from overload and overcurrent conditions as well as switching of the circuits. Under the power relays, over 2 Amps, 18782N200 is a popular choice. This paper will introduce the application field and working principle of 18782N200 and discuss its feature.

The Application Field of 18782N200 Power Relays

The 18782N200 belongs to the power relay family. Its maximum switching current can reach 2 amps and it is a compact design with a width of just 1.6 inches. Due to its small size, it is widely used in the electronic industry. It can be applied in domestic appliances, medical instrument, automatic control system, etc. Due to its robust construction, it can be used in both indoor and outdoor applications, and provide stable performance in extreme environments.

Working Principle of 18782N200 Power Relays

The 18782N200 electromagnetic power relays consist of several basic subsystems: the electromagnet, the armature, the contacts and the mechanical springs. When current passes through the electromagnetic coils, they generate a magnetic field that can attract the armature and engage the contacts. The contacts can be located at different points in the magnetic field, and thus close or open the circuit. The armature and the metallic springs ensure the relays return to its original state when current stops flowing. The 18782N200 also has a built-in diode, which protects the relay from sudden voltage drops.

Features of 18782N200 Power Relays

The 18782N200 has a few unique features that make it ideal for applications requiring high switching currents up to 2 amps. Firstly, the 18782N200 is designed with an internal damping mechanism that absorbs noise and vibration when switching. Secondly, its signal-to-noise ratio is high, resulting in high-precision switch control. Thirdly, the 18782N200 is rated for an operating temperature range from -40 degrees Celsius to +85 degrees Celsius, making it suitable for use in extreme environments. Finally, the 18782N200 is UL and CSA approved, giving it accepted safety and performance standards.

Conclusion

The 18782N200 power relays are a reliable, versatile and powerful partner for any electronic device that requires high-current switching. With its small size and robust construction, it’s suitable for both indoor and outdoor applications. It is UL and CSA approved and delivers reliable performance in extreme environments. Additionally, features such as its internal damping mechanism, high signal-to-noise ratio and wide operating temperature range make it an excellent choice for most high-current switching applications.
